PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2025; 340:126347. [PMID: 40347775 DOI: 10.1016/j.saa.2025.126347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/03/2025] [Revised: 04/22/2025] [Accepted: 05/04/2025] [Indexed: 05/14/2025]
Abstract
Developing a selective colorimetric assay for fluoroquinolones (FQs) that show visible color response is highly desired, which is challenging because FQs show extremely similarity in structure and inherently absorb light in the UV color range. In this work, a selective colorimetric assay for pefloxacin (PEF) was fabricated through integrating two rection systems: the inhibition effects of PEF on the AChE-like activities of Al3+ decorated MOF-808 (MOF-808-Al) and the thiol-response oxidase-mimicking reaction of MnO2 nanosheets. The MnO2 nanosheets, due to their oxidase-mimicking properties, can oxidize the colorless 3, 3', 5, 5'-tetramethylbenzidine (TMB) into its blue-colored oxidized form, TMB+. Assisted by the synergistic action of metal-OH and Lewis acid sites, MOF-808-Al exhibits AChE-like activities. These activities catalyze the decomposition of acetylthiocholine into thiocholine. Thiocholine has a stronger reactivity compared to TMB; it can reduce the MnO2 nanosheets, which in turn prevents the color response. In addition, PEF inhibits the AChE-like activities of MOF-808-Al by blocking its active sites. The quantitative detection of PEF is accomplished by recording the blue color response of the system, both in buffer solutions and in commercial meat samples. This assay demonstrates excellent tolerance and selectivity against various interfering substances, antibiotics, and pesticides.

Abstract
Accurate detection of tetracycline residue is of great significance for ensuring product quality and protecting human health. Here, a colorimetric/fluorescent dual-mode biosensor was developed for the detection of tetracycline in honey by using metalloporphyrin [TCPP(Fe)] covalently modified NH2-MIL-101(Fe) [named NH2-MIL-101(Fe)@TCPP(Fe)]. The morphology, chemical structure and peroxidas-like activity of this hybrid nanozyme were comprehensively studied. Based on excellent catalytic activity and intrinsic fluorescence of NH2-MIL-101(Fe)@TCPP(Fe), a colorimetric/fluorescent dual-mode biosensor was developed for the detection of tetracycline. The primary mechanism for this dual mode biosensor was the inhibitory effect of tetracycline on on NH2-MIL-101(Fe)@TCPP(Fe) catalyzed chromatic reaction between H2O2 and 3,3',5,5'-tetramethylbenzidine (TMB)/o-phenylenediamine (OPD), which was ascribed to the consumption of ·OH by tetracycline and the adsorption of tetracycline on the surface of NH2-MIL-101(Fe)@TCPP(Fe). After effective validation, this colorimetric/fluorescent dual mode method was applied to detect tetracycline residues in three actual honey samples.

Abstract
As food antioxidants are known deactivators of reactive species that may cause oxidative hazard, antioxidant capacity determination has gained importance in biochemistry, medicine and food science. In this study, a simple and sensitive dual-mode system based on spectrophotometric (SP) and spectrofluorometric (SF) determination of food antioxidants was developed using the Cu(II) complex of fluorescent bathocuproine sulfonate disodium salt (BCDS). In the proposed SF assay of total antioxidant capacity (TAC), a linear decrease in fluorescence occurs related to the formation of non-fluorescent Cu(I)-BCDS chelate depending on antioxidant concentration. At the same time in the SP method, the chemical reduction of Cu(II)-BCDS complex by antioxidants reflected in the absorbance increase of the formed Cu(I)-BCDS complex is monitored. By optimizing the optimal experimental conditions of the developed methods and applying them to standard antioxidant compounds separately, calibration equations were obtained and Trolox Equivalent Antioxidant Capacity (TEAC) values were calculated. The LOD values for Trolox obtained by SP and SF methods were found to be 0.16 and 5.08 μmolL-1, respectively. The sensitivity and accuracy of these two systems were examined by spiking known amounts of antioxidants to complex sample matrices. Both methods were successfully applied to the determination of TAC in food extracts. This dual sensing system is novel in view of the fact that the same probe (Cu(II)-BCDS) is used in the simple, rapid and sensitive determination of the same analyte (TAC) in two different (SP and SF) modes.

Abstract
Pathogenic bacteria, such as Pseudomonas aeruginosa, pose significant threats to public health due to their multidrug resistance and association with severe infections. Rapid and reliable detection methods are crucial for timely treatment and effective infection control, especially in resource-limited settings. In this study, we developed a CRISPR/Cas12a-based colorimetric biosensor that leverages Cas12a's trans-cleavage activity to release left single-stranded DNA (lDNA). The released lDNA facilitates hybridization with clDNA-functionalized gold nanoparticles (AuNPs), resulting in a visible color change. The biosensor achieved a detection limit of 100 CFU/reaction for P. aeruginosa within 2 hours, with excellent specificity and robustness, as validated in spiked sputum and blood samples. Clinical testing using 32 blood samples (13 positive, 19 negative) confirmed its high diagnostic accuracy, achieving an AUC of 1 in ROC curve analysis. The platform's simplicity, robustness, and programmability suggest its broad potential for rapid infectious disease diagnostics, particularly in low-resource settings.

Abstract
Hydrogen peroxide (H2O2) is an important intracellular reactive oxygen species that participates in a variety of life activities as a second messenger, especially as a pro-inflammation marker. Chemiluminescence is currently an ideal chemical tool for detecting biological substances, with the advantages of excellent signal-to-noise ratio and free autofluorescence interference, which is a cutting-edge science and technology for life sciences research. Herein, we report the design and evaluation of a novel chemiluminescent probe embedding a pentafluorobenzenesulfonyl ester group as a recognition moiety in a dioxetane skeleton. The results of imaging in living cells indicate that probe 4 (in 5 proposed probes) possesses high sensitivity, good selectivity, and the lowest limit of detection toward exogenous and endogenous H2O2 (LOD = 0.511 nM) compared with all the reported probes. It especially demonstrates excellent recognition performance in distinguishing between ONOO- and H2O2. Additionally, probe 4 shows low cytotoxicity and good biocompatibility, which performs highly specific and accurate imaging in the acute colitis mouse model. Taken together, this work reports a chemiluminescent probe for real-time monitoring of H2O2 dynamics in vitro and in vivo, which presents a reliable chemical tool for biosensing and disease diagnosis.

Abstract
Photoelectrochemical-colorimetric (PEC-CL) dual-mode detection integrates PEC and CL advantages for bioanalysis but often faces low efficiency, complex conditions, and performance trade-offs due to different signal transduction materials. Here, BiOI was functionalized by Bi0 self-doping and morphology engineering, forming a 3D Bi-doped BiOI nanoflower with excellent PEC and CL properties. This material was innovatively developed as a single transduction material for self-powered PEC-CL dual-mode detection. The synergistic enhancement of photoelectric conversion and peroxidase (POD)-like activity was systematically investigated. Using γH2AX, a genotoxicity biomarker, as a model, a self-powered PEC sandwich immunosensor was constructed with ITO/Au as the photocathode, BiOI-Ab2 as the signal probe, and CdIn2S4 as the photoanode. Upon γH2AX recognition, BiOI was introduced on the photocathode via an immunoreaction. The well-matched energy levels between Au and BiOI, along with the dual-photoelectrode effect, enable a sensitive "signal-on" PEC analysis. Simultaneously, a sandwich immunoreaction involving the BiOI-labeled secondary antibody occurred in the microplate containing H2O2 and 3,3',5,5'-tetramethylbenzidine (TMB), among which BiOI-catalyzed H2O2 produced reactive oxygen species, which further oxidized TMB to produce color, thus achieving the high-throughput visual detection of γH2AX. The PEC-CL dual-mode sensor exhibited broad linear ranges (0.1 pg/mL to 1000 ng/mL for PEC, 1 pg/mL to 500 ng/mL for CL) with ultralow detection limits of 23.9 and 330 fg/mL, respectively. The sensitivity of PEC mode is 100-fold higher than the ELISA method. Moreover, the practicability of the PEC-CL immunosensor was verified in cell lysates exposed to known genotoxic compounds. This sensing platform is versatile, which allows the detection of other biomarkers by changing the recognition element.

Abstract
BACKGROUND Cardiac troponin I (cTnI) is a crucial diagnosis biomarker for acute myocardial infarction (AMI). Early accurate determination of the concentration of cTnI significantly decreases the death rate of AMI. Compared with classic methods, dual-mode sensors for cTnI determination could help reduce the false positive rate. RESULT In this work, an ultrathin Fe-MOF-74 nanosheet with fluorescence properties and peroxidase mimic activity was synthesized for the first time. Applying this nanosheet, a novel dual-mode sensor was developed to quantify cTnI in human serum. The ultrathin Fe-MOF-74 nanosheets catalyze the decomposition of hydrogen peroxide produced by glucose oxidase (GOx)-triggered enzyme-linked immunosorbent assay (ELISA) applying cTnI as an antigen target, to generate reactive oxygen species (ROS). 3,3',5,5'-tetramethylbenzidine (TMB) can be oxidized by the generated free radicals, which simultaneously lead to the fluorescence quench of Fe-MOF-74 due to the inner filter effect (IFE). The correlation between the morphology of Fe-MOF-74 and its fluorescence intensity and peroxidase mimic activity was also investigated. SIGNIFICANCE The sensors exhibited linearity with the concentration of cTnI in 10-2000 pg mL-1 in both the fluorescence and visual mode with the detection limit of 6.4 pg mL-1 and 8.4 pg mL-1, respectively. It presenting good selectivity and anti-interference ability, can provide accurate and precise results in testing the concentration of cTnI in serum samples from patients in hospitals. It could be applied in the early diagnosis of AMI to reduce the incidence, disability, and mortality rates.

Abstract
The design of single-atom catalysts with dual functions has emerged as a promising strategy for developing high-performance sensing platforms. Herein, we reported a facile host-guest strategy for synthesizing an atomically dispersed Co catalyst (Co-N-C), where Co atoms were uniformly anchored on the N-doped carbon matrix derived from zeolitic imidazolate framework-8. The as-prepared Co-N-C exhibits both excellent electrochemical sensing and peroxidase-like colorimetric activities toward the detection of three important bioactive small molecules, ascorbic acid (AA), dopamine (DA), and uric acid (UA). The electrochemical sensor demonstrated ultrahigh sensitivity with detection limits of 4.83, 1.36, and 0.371 μM for AA, DA, and UA, respectively, along with outstanding selectivity against common interferents and stable performance. Meanwhile, the colorimetric method also showed analytical performance with detection limits of 2.24 μM (AA), 3.09 μM (DA), and 2.97 μM (UA). The results indicate that the electronic modulation of Co through precise nitrogen coordination enhances the affinity of Co-Nx for target reactants, thereby promoting adsorption and electron transfer throughout the reaction. This improves catalytic efficiency and selectivity, establishing Co-N-C with dual-catalytic functionality as a promising material for biosensing applications.

Abstract
Endotoxins are found in the outer membrane of all gram-negative bacteria and are a primary cause of endotoxemia, organ failure, and significant harm to human health. Limulus reagent as traditional detection method has certain limitations for the rapid and accurate detection of endotoxin due to the high costs associated with the horseshoe crab used in the sensing process. Herein, a fluorometric and colorimetric dual-mode biosensor was prepared for the rapid and sensitive detection of endotoxin. The chitosan-grafted Fe,Cu-doped carbon dots (CDs) was used to reduce KMnO4 to produce CS@Fe,Cu/CDs-MnO2, which demonstrated distinctive characteristics including high catalytic activity as an artificial nanozyme and a fluorescence quantum yield of 76 %. On the one hand, CS@Fe,Cu/CDs-MnO2 with the peroxidase-like activity and positively charged property can oxidize 3,3-diaminobenzidine tertrahydrochloride (DAB) and H2O2 to yield a brown product (oxDAB). Additionally, it can interact with negatively charged endotoxin through electrostatic forces, which leads to a reduction in its nanozyme catalytic activity. On the other hand, oxDAB can quench the CS@Fe,Cu/CDs-MnO2 fluorescence via inner-filter effect and static quenching. Therefore, a dual-mode biosensor that utilizes both fluorescence and colorimetric methods is developed with the aid of a smartphone. It was found that the gray value of absorbance increased linearly with endotoxin concentration in the range of 0.125-175 EU/L with a minimum limit of detection (LOD) of 0.058 EU/L, while the gray value of fluorescence intensity also demonstrated a linear increase upon the addition of endotoxin within the range of 0.05-90 EU/L with a LOD of 0.036 EU/L. The sensor is effectively utilized for detecting endotoxin in real injection samples, achieving acceptable recovery rates between 89.0 % and 101.3 %, with a relative standard deviation (RSD) of no more than 4.51 %. This indicates the reliability of the fabricated biosensor.

Abstract
Conventional immunochromatography (ICA) using a single-signal output mode suffers from poor sensitivity, narrow detection range, and susceptibility to external interference. The rational development of multifunctional tags is a promising strategy for integrated multimodal ICA. Herein, this study reports on multimodal ICA using "all-in-one" 2D multifunctional polygonal nanoparticles (CPPs). The spectral absorption capacity of CPPs and excellent photothermal properties (η = 89.9%) ensure the high sensitivity of ICA. The good catalytic ability enables ICA to guarantee high sensitivity while taking into account a wide detection range (expanded by about 1.5 times). Based on spectral overlap, fluorescence calibration is performed in low background to improve the practicability of ICA. The detection range of the multimodal CPPs-ICA for vomitoxin (DON) is 0.01-60 ng/mL, with the lowest qualitative and quantitative results of 0.5 and 0.021 ng/mL, respectively. This multimodal CPPs-ICA platform is expected to be an instant detection platform for multifunctional application scenarios.

Abstract
D2O and H2O, as two important solvents with very similar properties, play a pivotal role in nuclear industrial production, life and scientific research. Unfortunately, D2O and H2O are highly susceptible to contamination by each other, so effective qualitative and quantitative analyses of both are necessary. This review comprehensively discusses the progress in optical sensing for the detection of a trace amount of H2O in heavy water or vice versa, mainly including five types of analytical systems: inorganic nanocrystals, carbon-based nanomaterials, lanthanide complexes, organic polymers, and organic small molecules. The whole article is divided into several sub-sections based on multiple mechanisms underlying the design of heavy water optical sensors, i.e., the difference in binding energy, the difference in quenching efficacy of oscillator types and the difference in acid-base of H2O and D2O. The working mechanism, advantages and disadvantages, analytical performance and applications of the reported sensors in recent years were analyzed in detail, and the future development is envisioned for the optical sensors towards distinguishing D2O and H2O.

Abstract
Food safety is severely burdened by the prevalence of foodborne pathogens and the diseases they cause, necessitating the development of rapid, easy-to-use, highly sensitive, and reliable detection methods. Here, a signal-off colorimetric and signal-on fluorometric dual-mode detection method for Salmonella Typhimurium (S. typhimurium) was developed based on its unique interaction with aptamer DNA and graphitic carbon nitride (GCN). In the absence of a target Salmonella species, 6-carboxyfluorescein (FAM)-labeled aptamers are adsorbed on the surface of GCN primarily via a π-π interaction, resulting in reduced fluorescence of FAM through GCN-mediated quenching as well as improved peroxidase-like activity of GCN to generate intense blue color through facilitated electrostatic attraction between the negatively charged aptamer and positively charged 3,3',5,5'-tetramethylbenzidine (TMB) substrate. The introduction of S. typhimurium to the sample solution causes the detachment of the aptamer from GCN due to its higher affinity for S. typhimurium than GCN, thereby rapidly reducing the colorimetric signal and recovering the fluorescence. We successfully determined the number of S. typhimurium using this method in a remarkably short duration (10-30 min), highlighting its rapidity. The limit of detection values for S. typhimurium were as low as 8 and 3 CFU/mL when using colorimetric and fluorometric methods, respectively. Moreover, this method can be used to detect S. typhimurium spiked in real vegetable extract and milk with high reproducibility and reliability. This method serves as a convenient route to the rapid, sensitive, selective, and reliable detection of pathogens from complex food samples, with the potential to replace conventional yet laborious methods currently in use.

Abstract
An innovative method for carbendazim (CBZ) detection was developed, consisting of an electrochemical-fluorescence dual-mode biosensor based on magneto-fluorescent composite M-CDs. M-CDs, as the fluorescent probe of this sensor, could combine the electrical signal-ferrocene to achieve the "signal switching" by specifically recognizing CBZ through aptamers, of which magnetic property was used to quickly separate from complex substrates without interference. The dual-mode sensor based on M-CDs demonstrated excellent linear responses in both electrochemical and fluorescence assays. It achieved detection ranges of 10 fg/mL - 300 ng/mL and 60 fg/mL - 100 ng/mL with detection limits (LODs) of 1.4 fg/mL and 2.3 fg/mL. The sensor exhibited exceptional detection performance, stability and anti-interference. In addition, the results of the sensor in actual samples were consistent with those of enzyme-linked immunosorbent assay (ELISA), which further demonstrated that the sensor could accurately trace detecting CBZ in real samples and had a certain application prospect.

Abstract
The wide use and high toxicity of carbendazim (CBD) in agriculture pose unprecedented demands for convenient, sensitive, and cost-effective on-site monitoring. Herein, we propose a novel colorimetric and photothermal dual-mode lateral flow immunoassay (LFIA) based on plasmonic gold nanostars (AuNSs) for CBD detection in agricultural products. The AuNSs were synthesized via a rapid seed-mediated growth method (with growth time of ∼5 s). A stable immunoprobe was formed by adsorbing CBD antibodies onto AuNSs. This immunoprobe exhibited high conversion efficiency and sensitivity in photothermal detection with a low limit of detection (LOD) of 0.28 ng mL-1. The LOD of the colorimetric mode was higher (0.48 ng mL-1). The results of CBD detection in various agricultural products aligned well with ultra-performance liquid chromatography tandem mass spectrometry. Overall, our LFIA shows excellent sensitivity, specificity, reproducibility, and rapidness in CBD detection, and thus is a highly potential on-site platform in resource-limited environments.

Abstract
BACKGROUND Bisphenol A (BPA) has been identified as an endocrine disruptor with numerous detrimental effects on human health. There is an urgent need to develop fluorescence/colorimetric dual-mode sensing approaches with expanded detection linear range, increased accuracy, and enhanced application flexibility for BPA detection. The utilization of fluorescence and colorimetric signals in point-of-care applications and real-time sensitive sensing further highlights the significance of developing novel and efficient fluorescence/colorimetric dual-mode sensing platform with high-efficiency probes. RESULTS Herein, a fluorescence and colorimetric dual-mode aptasensor was developed by using CsPbBr3@Cu-MOF as the aptamer immobilization matrix and signal generator. CsPbBr3 was functionalized with Cu-MOF using a simple two-step strategy. This strategy involved in-situ formation and modified ligand-assisted precipitation technique with 4,4'-bipyridine (4,4-Bpy) serving as the bifunctional linker. The resulting CsPbBr3@Cu-MOF exhibited improved stability in water and enhanced fluorescence. Additionally, it functioned as peroxidase mimetic to oxidize 3,3',5,5'-tetramethyl benzidine (TMB), leading to a colorimetric change from colorless to blue. In the presence of BPA, aptamers were removed from CsPbBr3@Cu-MOF. Consequently, the fluorescence and peroxidase-activity of CsPbBr3@Cu-MOF were recovered, resulting in the enhanced fluorescence intensity and color change of TMB. Using this system, the proposed aptasensor demonstrated detection ranges of 1.0-80.0 nM with a LOD of 0.60 nM for the colorimetric method, and a linearity range of 0.1-100 nM with a LOD of 0.02 nM for the fluorescence method. SIGNIFICANCE The obtained CsPbBr3@Cu-MOF composites showed excellent fluorescence properties, good peroxidase-like activity, and aqueous stability. Furthermore, the proposed dual-mode aptasensor demonstrated simplicity, cost-effectiveness and good anti-interference abilities. This can be extended to the construction of other dual-mode sensors by changing aptamers and provides novel insights on the potential applications of perovskites in bioanalysis.

Abstract
BACKGROUND Aptasensors have been extensively utilized in target detection due to their advantages of high sensitivity and fast response. However, the reliability of the detection results of the single-mode aptasensor cannot be verified in time. Developing efficient detection methods with cross-validation capability is beneficial to achieving highly reliable detection. This study aims to design a colorimetric and fluorescent dual-mode aptasensor by skillfully engineering G-quadruplex assembly and rolling circle amplification for highly reliable IFN-γ detection. RESULTS The complexes of anti-IFN-γ aptamers and complement sequences (cDNA) were modified on the magnetic beads. In the presence of IFN-γ, the preferential combination of aptamers with IFN-γ resulted in the release of cDNAs. The cDNAs were collected by magnetic separation and then used as primers to trigger rolling circle amplification reaction to generate enriched G-quadruplexes. The G-quadruplex could be utilized to combine with hemin to catalyze the oxidation of 3,3',5,5'-tetramethylbenzidine for colormetric mode or to couple with the fluorogenic dye Thioflavin T for fluorescent mode. The developed dual-mode aptasensor displayed a linear range of 1-10000 pM with a detection limit of 0.406 pM for the colormetric mode and a range of 0.1-10000 pM with a detection limit of 0.037 pM for the fluorescent mode. Further, the designed aptasensor was applied to IFN-γ detection in serum samples and achieved satisfactory recoveries. SIGNIFICANCE This innovative dual-mode detection strategy skillfully leverages the effective target-binding ability of aptamer, dual-function of the G-quadruplex and the signal amplifying ability of rolling circle amplification. This approach not only provides a reliable testing tool for the detection of IFN-γ, but also promotes the development of multimode sensing platforms.

Abstract
The intracellular levels of biothiols are associated with various diseases including cancer, and biothiols are regarded as tumor biomarker. Due to the similarity of the molecular structure of biothiols, the development of simple, rapid, efficient, and sensitive colorimetric sensor arrays holds great promise for clinical cancer diagnosis. Here, we developed a simple Ag-MoS2 hybrid nanozyme-based sensor array for colorimetric identification of biothiols and cancer cells. The novel Ag-MoS2 nanoprobe was synthesized in a simple and efficient way through the in situ self-reduction reaction between MoS2 and noble metal precursor. Benefiting from to the formation of heterogeneous metal structures, the peroxidase (POD)-like catalytic activity of the synthesized Ag-MoS2 hybrid nanocomposites is significantly enhanced compared to MoS2 alone. Moreover, the catalytic activity of Ag-MoS2 nanozyme was correlated with the pH of the reaction solution and the inhibitory effects of the three biothiols on the nanozyme-triggered chromogenic system differed in the specific pH environments. Therefore, each sensing unit of this electronic tongue generated differential colorimetric fingerprints of different biothiols. After principal component analysis (PCA), the developed novel colorimetric sensor array can accurately discriminate biothiols between different types, various concentrations, and different mixture proportions. Further, the sensor array was used for the colorimetric identification of real serum and cellular samples, demonstrating its great potential in tumor diagnostic applications.

Non-pyrolytic synthesis of laccase-like iron based single-atom nanozymes for highly efficient dual-mode colorimetric and fluorescence detection of epinephrine. Anal Chim Acta 2024; 1322:343031. [PMID: 39182985 DOI: 10.1016/j.aca.2024.343031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2024] [Revised: 07/24/2024] [Accepted: 07/25/2024] [Indexed: 08/27/2024]
Abstract
Single-atom nanozymes have garnered significant attention due to their exceptional atom utilization and ability to establish well-defined structure-activity relationships. However, conventional pyrolytic synthesis methods pose challenges such as high energy consumption and random local environments at the active sites, while achieving non-pyrolytic synthesis of single-atom nanozymes remains a formidable technical hurdle. The present study focuses on the synthesis of laccase-like iron-based single-atom nanozymes (Fe-SAzymes) using a non-pyrolysis method facilitated by microwave irradiation. Under low iron loading conditions, Fe-SAzymes exhibited significantly enhanced laccase activity (12.1 U/mg), surpassing that of laccase by 24-fold. Moreover, Fe-SAzymes demonstrated efficient catalytic oxidation of epinephrine (EP), enabling its colorimetric detection. Owing to the remarkable laccase activity of Fe-SAzymes, the conventional nanozymes EP detection time was reduced from 60 min to 20 min, with an impressive low detection limit as low as 2.95 μM. In addition, an ultra-sensitive fluorescence method for EP detection was developed using the internal filter effect of EP oxidation products and CDs combined with carbon dots probe. The detection limit of fluorescence method was only 0.39 μM. Therefore, an visual, fast, and highly sensitive dual-mode EP detection strategy has great potential in the clinical diagnostic industry.

Abstract
Developing a simple, economical, sensitive, and selective method for label-free direct detection analytes is attractive, especially the strategies that could achieve signal amplification without complicated operations. Herein, a dual-fluorescence colorimetric nanoswitch sensing platform for label-free direct melamine (MEL) detection was established. We first explored the relationship between MEL-induced aggregation of gold nanoparticles (AuNPs) and size and determined the optimal size to be 37 nm. Using surfactant Triton X-100 to modify AuNPs and clarify possible interaction mechanisms to improve detection performance. The dynamic changes of surface plasmon resonance absorption peaks in the dispersed and aggregated states of AuNPs were skillfully utilized to match the emission of multicolor gold nanoclusters to trigger the multi-inner filter effect. Accompanied by the addition of MEL-induced AuNPs to change from dispersed to aggregated state, the fluorescence of green-emitting and red-emitting gradually turned on and turned off, respectively. The fluorescence turn-on mode detection limit was 10 times higher than the colorimetric method and as low as 5.5 ng/mL; the detection took only 10 min. The sensor detected MEL in spiked milk samples with a good recovery in the range of 81.2-111.0 % with a coefficient of variation less than 11.4 % and achieved a good correlation with commercial kits. The proposed sensor integrates numerous merits of label-free, multi-signal readout, self-calibration, simple operations, and economical, which provides a promising tool for convenient on-site detection of MEL.

Abstract
One of the biggest challenges in biotechnology and medical diagnostics is finding extremely sensitive and adaptable biosensors. Since metal-based enzyme-mimetic biocatalysts may lead to biosafety concerns on accumulative toxicity, it is essential to synthesize metal-free enzyme-mimics with optimal biocatalytic activity and superior selectivity. Here, the pyridine-bridged covalent organic frameworks (COFs) with specific oxidase-like (OXD-like) activities as intelligent artificial enzymes for light-augmented biocatalytic sensing of biomarkers are disclosed. Because of the adjustable bandgaps of pyridine structures on the photocatalytic properties of the pristine COF structures, the pyridine-bridged COF exhibit efficient, selective, and light-responsive OXD-like biocatalytic activity. Moreover, the pyridine-bridged COF structures show tunable and light-augmented biocatalytic detection capabilities, which outperform the recently reported state-of-the-art OXD-mimics regarding biosensing efficiency. Notably, the pyridine-bridged COF exhibits efficient and multifaceted diagnostic activity, including the extremely low limit of detection (LOD), which enables visual assays for abundant reducibility biomarkers. It is believed that this design will offer unique metal-free biocatalysts for high-sensitive and low-cost colorimetric detection and also provide new insights to create highly efficient enzyme-like COF materials via linkage-modulation strategies for future biocatalytic applications.

Abstract
Dopamine (DA), a neurotransmitter, plays a crucial role in regulating motor functions and emotions and can serve as a marker for several diseases. In this study, we report a highly sensitive polydiacetylenes (PDA)-based dual-output sensor for dopamine detection in both solution and solid phases that was developed by modifying PDA liposomes with boronic acid groups at the termini. This sensor exploits the high affinity between the catechol residue of dopamine and the -B(OH)2 group of the PDA-based probe (PDA-PhBA) to form boronate ester bonds, causing a stress-induced blue-to-red color change along with a steady increase in fluorescence response at λmax 622 nm. The PDA-PhBA-based sensor displays high sensitivity toward dopamine with low limit of detection of 6.2 ppb in colorimetric analysis and 0.6 ppb in fluorimetric measurements, demonstrating its dual optical output ability. The sensor works well for adrenaline, another catecholamine, with similar efficacy. Its practical applicability was validated by the successful recovery of trace level dopamine in blood serum and real water samples. Additionally, immobilizing PDA-PhBA liposomes in sodium alginate produced PDA beads for the solid-phase detection of dopamine with an limit of detection (LOD) of 59 nM (9.0 ppb) in colorimetric detection using a smartphone for capturing images and ImageJ software for analysis.

Abstract
Biosensors are currently among the most commonly used devices for analysing biomarkers and play an important role in environmental detection, food safety, and disease diagnosis. Researchers have developed multimodal biosensors instead of single-modal biosensors to meet increasing sensitivity, accuracy, and stability requirements. Metal nanoparticles (MNPs) are beneficial for preparing core probes for multimodal biosensors because of their excellent physical and chemical properties, such as easy regulation and modification, and because they can integrate diverse sensing strategies. This review mainly summarizes the excellent physicochemical properties of MNPs applied as biosensing probes and the principles of commonly used MNP-based multimodal sensing strategies. Recent applications and possible improvements of multimodal biosensors based on MNPs are also described, among which on-site inspection and sensitive detection are particularly important. The current challenges and prospects for multimodal biosensors based on MNPs may provide readers with a new perspective on this field.

Abstract
Detection of circulating tumor DNA (ctDNA) in liquid biopsy is of great importance for tumor diagnosis but difficult due to its low amount in bodily fluids. Herein, a novel ctDNA detection platform is established by quantifying DNA amplification by-product pyrophosphate (PPi) using a newly designed bivariable lanthanide metal-organic framework (Ln-MOF), namely, Ce/Eu-DPA MOF (CE-24, DPA = pyridine-2,6-dicarboxylic acid). CE-24 MOF exhibits ultrafast dual-response (fluorescence enhancement and enzyme-activity inhibition) to PPi stimuli by virtue of host-guest interaction. The platform is applied to detecting colon carcinoma-related ctDNA (KARS G12D mutation) combined with the isothermal nucleic acid exponential amplification reaction (EXPAR). ctDNA triggers the generation of a large amount of PPi, and the ctDNA quantification is achieved through the ratio fluorescence/colorimetric dual-mode assay of PPi. The combination of the EXPAR and the dual-mode PPi sensing allows the ctDNA assay method to be low-cost, convenient, bioreaction-compatible (freedom from the interference of bioreaction systems), sensitive (limit of detection down to 101 fM), and suitable for on-site detection. To the best of our knowledge, this work is the first application of Ln-MOF for ctDNA detection, and it provides a novel universal strategy for the rapid detection of nucleic acid biomarkers in point-of-care scenarios.

Abstract
Determination of dopamine (DA) is crucial for its intimate relationship with clinical trials and biological environment. Herein, Fe, N co-doped carbon dots (AFC-CDs) were fabricated by optimizing precursors and reaction conditions for fluorimetric/colorimetric dual-mode sensing of DA. With synergistic influence of Förster resonance energy transfer and static quenching effect, DA significantly quenched the blue luminescence of AFC-CDs at 442 nm, the production of recognizable tan-brown complex caused evident colorimetric response, achieved the dual-mode fluorimetric/colorimetric sensing for DA. The excellent selectivity and satisfied sensitivity can be confirmed with the limit of detection at 0.29 μM and 2.31 μM via fluorimetric/colorimetric mode respectively. The reliability and practicability were proved by recovery of 94.81-101.61% in real samples. Notably, the proposed electron transfer way between AFC-CDs and DA was hypothesized logically, indicated dual-mode probe provided a promising platform for the sensing of trace DA, and could be expanded in environment and food safety.

Abstract
The traditional lateral flow immunoassay (LFIA) with a single signal output mode may encounter challenges such as low sensitivity, poor detection range, and susceptibility to external interferences. These limitations hinder its ability to meet the growing demand for advanced LFIA. To address these issues, the rational development of multifunctional labels for multimodal LFIA emerges as a promising strategy. Herein, this study reports a multimodal LFIA using "four-in-one" multifunctional dandelion-like gold@platinum nanoparticles (MDGP). The inherent properties of MDGP, such as the broad absorption spectrum, porous dandelion-like nanostructure, and bimetallic composition with gold and platinum, endow them with capacities in dual spectral-overlapped fluorescence quenching, optical readout, catalytic activity, and photothermal effect. Benefiting from their multifunctional properties, the MDGP-LFIA enables multimodal outputs including fluorescent, colorimetric, and photothermal signals. This multimodal MDGP-LFIA allows for the detection of acetamiprid at a range of 0.01-50 ng mL-1, with the lowest qualitative and quantitative detection results of 0.5 and 0.008 ng mL-1, respectively, significantly better than the traditional gold nanoparticles-based LFIA. The diversity, complementarity, and synergistic effect of integrated output signals in this multimodal MDGP-LFIA improve the flexibility, practicability, and accuracy of detection, holding great promise as a point-of-care testing platform in versatile application scenarios.

Bridging biological and food monitoring: A colorimetric and fluorescent dual-mode sensor based on N-doped carbon dots for detection of pH and histamine. JOURNAL OF HAZARDOUS MATERIALS 2024; 470:134271. [PMID: 38608593 DOI: 10.1016/j.jhazmat.2024.134271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 03/30/2024] [Accepted: 04/09/2024] [Indexed: 04/14/2024]
Abstract
Rapid and sensitive monitoring of pH and histamine is crucial for bridging biological and food systems and identifying corresponding abnormal situations. Herein, N-doped carbon dots (CDs) are fabricated by a hydrothermal method employing dipicolinic acid and o-phenylenediamine as precursors. The CDs exhibit colorimetric and fluorescent dual-mode responses to track pH and histamine variations in living cells and food freshness, respectively. The aggregation-induced emission enhancement and intramolecular charge transfer result in a decrease in absorbance and an increase in fluorescence, which become readily apparent as the pH changes from acidic to neutral. This property enables precise differentiation between normal and cancerous cells. Furthermore, given the intrinsic basicity of histamine, pH-responsive CDs are advantageous for additional colorimetric and fluorescent monitoring of histamine in food freshness, achieving linearities of 25-1000 µM and 30-1000 µM, respectively, which are broader than those of alternative nanoprobes. Interestingly, the smartphone-integrated sensing platform can portably and visually evaluate pH and histamine changes due to sensitive color changes. Therefore, the sensor not only establishes a dynamic connection between pH and histamine for the purposes of biological and food monitoring, but also presents a novel approach for developing a multifunctional biosensor that can accomplish environmental monitoring and biosensing simultaneously.

Abstract
Nanomaterials show great potential for applications in biosensing due to their unique physical, chemical, and biological properties. However, the single-modal signal sensing mechanism greatly limits the development of single-modal nanoprobes and their related sensors. Multi-modal nanoprobes can realize the output of fluorescence, colorimetric, electrochemical, and magnetic signals through composite nanomaterials, which can effectively compensate for the defects of single-modal nanoprobes. Following the multi-modal nanoprobes, multi-modal biosensors break through the performance limitation of the current single-modal signal and realize multi-modal signal reading. Herein, the current status and classification of multi-modal nanoprobes are provided. Moreover, the multi-modal signal sensing mechanisms and the working principle of multi-modal biosensing platforms are discussed in detail. We also focus on the applications in pharmaceutical detection, food and environmental fields. Finally, we highlight this field's challenges and development prospects to create potential enlightenment.

Abstract
Wearable devices have become prevalent in biomedical studies due to their convenient portability and potential utility in biomarker monitoring for healthcare. Accessing interstitial fluid (ISF) across the skin barrier, microneedle (MN) is a promising minimally invasive wearable technology for transdermal sensing and drug delivery. MN has the potential to overcome the limitations of conventional transdermal drug administration, making it another prospective mode of drug delivery after oral and injectable. Subsequently, combining MN with multiple sensing approaches has led to its extensive application to detect biomarkers in ISF. In this context, employing MN platforms and control schemes to merge diagnostic and therapeutic capabilities into theranostic systems will facilitate on-demand therapy and point-of-care diagnostics, paving the way for future MN technologies. A comprehensive analysis of the growing advances of microneedles in biomedical systems is presented in this review to summarize the latest studies for academics in the field and to offer for reference the issues that need to be addressed in MN application for healthcare. Covering an array of novel studies, we discuss the following main topics: classification of microneedles in the biomedical field, considerations of MN design, current applications of microneedles in diagnosis and therapy, and the regulatory landscape and prospects of microneedles for biomedical applications. This review sheds light on the significance of microneedle-based innovations, presenting an analysis of their potential implications and contributions to the community of wearable healthcare technologies. The review provides a comprehensive understanding of the field's current state and potential, making it a valuable resource for academics and clinicians seeking to harness the full potential of MN applications.

Abstract
BPA aptamers functionalized cerium oxide nanoparticles encapsulated in zeolitic imidazolate framework-8 (CeO2@ZIF-8/Apt) were developed to fabricate an all-in-one portable platform for on-site quantitative detection of BPA. By combining biocomposites with a 3,3',5,5'-tetramethylbenzidine (TMB)-based sodium alginate (SA) hydrogel and smartphone-based RGB analysis, highly sensitive and convenient monitoring of BPA was achieved. CeO2@ZIF-8 composites were constructed using a novel surfactant-modified concentration-controlled synthesis strategy. After being functionalized with BPA aptamers, CeO2@ZIF-8/Apt biocomposites were used as target-response colorimetric probes for target recognition and signal transduction. The oxidase-like activity of CeO2@ZIF-8 was effectively sealed by BPA aptamers and controllably released in a concentration-dependent manner through aptamer-BPA reactions. Utilizing SA hydrogels containing TMB in the caps, a one-step sample addition and one-pot detection can be conveniently achieved and reliably quantified by smartphone-based RGB analysis in an instrument-free way. The detection range of this portable detection platform is 50 pg/mL to 500 ng/mL with limit of detection calculated as 34.88 pg/mL, comparable to that of conventional detection in the solution system (4.57 pg/mL). The recoveries in tap water, apple juice, and milk ranged from 91.02 % and 106.75 %. This work contributes new insights into the design of all-in-one detection platforms for contaminants monitoring in resource-constrained regions.

Abstract
The quality of life of patients affected by Parkinson's disease is improved by medications containing levodopa and carbidopa, restoring the dopamine concentration in the brain. Accordingly, the affordable quality control of such pharmaceuticals is very important. Here is reported the simple and inexpensive colorimetric quantification of carbidopa in anti-Parkinson drugs by the selective condensation reaction between the hydrazine group from carbidopa and the formyl functional group of selected aldehydes in acidified hydroalcoholic solution. An optical assay was developed by using indole-3-carbaldehyde (I3A) giving a yellow aldazine in EtOH:H2O 1:1 (λmax~415 nm) at 70 °C for 4 h, as confirmed by LC-MS analysis. A filter-based plate reader was used for colorimetric data acquisition, providing superior results in terms of analytical performances for I3A, with a sensitivity ~50 L g-1 and LOD ~0.1 mg L-1 in comparison to a previous study based on vanillin, giving, for the same figures of merit values, about 13 L g-1 and 0.2-0.3 mg L-1, respectively. The calibration curves for the standard solution and drugs were almost superimposable, therefore excluding interference from the excipients and additives, with very good reproducibility (avRSD% 2-4%) within the linear dynamic range (10 mg L-1-50 mg L-1).

Abstract
Credible and on-site detection of organophosphorus pesticides (OPs) in complex matrixes is significant for food security and environmental monitoring. Herein, a novel COF/methylene blue@MnO2 (COF/MB@MnO2) composite featured abundant signal loading, a specific recognition unit, and robust oxidase-like activity was successfully prepared through facile assembly processes. The multifunctional composite acted as a homogeneous electrochemical and photothermal dual-mode sensing platform for OPs detection through stimuli-responsive regulation. Without the presence of OPs, the surface MnO2 coating could recognize thiocholine (TCh), originating from acetylcholinesterase (AChE)-catalyzed hydrolysis of acetylthiocholine (ATCh), and exhibited a distinctly amplified diffusion current due to the release of plentiful MB; while the residual MnO2 nanosheets could only catalyze less TMB into oxidized TMB (oxTMB) with a typical near-infrared (NIR) absorption, enabling NIR-driven photothermal assay with a low temperature using a portable thermometer. Based on the inhibitory effect of OPs on AChE activity and OP-regulated generation of TCh, chlorpyrifos as a model target can be accurately detected with a low limit of detection of 0.0632 and 0.108 ng/mL by complementary electrochemical and photothermal measurements, respectively. The present dual-mode sensor was demonstrated to be excellent for application to the reliable detection of OPs in complex environmental and food samples. This work can not only provide a complementary dual-mode method for convenient and on-site detection of OPs in different scenarios but also expand the application scope of the COF-based multifunctional composite in multimodal sensors.

Abstract
Reactive sulfur species (RSS) are emerging as a potential key gasotransmitter in diverse physiological processes linking two signaling molecules H2S and SO2. However, the exact roles of H2S and SO2 remain unclear. A major hurdle is the shortage of accurate and robust approaches for sensing of H2S and SO2 in biological systems. Herein, we report a reaction-mediated dual-recognition strategy-based nanosensor, silver nanoparticles (AgNPs)-loaded MIL-101 (Fe) (ALM) hybrids, for the simultaneous detection of H2S and SO2 in a living cell. Upon exposure to H2S, AgNPs can be oxidized to form Ag2S, causing a decrease of surface enhanced Raman spectroscopy (SERS) signals of p,p'-dimercaptoazobenzene. Moreover, SO2 reacts with the amino moiety of MIL-101 to form charge-transfer complexes, resulting in an increment of fluorescent (FL) intensity. The ALM with dual-modal signals can simultaneously analyze H2S and SO2 at a concentration as low as 2.8 × 10-6 and 0.003 μM, respectively. Most importantly, the ALM sensing platform enables targeting mitochondria and detection multiple RSS simultaneously in living cells under external stimulation, as well as displays indiscernible crosstalk between SERS and FL signals, which is very beneficial for the comprehension of physiological issues related with RSS.

Abstract
Plasmonic nanomaterials have attracted great attention in the field of catalysis and sensing for their outstanding electrical and optical properties. Here, a representative type of nonstoichiometric Cu2-xSe nanoparticles with typical near-infrared (NIR) localized surface plasma resonance (LSPR) properties originating from their copper deficiency was applied to catalyze the oxidation of colorless TMB into their blue product in the presence of H2O2, indicating they had good peroxidase-like activity. However, glutathione (GSH) inhibited the catalytic oxidation of TMB, as it can consume the reactive oxygen species. Meanwhile, it can induce the reduction of Cu(II) in Cu2-xSe, resulting in a decrease in the degree of copper deficiency, which can lead to a reduction in the LSPR. Therefore, the catalytic ability and photothermal responses of Cu2-xSe were decreased. Thus, in our work, a colorimetric/photothermal dual-readout array was developed for the detection of GSH. The linear calibration for GSH concentration was in the range of 1-50 μM with the LOD as 0.13 μM and 50-800 μM with the LOD as 39.27 μM. To evaluate the practicability of the assay, tomatoes and cucumbers were selected as real samples, and good recoveries indicated that the developed assay had great potential in real applications.

Abstract
We presented a colorimetric/fluorescent dual-mode immunochromatographic assay (ICA) for the sensitive detection of Escherichia coli O157:H7. The use of polydopamine (PDA)-modified gold nanoparticles (AuNPs) with broadband absorption allowed for excellent colorimetry signals for the ICA detection. Moreover, the absorption spectrum of PDA-AuNPs significantly overlaps with the excitation and emission spectra of ZnCdSe/ZnS quantum dots (QDs), resulting in effective quenching of the QDs fluorescence due to the inner filter effect. The fluorescence intensity changes induced by PDA-AuNPs were utilized for the sensitive detection of E. coli O157:H7, achieving a detection limit of 9.06 × 101 CFU/mL, which was 46-fold lower than that of traditional AuNPs-based immunoassay. The proposed immunosensor exhibited the recovery rate between 80.12% and 114.69% in detecting actual samples, indicating its reliability and satisfactory accuracy. This study provides insights into dual-mode signal outputs and the ICA development for food safety applications.

MICROMACHINES 2023; 14:mi14050902. [PMID: 37241526 DOI: 10.3390/mi14050902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 04/18/2023] [Accepted: 04/20/2023] [Indexed: 05/28/2023]
Abstract
A highly sensitive and accurate dual-signal strategy is developed for trace Cu2+ detection based on the inner filter effect (IFE) between Tween 20-gold nanoparticles (AuNPs) and CdSe/ZnS quantum dots (QDs). Tween 20-AuNPs are utilized as colorimetric probes and excellent fluorescent absorbers. The fluorescence of CdSe/ZnS QDs can be quenched efficiently by Tween 20-AuNPs via IFE. In the presence of D-penicillamine, D-penicillamine induces the aggregation of Tween 20-AuNPs and the fluorescent recovery of CdSe/ZnS QDs at high ionic strength. Upon addition of Cu2+, D-penicillamine tends to selectively chelate with Cu2+ and then forms the mixed-valence complexes, which consequently inhibits the aggregation of Tween 20-AuNPs and the fluorescent recovery. The dual-signal method is used to quantitatively detect trace Cu2+, with low detection limits of 0.57 μg/L and 0.36 μg/L for colorimetry and fluorescence, respectively. In addition, the proposed method using a portable spectrometer is applied to the detection of Cu2+ in water. This sensitive, accurate and miniature sensing system has potential in environmental evaluations.

Abstract
We used the first enzyme-free synthesis and stabilization of soluble melanochrome (MC) and 5,6-indolequinone (IQ) derived from levodopa (LD), dopamine (DA), and norepinephrine (NE) oxidation to develop a simple colorimetric assay for catecholamine detection in human urine, also elucidating the time-dependent formation and molecular weight of MC and IQ using UV-Vis spectroscopy and mass spectrometry. The quantitative detection of LD and DA was achieved in human urine using MC as a selective colorimetric reporter to demonstrate the potential assay applicability in a matrix of interest in therapeutic drug monitoring (TDM) and in clinical chemistry. The assay showed a linear dynamic range between 5.0 mg L-1 and 50.0 mg L-1, covering the concentration range of DA and LD found in urine samples from, e.g., Parkinson's patients undergoing LD-based pharmacological therapy. The data reproducibility in the real matrix was very good within this concentration range (RSDav% 3.7% and 6.1% for DA and LD, respectively), also showing very good analytical performances with the limits of detection of 3.69 ± 0.17 mg L-1 and 2.51 ± 0.08 mg L-1 for DA and LD, respectively, thus paving the way for the effective and non-invasive monitoring of dopamine and levodopa in urine from patients during TDM in Parkinson's disease.

Abstract
Herein, three patterns for the detection of fenpyroximate based on the response signal of gold nanoparticles are described. The strong interaction between the guanidine group of arginine-modified gold nanoparticles and the ester group of fenpyroximate led to the aggregation of the nanoparticles and to a variation of ultraviolet-visible light spectrum and color of the solution. Sensors were constructed based on the correlation of the concentration of fenpyroximate with the absorbance ratio (A650/A525) and the R value was obtained by extracting the color of the test solution by using a smartphone to take a photo of the solution, which was then analyzed by colorimeter software. The absorbance ratio increased linearly in the range of 0.225-0.375 mg L-1 and the limit of detection was 0.215 mg L-1, while the R value declined linearly in the range of 0.20-0.40 mg L-1 and the limit of detection was 0.21 mg L-1. Further, the gold nanoparticles could cause a fluorescence quenching of fluorescent dyes, such as rhodamine B, and it was found that the fluorescence could be quenched and then restored after aggregation; therefore, a fluorescence method based on fluorescence "off-on" was constructed, and the fluorescence quenching was found to increase linearly in the range of 0.0-1.0 mg L-1 and the limit of detection was 0.013 mg L-1. These three patterns indicated highly selective and sensitive response signals for fenpyroximate, and all were applied to the detection of fenpyroximate in apple juice, pear juice, and environmental water samples, with the results showing that the three methods could be mutually verified, with the recoveries ranging from 94.15% to 110.65%.

Bidirectional motivated bimodal isothermal strand displacement amplifier with a table tennis-like movement for the ultrasensitive fluorescent and colorimetric detection of depression-related microRNA.

Abstract
An increasing number of studies have highlighted the potential of microRNAs (miRNAs) as physiological indicators of major depressive disorder (MDD). Herein, we developed a bidirectional-motivated bimodal isothermal strand displacement amplifier (BB-ISDA) for the ultrasensitive fluorescent and colorimetric detection of MDD-related miRNA-132. In the BB-ISDA system, a pair of functionalized hairpin probes (HP1 and HP2) with nicking recognition sites are designed to recognize target miRNA. The recognition of target miRNA by HP1 (or HP2) generates copious numbers of nicked triggers by HP1 (or HP2)-based ISDA to recognize HP2 (or HP1) by autonomous strand polymerization, cleavage, and displacement, which in turn induces the subsequent generation of copious numbers of nicked G-quadruplex triggers by HP2 (or HP1)-based ISDA to recognize HP1 (or HP2) along a same line. After many cycles, this bidirectional motivated table-tennis-like movement amplifies the fluorescent signal from HP1 and the colorimetric signal from HP2, simultaneously. The dual-signal output pattern was cross-validated for sensing miRNA-132. Each of the detection modal shows the capability for qualitative and quantitative detection of miRNA-132 with high sensitivity and specificity. The adaptability of the bimodal mechanism was verified via the detection of target miRNA-132 from clinical human blood samples. We envision that this BB-ISDA with dual-signal output for accurate and reliable analysis of miRNA is promising for the molecular diagnosis of human mental diseases.

Abstract
Spectrometers are essential analytical devices for analyzing fluid samples in biological, environmental, and disease diagnostic applications. However, the relatively high cost, the lack of portability, and the requirement for a constant power supply of bulky laboratory instruments limit their on-site applications. Herein, a wireless, cost-effective, open-source, and handheld spectrometer was designed and fabricated to realize the colorimetric and fluorescence analyses. It was built from off-the-shelf electronics utilizing 3D printing technology. The assembled device costs as little as $50. It has an overall dimension of 5 × 5 × 8 cm and an overall weight of only 130 g, which can easily fit in the palm of an adult's hand. It can detect light waves in the 405-690 nm range and transmit the read data to the corresponding SpecAnalysis Android application via Bluetooth. The feasibility of the device was demonstrated by the optical detection of Cu(II), bovine serum albumin, and calf thymus DNA. The sensitivity and detection limits of this device were comparable to those of commercial research-grade spectrophotometers and fluorescence spectrometers. The results suggest that the handheld spectrometer can be applied to detect a variety of substances, not limited to quantitative analysis of a specific individual compound.

Aptasensor-based assay for dual-readout determination of aflatoxin B1 in corn and wheat via an electrostatic force-mediated FRET strategy. Mikrochim Acta 2023; 190:80.

Abstract
A rapid and sensitive aptasensor was established for the dual-readout determination of aflatoxin B1 (AFB1) utilizing an electrostatically mediated fluorescence resonance energy transfer (FRET) signal amplification strategy. In the presence of AFB1, the aptamer preferentially bound to AFB1, resulting in the aggregation of bare gold nanoparticles (AuNPs) induced by NaCl, accompanied by a change of AuNP solution from wine-red to purple. This color change was used for colorimetric channel analysis. Then, the positively charged quantum dots were introduced into reaction system and interacted with negatively charged AuNPs, which successfully converted the color signal into a more sensitive fluorescence signal through FRET. The fluorescence quenching efficiency decreased with increasing concentrations of AFB1, and the fluorescence of aptasensor gradually recovered. The variation of fluorescence intensity was employed for fluorometric channel analysis. Under the optimal conditions, the color and fluorescence signals exhibited excellent response to AFB1 concentration within the ranges 10-320 ng·mL-1 and 3-320 ng·mL-1, respectively, and the limit of detection was as low as 7.32 ng·mL-1 and 1.48 ng·mL-1, respectively. The proposed aptasensor exhibited favorable selectivity, good recovery (85.3-113.4% in spiked corn and wheat samples), stable reproducibility (RSD<13.3%), and satisfactory correlation with commercial kits (R2=0.998). The aptasensor developed integrates advantages of modification-free, dual-readout, self-calibration, easy operation, and cost-effectiveness, while providing a simple and universal strategy for rapid and sensitive detection of mycotoxins in foodstuffs.

Abstract
Design of oligonucleotide probe-based isothermal amplification with the ability to identify miRNA biomarkers is crucial for molecular diagnostics. Herein, we engineered a miRNA-21 responsive G-quadruplex-deficient precursor hairpin probe (PHP) to achieve dual-mode detection of fluorescent signal and colorimetric signal. Due to lack of complete G-quadruplex sequence, PHP becomes shorter in length, lower background signal and less interference. Based on the polymerase-driven amplification mechanism, in the presence of miRNAs, two simultaneous amplification reaction processes will occur in PHP: miRNA-based amplification process and endogenous amplification process along the 3' end. Due to the positional difference between the starting points of the two amplification processes, the orderly and efficient occurrence of the two amplification processes can be achieved. Based on an interesting concept, PHP can achieve high detection performance with only simple amplification cycles. In such a way, the detection limits for fluorescence and colorimetry were 2.93 fM and 8.81 fM, which would cover most of clinical qualitative and quantitative needs. Thus, the accurate quantitative and visual miRNA detection technology based on PHP is beneficial to carry out extensive disease screening and treatment monitoring in various complex occasions.

Abstract
To address the urgent demand for sensitive and stable detection applications, significant efforts have been made in the development of dual-signal readout assays for precise target detection and timely health risk control. Here, a new nanomaterial, Pt@PCN-224-HRP-initiator DNA (PP-HRP-iDNA), was exploited to construct a dual-signal readout biosensing platform. Zr-MOF (PCN-224) was loaded with as many Pt nanoparticles (NPs) and as much horseradish peroxidase (HRP) as possible to enhance the brightness of the colorimetric signal recognizable to the naked eye while also acting as a gatekeeper to protect the enzyme activity and ensuring the stability of the assay process. Moreover, the Pt NPs and HRP displayed a synergistic catalytic effect, which promoted the sensitivity of detection. Further, the formation of the Zr-O-P bond eliminated the instability of the interactions between PCN-224 and iDNA in a controllable manner. After the immunoreaction, iDNA stimulated a hybridization chain reaction, resulting in a significant reduction of the fluorescent DNA in the supernatant and a fluorescent signal change. Subsequently, the PP-HRP-iDNA probe implemented UV-light response (450 nm) where 3,3',5,5'-tetramethylbenzidine was used as a substrate for the colorimetric signal readout. By virtue of the nanomaterial-modulated transduction mechanism and the antigen-antibody interactions, this dual-signal biosensor displays high sensitivity, with a limit of detection of 0.65 pg/mL for aflatoxin B1 and 4 CFU/mL for Salmonella enteritidis, suggesting the detection potential of the biosensing platform for analyzing various targets.
