Multiplexed and amplified chemiluminescence resonance energy transfer (CRET) detection of genes and microRNAs using dye-loaded hemin/G-quadruplex-modified UiO-66 metal-organic framework nanoparticles. Chem Sci 2021; 12:4810-4818. [PMID: 34163734 PMCID: PMC8179566 DOI: 10.1039/d0sc06744j] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Accepted: 02/07/2021] [Indexed: 01/11/2023] Open
Abstract
Dye-loaded UiO-66 metal-organic framework nanoparticles (NMOFs) modified with catalytic hemin/G-quadruplex DNAzyme labels act as functional hybrid modules for the chemiluminescence resonance energy transfer (CRET) analysis of miRNAs (miRNA-155 or miRNA-21) or genes (p53 or BRCA1). The dye-loaded NMOFs (dye = fluorescein (Fl) or rhodamine 6G (Rh 6G)) are modified with hairpin probes that are engineered to include in their loop domains recognition sequences for the miRNAs or genes, and in their stem regions caged G-quadruplex domains. In the presence of the analytes miRNAs or genes, the hairpin structures are opened, leading, in the presence of hemin, to the self-assembly of hemin/G-quadruplex DNAzyme labels linked to the dye-loaded NMOFs. In the presence of luminol and H2O2, the hemin/G-quadruplex DNAzyme labels catalyze the generation of chemiluminescence that provides radiative energy to stimulate the process of CRET to the dye loaded in the NMOFs, resulting in the luminescence of the loaded dye without external excitation. The resulting CRET signals relate to the concentrations of the miRNAs or the genes and allow the sensitive analysis of miRNAs and genes. In addition, the DNA hairpin-functionalized dye-loaded NMOF sensing modules were further applied to develop amplified miRNA or gene CRET-based sensing platforms. The dye-loaded NMOFs were modified with hairpin probes that include in their loop domain the recognition sequences for miRNA-155 or miRNA-21 or the recognition sequences for the p53 or BRCA1 genes. Subjecting the hairpin-modified NMOFs to the respective miRNAs or genes, in the presence of two hairpins H i and H j that include in their stem regions caged G-quadruplex subunit domains, results in the analyte-triggered opening of the probe hairpin linked to the NMOFs, and the opened hairpin tethers induce the cross-opening of the hairpins H i and H j by the hybridization chain reaction, HCR, resulting in the assembly of G-quadruplex wires tethered to the NMOFs. The binding of hemin to the HCR-generated chains yields hemin/G-quadruplex DNAzyme wires that enhance, in the presence of luminol/H2O2, the CRET processes in the hybrid nanostructures. These amplification platforms lead to the amplified sensing of miRNAs and genes. By mixing the Fl- and Rh 6G-loaded hairpin-functionalized UiO NMOFs, the multiplexed CRET detection of miRNA-155, miRNA-21 and the p53 and BRCA1 genes is demonstrated.

Abstract
Semiconductor nanoparticles particularly quantum dots (QDs) are interesting alternatives to organic fluorophores for a range of applications such as biosensing, imaging and therapeutics. Addition of a programmable scaffold such as DNA to QDs further expands the scope and applicability of these hybrid nanomaterials in biology. In this review, the most important stages of preparation of QD-DNA conjugates for specific applications in biology are discussed. Special emphasis is laid on (i) the most successful strategies to disperse QDs in aqueous media, (ii) the range of different conjugation with detailed discussion about specific merits and demerits in each case, and (iii) typical applications of these conjugates in the context of biology.

Abstract
Acute myocardial infarction (AMI) is one of the leading causes of death throughout the world. Usual methods for detecting AMI are expensive, time-consuming and using blood samples as biological samples. Therefore, creating an ultra-fast, sensitive and non-invasive diagnostic test is necessary. Herein, a novel ultra-sensitive, fluorescent, plasmon-exciton coupling hybrid of a gold nanoparticle-quantum dot (PQ)-based aptamer nanobiosensor is presented for the detection of human cardiac troponin I (cTnI), the golden biomarker of AMI, and a preclinical test is performed within saliva. The binding of the cTnI protein to aptamer leads to a fluorescence enhancement of the plexcitonic hybrid system. The response range of this nanobiosensor is 0.4-2500 fM and the limit of detection is 0.3 fM. It seems that this novel design of nanobiosensor in the form of the PQ plexcitonic hybrid system can presents new opportunities for nanobiosensor progress.

Two-wheel drive-based DNA nanomachine and its sensing potential for highly sensitive analysis of cancer-related gene. Biomaterials 2016; 100:110-7.

Abstract
With the biological significance and important advances of nano-scale DNA devices, scientific activities have been directed toward developing molecular machinery. In this work, we present a novel two-wheel drive-based DNA nanomachine composed of one signaling recognition probe (SRP), one label-free recognition probe (LRP), and one driving primer (DP). Target DNA hybridization can activate LRP-based wheel driving by resorting to DP-mediated polymerization/nicking/displacement cycles. This in turn results in the accumulation of nicked strand 1 (NS1) that can initiate extended SRP-based wheel driving. As a result, the hairpin structure of SRP is stretched and pre-quenched fluorescence is restored. Meanwhile, lots of nicked strand 2 (NS2) are produced, which could hybridize perfectly with SRP and lead to further fluorescence amplification. It is worth noting that, because the nanomachine operation relies strongly on inputted target trigger, the unwanted background is completely eliminated. The detection limit of 1 pM and an excellent capability to recognize the single-base mutation were achieved. Significantly, the interrogating of target trigger extracted from cancer cells is already available, reflecting the potential for practical applications. As a proof-of-concept building, the unique analytical properties would significantly benefit the DNA nanomachines and reveal great promise in biochemical and biomedical studies.

Abstract
Semiconductor quantum dots (QDs) or nanoparticles (NPs) exhibit very unusual physico-chemcial and optical properties. This review article introduces the applications of semiconductor nanomaterials (NMs) in fluorescence spectroscopy and matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for biomolecule analysis. Due to their unique physico-chemical and optical properties, semiconductors NMs have created many new platforms for investigating biomolecular structures and information in modern biology. These semiconductor NMs served as effective fluorescent probes for sensing proteins and cells and acted as affinity or concentrating probes for enriching peptides, proteins and bacteria proteins prior to MALDI-MS analysis.

Abstract
We synthesized and characterized small yet highly robust silica-coated quantum dots (QDs) and then used them to develop highly sensitive molecular beacon (MB) for DNA detection. As compared to the previously reported methods, our silica coating approach enabled simple and rapid synthesis of silica-coated QDs in large quantities and high concentrations with a well-controlled silica layer. The QDs such made were stable and had a high quantum yield in a wide range of pH values (1-14) and high salt concentrations (up to 2 M). They were less than 10 nm in diameter, much smaller than current silica-coated QDs, thus allowing for efficient energy transfer. The MB sensor based on these silica-coated QDs was capable of rapidly detecting the target DNA at 0.1 nM concentration within 15 min. It could also differentiate the target DNA from the single base mismatched DNA. The QD-MB developed in this work can be used for highly sensitive and selective detection of DNA and other biomolecules in homogeneous solution and inside a cell, as well as in harsh environment.

Abstract
We developed highly sensitive and specific nanosensors based on quantum dots (QDs) and DNAzyme for multiplexed detection of heavy metal ions in liquid. The QDs were coated with a thin silica layer for increased stability and higher quantum yield while maintaining a relatively small size for highly efficient energy transfer. The QD-DNAzyme nanosensors were constructed by conjugating quencher-labeled DNAzymes onto the surface of carboxyl-silanized QDs. In the presence of metal ions, the emission is restored due to the cleavage of DNAzymes. The detection could be completed within 25 min with a single laser excitation source. The detection limit of 0.2 and 0.5 nM was experimentally achieved for Pb(2+) and Cu(2+), respectively, which is a 50- and 70-fold improvement over the recent results obtained with dye molecules. Multiplexed detection was also demonstrated using two different colors of QDs, showing negligible cross-talk between the Pb(2+) detection and Cu(2+) detection.

Abstract
Detection of DNA sequences has received broad attention due to its potential applications in a variety of fields. As sensitivity of DNA biosensors is determined by signal variation of hybridization events, the signal enhancement is of great significance for improving the sensitivity in DNA detection, which still remains a great challenge. Nanomaterials, which possess some unique chemical and physical properties caused by nanoscale effects, provide a new opportunity for developing novel nanomaterial-based signal-enhancers for DNA biosensors. In this review, recent progress concerning this field, including some newly-developed signal enhancement approaches using quantum-dots, carbon nanotubes and their composites reported by our group and other researchers are comprehensively summarized. Reports on signal enhancement of DNA biosensors by non-nanomaterials, such as enzymes and polymer reagents, are also reviewed for comparison. Furthermore, the prospects for developing DNA biosensors using nanomaterials as signal-enhancers in future are also indicated.
