Abstract
Electrochemical biosensors include a recognition component and an electronic transducer, which detect the body fluids with a high degree of accuracy. More importantly, they generate timely readings of the related physiological parameters, and they are suitable for integration into portable, wearable and implantable devices that are significant relative to point-of-care diagnostics scenarios. As an example, the personal glucose meter fundamentally improves the management of diabetes in the comfort of the patients' homes. This review paper analyzes the principles of electrochemical biosensing and the structural features of electrochemical biosensors relative to the implementation of health monitoring and disease diagnostics strategies. The analysis particularly considers the integration of the biosensors into wearable, portable, and implantable systems. The fundamental aim of this paper is to present and critically evaluate the identified significant developments in the scope of electrochemical biosensing for preventive and customized point-of-care diagnostic devices. The paper also approaches the most important engineering challenges that should be addressed in order to improve the sensing accuracy, and enable multiplexing and one-step processes, which mediate the integration of electrochemical biosensing devices into digital healthcare scenarios.

Abstract
The robust point-of-care platform for sensitive, multiplexed, and affordable detection of allergen-specific IgE (sIgE) is an urgent demand in component-resolved diagnostics. Here, we developed a microfluidic immunosensing platform based on a rolling circle amplification-assisted DNA dendrimer probe for sensitive detection of multiple sIgEs. The versatile multichannel microfluidic whole blood analytical device integrates cell filtration, recombinant antigen-modified magnetic enrichment, and DNA dendrimer probe-amplified signal transduction for portable on-chip analysis. Three sIgEs against common oyster allergens were simultaneously detected in blood samples by simple smartphone-based imaging without any pretreatment. The quantitative detection of multiple allergen-specific antibodies on the platform was achieved with limits of detection of less than 50 pg/mL, exhibiting superior sensitivity compared to most point-of-care testing. The detection results of 55 serum samples and 4 whole blood samples were 100% consistent with the ELISA results, confirming the accuracy and stability of our platform. Additionally, the reversible combination of hexahistidine6-tag and Ni-IMAC magbead was elegantly utilized on the immunosensing platform for desired reversibility. With the advantages of general applicability, high sensitivity, and reversibility, the DNA dendrimer-based microfluidic immunosensing platform provides great potential for the portable detection of immune proteins as a point-of-care platform in disease diagnostics and biological analysis.

Abstract
A novel immunochromatography strip (ICS) based on the DNA-bridged double gold nanoparticles was established and evaluated for the dual-mode detection of ochratoxin A (OTA). For this purpose, the streptavidin was coupled with the big size of gold nanoparticle (40 nm, AuNP), the OTA monoclonal antibody and biotinylated DNA-SH were simultaneously immobilized on the small size of AuNP (20 nm), and then the enhanced ICS was self-assembled and evaluated. The dual-mode detection of semi-quantification and quantification had been achieved and performed by the proposed ICS. The LOD for semi-quantification (semi-Q-LOD) was 0.06 ng/mL by the directly naked eye (eightfold enhanced than conventional ICS). By the on-site reader, the LOD for quantification (Q-LOD) was 0.03 ng/mL (threefold enhanced), with the detection range between 0.03 and 1.2 ng/mL. The specificity, reliability, and practicability had been well represented. Furthermore, the OTA-positive results of the enhanced ICS method correlated well with those obtained by the referenced HPLC-MS/MS for the market samples. This study provided a new ICS pattern of semi-quantification and quantification for OTA contamination, which could be used as a valuable reference for improving the ICS technology and enhancing the sensitivity.

Abstract
This study showed a method of synthetization of a methylene blue-functionalized DNA concatemer via hybridization chain reaction (HCR) used for turn-off fluorescence detection of carcinoembryonic antigen (CEA). During the experiments, CEA aptamers and the methylene blue-functionalized DNA concatemer were modified onto the surface of Au nanoparticles (AuNPs). By detecting the signal of remaining methylene blue in the solution that has not been embedded in the DNA concatemer, we obtained an amplified decrease of the fluorescence signal at 695 nm for CEA. The linear range was from 0.1 to 80 ng mL-1 with a limit of detection at 75 pg mL-1 for CEA determination. Our results showed that the proposed method had good selectivity and could generate satisfactory results for clinical serum sample determination. Based on the positive outcomes obtained, we determined that the method provided a sensitive and accurate way for early clinical diagnosis of cancer disease.

Abstract
Proximity ligation assay (PLA) is a vigorously developed homogeneous immunoassay assisted by DNA combining dual recognition of target protein by pairs of proximity probes, in which the detection of protein is tactfully converted to the detection of DNA. The booming developments in PLA have enabled a variety of ultrasensitive assays for the detection of protein and this concept of PLA is also extended to the detection of nucleic acids and some small molecule. The association between PLA and electrochemical method, defined as electrochemical proximity ligation assay (ECPLA), has gained much interests in disease diagnosis, food safety and environmental assays with the advantages, such as broad range of targets, simplicity, low cost and rapid response. In this review, we took a different perspective to present the history of PLA, the classical ECPLA biosensing methodology as well as the developments of ECPLA based on several key parameters, such as sensitivity, selectivity, reusability and generalization. In addition, the developments of PLA with electrochemiluminescence as readout are also presented. Finally, perspective and some unresolved challenges in ECPLA that can potentially be addressed have also been discussed.

Abstract
As significant components of the organism, carbohydrates and glycoconjugates play indispensable roles in energy supply, cell signaling, immune modulation, and tumor cell invasion, and function as biomarkers since aberrance of them has been proved to be associated with the emergence and development of certain diseases. Functional nucleic acids (FNAs) have properties including easy-to-synthesize, good stability, good biocompatibility, low cost, and high programmability, they have attracted significant research attention and been incorporated into biosensors for detecting disease-related carbohydrates and glycoconjugates. This review summarizes the construction strategies and biosensing applications of FNAs-based biosensors in glycobiology in terms of target recognition and signal transduction. By illustrating the mechanisms and comparing the performances, the challenges and development opportunities in this area have been critically elaborated. We believe that this review will provide a better understanding of the role of FNAs in the analysis of disease-related carbohydrates and glycoconjugates, and inspire further discovery in fields that include glycobiology, chemical biology, clinical diagnosis, and drug development.

Abstract
The isothermal exponential amplification technology have rarely been fabricated as the universal sensing platform for the detection of various proteins. To broaden its application, we here developed a strategy named protein recognition-initiated exponential amplification reaction (PRIEAR) using protein recognition to induce the DNA assembly which converts protein recognition events into ssDNA amplicons and combining two-stage amplification to achieve exponential amplification technology. Taking advantage of this principle, diverse biomarkers can be quantified at sub-picomolar concentrations in the homogenous manner, making the PRIEAR suitable for clinical practice. Therefore, this strategy can expand the powerful isothermal exponential amplification technology to protein targets and thus provide a new toolbox into the clinical and biomedical applications.

Abstract
RNA-cleaving DNAzymes and their multicomponent nucleic acid enzymes (MNAzymes) have been successfully used to detect nucleic acids and proteins. The appropriate split of the catalytic cores of DNAzymes is critical to the formation of MNAzymes with high catalytic activities. However, for protein detection, no systematic investigation has been made on the effects of the split locations and secondary structures of MNAzymes on the catalytic activities of the cleavage reaction. We systematically studied how split locations and secondary structures affect the activity of the MNAzymes that catalyze multiple cleavage steps. We engineered the MNAzymes on the basis of the RNA-cleaving DNAzyme 10-23 as a model system. We designed 28 pairs of MNAzymes, representing 14 different split locations and two secondary structures: the three-arm and the four-arm structures. By comparing the multiple turnover numbers (kobs.m) of the 28 MNAzymes, we showed that the split location between the seventh cytosine and the eighth thymine of the catalytic core region and the four-arm structure resulted in optimum catalytic activity. Binding-induced DNA assembly of the optimized MNAzymes enabled sensitive detection of two model protein targets, demonstrating promising potential of the binding-assembled MNAzymes for protein analysis. The strategy of binding-assembled MNAzymes and systematic studies measuring multiple turnover numbers (kobs.m) provide a new approach to studying other partial (split) DNAzymes and engineering better MNAzymes for the detection of specific proteins.

Abstract
Sensitive detection of the SARS-CoV-2 protein remains a great research interest in clinical screening and diagnosis owing to the coronavirus epidemic. Here, an ultrasensitive chemiluminescence (CL) imaging strategy was developed through proximity hybridization to trigger the formation of a rolling circle-amplified G-quadruplex/hemin DNAzyme for the detection of the SARS-CoV-2 protein. The target protein was first recognized by a pair of DNA-antibody conjugates, Ab-1 and Ab-2, to form a proximity-ligated complex, Ab-1/SARS-CoV-2/Ab-2, which contained a DNA sequence complemental to block DNA and thus induced a strand displacement reaction to release the primer from a block/primer complex. The released primer then triggered a rolling circle amplification to form abundant DNAzyme units in the presence of hemin, which produced a strong chemiluminescent signal for the detection of the target protein by catalyzing the oxidation of luminol by hydrogen peroxide. The proposed assay showed a detectable concentration range over 5 orders of magnitude with the detection limit down to 6.46 fg/mL. The excellent selectivity, simple procedure, acceptable accuracy, and intrinsic high throughput of the imaging technique for analysis of serum samples demonstrated the potential applicability of the proposed detection method in clinical screening and diagnosis.

Abstract
When dealing with infectious pathogens, the risk of contamination or infection in the process of detecting them is nonnegligible. Separation-free detection will be beneficial in operation and safety. In this work, we proposed a DNAzyme walker for homogeneous and isothermal detection of enterovirus. The DNAzyme is divided into two inactivate subunits. When the subunit-conjugated antibody binds to the target virus, the activity of the DNAzyme recovers as a result of spatial proximity. The walker propels, and the fluorescence recovers. The final fluorescence intensity of the reaction mixture is related to the concentration of the target virus. The detection limit of this proposed method is 6.6 × 104 copies/mL for EV71 and 4.3 × 104 copies/mL for CVB3, respectively. Besides, this method was applied in detection of EV71 in clinical samples with a satisfactory result. The entire experiment is easy to operate, and the proposed method has great potential for practical use.

Abstract
Facile detection of tumour-derived extracellular vesicles (EVs) is crucial to cancer diagnosis. Herein, a facile and label-free electrochemical aptasensor was fabricated to detect tumour-derived EVs based on the target-induced proximity hybridization of split aptamers. In this assay, two designed oligonucleotide probes containing fragments of a protein tyrosine kinase-7 (PTK7) aptamer were used to recognize and capture EVs containing PTK7. In the presence of target EVs, the aptamer-target ternary complex could induce proximity hybridization and form a DNA duplex on the electrode. The DNA duplex could bind more electroactive Ru(NH3)63+ through electrostatic attraction, resulting in an increased cathodic current signal. By virtue of the excellent electrochemical signal reporter RuHex, the specificity of the aptamer and proximity ligation, a facile EV electrochemical aptasensor with a detection limit of 6.607 × 105 particles per mL was realized. Furthermore, this aptasensor showed good selectivity to distinguish different tumour-derived EVs and was applied to detect EVs in complex biological samples. The proposed electrochemical aptasensor can be further extended to the detection of other EVs, thus showing great potential in clinical diagnosis.

Abstract
Nucleic acid enzymes (NAzymes) are nucleic acid molecules with catalytic activity. A subset, the RNA-cleaving NAzyme, is characterized by its substrate of choice: an RNA unit. These enzymes have been used for diverse applications, including biosensor development, akin to their protein counterparts. Owing to their function as both biorecognition elements and signal generators, robust bioassays based entirely on NAzyme molecules have been developed. Additionally, unique mechanisms for integration with other biorecognition elements and signal generation methods have been explored to realize ultrasensitive, specific, and user-friendly biosensors. Furthermore, NAzyme-based bioassays have already broken into the in vitro diagnostics market, with more promise in the pipeline.

Abstract
In this work, a novel two-dimensional (2D) ultrathin metal-organic layer (MOL) based on the aggregation-induced emission (AIE) ligand H4ETTC (H4ETTC = 4',4''',4''''',4'''''''-(ethene-1,1,2,2-tetrayl)tetrakis(([1,1'-biphenyl]-4-carboxylic acid))) was developed and used to construct a novel electrochemiluminescence (ECL) aptasensor for ultrasensitive detection of carcinoembryonic antigen (CEA). The newly synthesized AIE luminogen (AIEgen)-based MOL (Hf-ETTC-MOL) yielded a higher ECL intensity and efficiency than did H4ETTC monomers, H4ETTC aggregates and 3D bulk Hf-ETTC-MOF. This improvement occurred not only because the ETTC ligands were coordinatively immobilized in a rigid MOL matrix, which restricted the intramolecular free rotation and vibration of these ligands and then reduced the non-radiative transition, but also because the porous ultrathin 2D MOL greatly shortened the transport distances of ions, electrons, coreactant (triethylamine, TEA) and coreactant intermediates (TEA˙ and TEA˙+), which made more ETTC luminophores able to be excited and yielded a high ECL efficiency. On the basis of using the Hf-ETTC-MOL as a novel ECL emitter and rolling circle amplification (RCA) as a signal amplification strategy, the constructed ECL aptasensor exhibited a linear range from 1 fg mL-1 to 1 ng mL-1 with a detection limit of 0.63 fg mL-1. This work has opened up new prospects for developing novel ECL materials and is expected to lead to increased interest in using AIEgen-based MOLs for ECL sensing.

Abstract
A widely applicably method is described for fluorometric determination of targets such as microRNA and viral DNA. It is making use of a Mg(II)-dependent DNAzyme and a G-quadruplex. In the absence of analyte, an inactive DNAzyme is formed by the hybridization of split DNAzymes and substrate. On addition of target analyte, the end of each strand of the split DNAzymes bind the analyte. This leads to the generation of an active DNAzyme. In the presence of Mg(II), the activated DNAzyme is formed and can cleave the substrate strand. Hence, the caged G-quadruplex sequences will be released. These released G-quadruplexes combine with thioflavin T to generate a G-quadruplex/thioflavin T complex and thereby cause amplified fluorescence. The method shows a 70 pM detection limit for H5N1 and works over a wide linear range 1 nM to 400 nM. Conceivably, this detection scheme has a wide scope in that it may be applied to other assays for microRNAs and DNAs by variation of the type of DNAzyme. Graphical abstract Schematic presentation of target detection: the DNAzyme cannot cleave the substrate strand when target is absent. Once the target is added, the active DNAzyme can cleave the substrate strand in the presence of Mg2+, resulting in significant fluorescence enhancement when the release of the caged G-quadruplex sequences binding with 2-[4-(dimethylamino)phenyl]-3,6-dimethylbenzothiazolium chloride (ThT).

Abstract
We present an electrochemical DNA detection strategy based on self-assembled ferrocene-cored poly(amidoamine) dendrimers for the detection of a gene relevant to breast cancer. The chemisorption of three ferrocene-cored poly(amidoamine) generations and hybridization of single-stranded DNA on a Au electrode were studied by cyclic voltammetry and differential pulse voltammetry. The biosensor demonstrated high sensitivity of 0.13 μA/(ng/ml) in the detection of the target DNA with a linear range of 1.3-20 nM and a detection limit of 0.38 nM. The DNA biosensor also has high selectivity for the target DNA, showing a clear signal difference from a noncomplementary sequence and a single-base-mismatch sequence, which was used as a model of BRAC1 gene mutation. The results shown are highly motivating for exploring DNA biosensing technology in the diagnosis of breast cancer caused by mutation of the BRAC1 gene. Graphical abstract.

Abstract
In this work, we have developed a novel fluorescent aptasensor based on single oligonucleotide-mediated isothermal quadratic amplification (SOIQA) and graphene oxide (GO)-mediated fluorescence quenching for the ultrasensitive detection of proteins in a homogeneous solution. The SOIQA consists of a fluorophore-labeled aptamer hairpin probe containing T7 exonuclease (T7 Exo)-resistant 5'-protruding termini and a mismatch base at its 3'-end, DNA polymerase, T7 Exo and GO. The target analyte binds with the aptamer sequences and unfolds the fluorophore-labeled aptamer hairpin probe to form a new DNA hairpin, inducing the catalytic recycling of the target analyte (assisted by DNA polymerase) and DNA sequences (aided by T7 Exo) to achieve SOIQA, which results in the digestion of numerous fluorophore-labeled aptamer hairpin probes and the generation of a large amount of mononucleotides carrying the fluorophore. These mononucleotide products cannot be adsorbed onto the GO, leading to a dramatic increase in the fluorescence intensity for the amplified detection of the target molecules. In the absence of the target analyte, however, the SOIQA reaction is inhibited and the fluorophore-labeled aptamer hairpin probe is adsorbed onto the GO, leading to an extremely low fluorescence background signal. To test the feasibility of the SOIQA systems, a protein cancer marker, carcinoembryonic antigen (CEA) was used as the model analyte. The developed aptasensor could detect CEA with a detection limit of 28.5 fg mL-1 (∼142 aM), high specificity and a broad detection range of 6 orders of magnitude. And this one-step incubation can be completed in 60 min. In addition, the approach uses only one oligonucleotide strand, and is simple. Moreover, this SOIQA sensing method is suitable for rapid and direct quantification of proteins in complex biological samples such as clinical serum. Considering the simplicity and superior sensitivity/specificity, the developed sensing method provides a promising platform for the analysis of a variety of low-abundance biomolecules.

Re-engineering 10-23 core DNA- and MNAzymes for applications at standard room temperature. Anal Bioanal Chem 2018; 411:205-215.

Abstract
DNA- and MNAzymes are nucleic acid-based enzymes (NAzymes), which infiltrated the otherwise protein-rich field of enzymology three decades ago. The 10-23 core NAzymes are one of the most widely used and well-characterized NAzymes, but often require elevated working temperatures or additional complex modifications for implementation at standard room temperatures. Here, we present a generally applicable method, based on thermodynamic principles governing hybridization, to re-engineer the existing 10-23 core NAzymes for use at 23 °C. To establish this, we first assessed the activity of conventional NAzymes in the presence of cleavable and non-cleavable substrate at 23 °C as well as over a temperature gradient. These tests pointed towards a non-catalytic mechanism of signal generation at 23 °C, suggesting that conventional NAzymes are not suited for use at this temperature. Following this, several novel NAzyme-substrate complexes were re-engineered from the conventional ones and screened for their performance at 23 °C. The complex with substrate and substrate-binding arms of the NAzymes shortened by four nucleotides on each terminus demonstrated efficient catalytic activity at 23 °C. This has been further validated over a dilution of enzymes or enzyme components, revealing their superior performance at 23 °C compared to the conventional 10-23 core NAzymes at their standard operating temperature of 55 °C. Finally, the proposed approach was applied to successfully re-engineer three other new MNAzymes for activity at 23 °C. As such, these re-engineered NAzymes present a remarkable addition to the field by further widening the diverse repertoire of NAzyme applications.

Abstract
Sensitive and specific detection of HIV-related DNA is of great importance for early accurate diagnosis and therapy of HIV-infected patients. Here, we developed a one-step and rapid fluorescence strategy for HIV-related DNA detection based on strand displacement amplification and a Mg2+-dependent DNAzyme reaction. In the presence of target HIV DNA, it can hybridize with template DNA and activate strand displacement amplification to generate numerous DNAzyme sequences. With the introduction of Mg2+, DNAzyme can be activated to circularly cleave the substrate DNA, which leads to the separation of fluorophore reporters from the quenchers, resulting in the recovery of the fluorescence. Under the optimal experimental conditions, the established biosensing method can detect target DNA down to 61 fM with a linear range from 100 fM to 1 nM, and discriminate target DNA from mismatched DNA perfectly. In addition, the developed biosensing strategy was successfully applied to assay target DNA spiked into human serum samples. With the advantages of fast, easy operation and high-performance, this biosensing strategy might be an alternative tool for clinical diagnosis of HIV infection.

Abstract
The problems of environmental security and the potential risks of human health caused by transgenic crops have attracted much attention. Recent studies reveal 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) from Agrobacterium sp. strain CP4 protein (CP4-EPSPS), which shows very high resistance to herbicide glyphosate, is a typical biomarker of genetically modified (GM) crops. For this reason, it is highly anticipated to devise a sensitive and convenient strategy to detect CP4-EPSPS protein in crops. Herein, we report a simple electrochemical immunosensor by coupling nanobody, ordered mesoporous carbon (OMC), and thionine (Th). As a capture agent, the nanobody was screened out from an immunized Bactrian camel, and exhibited superior properties with respect to conventional antibody, such as higher stability and stronger heat resistance. Moreover, OMC offered an effective platform with high surface area, electrical conductivity, and biocompatibility, which greatly facilitated the assembly of redox probe Th, and further coupling of large amount of capture nanobodies. As a result, the CP4-EPSPS protein could be determined with high sensitivity and efficiency by differential pulse voltammetry (DPV) in a wide linear range from 0.001 to 100 ng·mL-1 with a low detection limit of 0.72 pg·mL-1, which was more than 3 orders of magnitude lower than those of previously reported works. As an example, the proposed electrochemical immunosensor was successfully applied to spiked samples, demonstrating its great potential in CP4-EPSPS screening and detection.

Abstract
In this work, a new electrochemical immunosensor was developed for prion protein assay based on hybridization chain reaction (HCR) with hemin/G-quadruplex DNAzyme for signal amplification. In this amplification system, the hemin/G-quadruplex DNAzyme simultaneously mimicked the biocatalytic functions for H2O2 reduction and L-cysteine oxidation. In the presence of L-cysteine, the hemin/G-quadruplex catalyzed the oxidation of L-cysteine to L-cystine. At the same time, H2O2 was produced under the oxygen condition. Then, the hemin/G-quadruplex could quickly catalyze the reduction of H2O2, mimicking the catalytic performance of horseradish peroxidase (HRP). Under the optimal conditions, the immunosensor showed a wide linear response range from 0.5 pg/mL to 100 ng/mL with the low detection limit of 0.38 pg/mL (3σ). By changing the specific antibody, this strategy could be easily extended to detect the infectious isoform of prion (PrPSc) and other proteins. Based on its good analytical performance, the developed method shows great potential applications in diagnosis of prion diseases at presymptomatic stage and bioanalysis.

Abstract
A synthetic DNA machine performs quasi-mechanical movements in response to external intervention, suggesting the promise of constructing sensitive and specific biosensors. Herein, a smart DNA walker biosensor for label-free detection of carcinoembryonic antigen (CEA) is developed for the first time by a novel cascade amplification strategy of exonuclease (Exo) III-assisted target recycling amplification (ERA) and DNA walker. ERA as the first stage of amplification generates the walker DNA, while the autonomous traveling of the walker DNA on the substrate-modified silica microspheres as the second stage of amplification produces an ultrasensitive fluorescent signal with the help of N-methylmesoporphyrin IX (NMM). The DNA machine as a biosensor could be applied for transducing and quantifying signals from isothermal molecular amplifications, avoiding the complicated reporter elements and thermal cycling. The present biosensor achieves a detection limit of 1.2 pg·mL-1 within a linear range of 10 pg·mL-1 to 100 ng·mL-1 for CEA, along with a favorable specificity. The practical applicability of the biosensor is demonstrated by the detection of CEA in human serum with satisfactory results; thus, it shows great potential in clinical diagnosis.

Abstract
Development of an efficient sensing platform capable of continual monitoring of biomarkers is needed to assess the functionality of the in vitro organoids and to evaluate their biological responses toward pharmaceutical compounds or chemical species over extended periods of time. Here, a novel label-free microfluidic electrochemical (EC) biosensor with a unique built-in on-chip regeneration capability for continual measurement of cell-secreted soluble biomarkers from an organoid culture in a fully automated manner without attenuating the sensor sensitivity is reported. The microfluidic EC biosensors are integrated with a human liver-on-a-chip platform for continual monitoring of the metabolic activity of the organoids by measuring the levels of secreted biomarkers for up to 7 d, where the metabolic activity of the organoids is altered by a systemically applied drug. The variations in the biomarker levels are successfully measured by the microfluidic regenerative EC biosensors and agree well with cellular viability and enzyme-linked immunosorbent assay analyses, validating the accuracy of the unique sensing platform. It is believed that this versatile and robust microfluidic EC biosensor that is capable of automated and continual detection of soluble biomarkers will find widespread use for long-term monitoring of human organoids during drug toxicity studies or efficacy assessments of in vitro platforms.

Abstract
The detection of protein is vital to fundamental research as well as practical applications. However, most detection methods depend on antibody-based assays which are faced with many shortcomings. Herein, we propose a colorimetric method for protein assays based on target-triggered activation of aptazyme, which may offer simple, rapid and cost-effective detection of the target protein. In this method, the conformation change of aptazyme induced by target protein is designed to be associated with aptazyme activation. Consequently, in the presence of the target protein, the designed DNA linkers will be cleaved into two fragments that fail to cross-link gold nanoparticles (GNPs), thus the color of GNP solution remains red, while the color will be changed in the absence of the target. Because of the advantages of aptazyme such as economic synthesis, stable, easy modification and its ability to accomplish signal recognition and signal amplification simultaneously, the method is thermostable, simple and cost-efficient. In this work, we have taken the detection of vascular endothelial growth factor (VEGF) as an example, which can present an analytical performance with as low as 0.1 nM detection limit, spanning a detection range of 3 orders of magnitude. What is more, the principle of this proposed new method can be extended as a universal assay method not only for the detection of analytes which have an aptamer but also for those analytes that have ligands.

Abstract
Some natural enzymes increase the rate of diffusion-limited reactions by facilitating substrate flow to their active sites. Inspired by this natural phenomenon, we developed a strategy for efficient substrate delivery to a deoxyribozyme (DZ) catalytic sensor. This resulted in a three- to fourfold increase in sensitivity and up to a ninefold improvement in the detection limit. The reported strategy can be used to enhance catalytic efficiency of diffusion-limited enzymes and to improve sensitivity of enzyme-based biosensors.
