El Aamri M, Mohammadi H, Amine A. A highly sensitive colorimetric DNA sensor for MicroRNA-155 detection: leveraging the peroxidase-like activity of copper nanoparticles in a double amplification strategy. Mikrochim Acta 2023; 191:32. [PMID: 38102528 DOI: 10.1007/s00604-023-06087-1] [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: 09/22/2023] [Accepted: 11/06/2023] [Indexed: 12/17/2023]
Abstract
A novel and highly sensitive colorimetric DNA sensor for determination of miRNA-155 at attomolar levelsis presented that combines the peroxidase-like activity of copper nanoparticles (CuNPs) with the hybridization chain reaction (HCR) . The utilization of CuNPs offers advantages such as strong interaction with double-stranded DNA, excellent molecular recognition, and mimic catalytic activity. Herein, a capture probe DNA (P1) was immobilized on carboxylated magnetic beads (MBs), allowing for amplified immobilization due to the 3D surface. Subsequently, the presence of the target microRNA-155 led to the formation of a sandwich structure (P2/microRNA-155/P1/MBs) when P2 was introduced to the modified P1/MBs. The HCR reaction was then triggered by adding H1 and H2 to create a super sandwich (H1/H2)n. Following this, Cu2+ ions were attracted to the negatively charged phosphate groups of the (H1/H2)n and reduced by ascorbic acid, resulting in the formation of CuNPs, which were embedded into the grooves of the (H1/H2)n. The peroxidase-like activity of CuNPs catalyzed the oxidation reaction of 3,3',5,5'-Tetramethylbenzidine (TMB), resulting in a distinct blue color measured at 630 nm. Under optimal conditions, the colorimetric biosensor exhibited a linear response to microRNA-155 concentrations ranging from 80 to 500 aM, with a detection limit of 22 aM, and discriminate against other microRNAs. It was also successfully applied to the determination of microRNA-155 levels in spiked human serum.

DNA-based platform for efficient and precisely targeted bioorthogonal catalysis in living systems. Nat Commun 2022; 13:1459. [PMID: 35304487 PMCID: PMC8933418 DOI: 10.1038/s41467-022-29167-x] [Citation(s) in RCA: 38] [Impact Index Per Article: 19.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Accepted: 02/17/2022] [Indexed: 12/30/2022] Open
Abstract
As one of the typical bioorthogonal reactions, copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction holds great potential in organic synthesis, bioconjugation, and surface functionalization. However, the toxicity of Cu(I), inefficient catalytic activity, and the lack of cell specific targeting of the existing catalysts hampered their practical applications in living systems. Herein, we design and construct a DNA-based platform as a biocompatible, highly efficient, and precisely targeted bioorthogonal nanocatalyst. The nanocatalyst presents excellent catalytic efficiency in vitro, which is one order of magnitude higher than the commonly used catalyst CuSO4/sodium ascorbate. The theoretical calculation further supports the contribution of DNA structure and its interaction with substrates to the superior catalytic activity. More importantly, the system can achieve efficient prodrug activation in cancer cells through cell type-specific recognition and produce a 40-fold enhancement of transformation compared to the non-targeting nanocatalyst, resulting in enhanced antitumor efficacy and reduced adverse effects. In vivo tumor therapy demonstrates the safety and efficacy of the system in mammals. Copper-click reaction has been used for a wide range of bio-conjugations but does suffer from toxicity issues. Here, the authors report on the growth of copper nanoparticles on DNA with linked aptamer targeting and demonstrate high catalytic effect and improved application due to targeting and biocompatibility.

A label-free cyclic amplification strategy for microRNA detection by coupling graphene oxide-controlled adsorption with superlong poly(thymine)-hosted fluorescent copper nanoparticles. Talanta 2022; 243:123323. [PMID: 35247818 DOI: 10.1016/j.talanta.2022.123323] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 02/11/2022] [Accepted: 02/14/2022] [Indexed: 12/22/2022]
Abstract
Herein, based on a terminal deoxynucleotidyl transferase (TdT)-mediated superlong poly-T-templated-copper nanoparticles (poly T-CuNPs) strategy, a simple, universal and label-free fluorescent biosensor for the detection of miRNA was constructed by employing graphene oxide (GO) and DNase I. In this strategy, GO and DNase I were used as a switch and amplifier of the signal generation pathway, respectively, and the fluorescence of poly T-CuNPs was used as the signal output. In the presence of target miRNA, the DNA dissociated from the GO surface by forming a miRNA/DNA duplex and was degraded by DNase I. The short oligos with 3'-OH, the product of DNase I degradation, could be recognized by the TdT and added to a long poly-T tail. Finally, the fluorescence signal was output through the synthesis of poly T-CuNPs. As a proof of concept, let-7a was analyzed. The method showed good sensitivity and selectivity with a linear response in the 50 pM-10,000 pM let-7a concentration range and a 30 pM limit of detection (LOD = 30 pM, R2 = 0.9954, the relative standard deviation were 2.79%-5.30%). It was also successfully applied to the determination of miRNA in spiked human serum samples. It showed good linearity in the range of 500-10000 pM (R2 = 0.9969, the relative standard deviation were 1.61%-3.85%). Moreover, both the adsorption of GO and the degradation of DNase I are DNA sequence-independent; thus, this method can be applied to the detection of any miRNA simply by changing the assisted-DNA sequence.

Abstract
The development and application of metal nanoclusters (MNCs) in nucleic acid testing in the past 10 years have been summarized. Fluorescence enhancement and red shift can occur when the G-rich sequence gets close to Ag NCs or the complementary DNA strand hybridizes with Ag NCs tail strand, which can be used to identify the nucleic acid. Ag NCs with the abasic site in DNA duplex can distinguish mutant genes such as cancer suppression gene p53. Ag NCs with auxiliary DNA can be used to detect miR-21, miR-16-5p, miR-19b-3p, and miR-141. Cu NCs/Cu NPs can recognize miRNA-155, miR-21, and miR-let-7d without auxiliary DNA. Au NCs can identify H1N1 gene fragments by fluorescence quenching caused by proximity to the G-rich sequence. Besides, Au NCs can recognize miRNA-21 and let-7a. SsDNA MNCs adsorbed on the surface of GO and CNPs oxide can be used to identify HBV and HIV gene fragments. The addition of enzymes or auxiliary amplification technologies is a popular way to improve probe sensitivity. Ag NCs combined with TAIEA has the best performance and can obtain LOD as low as aM for miRNA.

Abstract
In the past few decades, biosensors have been gradually developed for the rapid detection and monitoring of human diseases. Recently, functional nucleic-acid (FNA) biosensors have attracted the attention of scholars due to a series of advantages such as high stability and strong specificity, as well as the significant progress they have made in terms of biomedical applications. However, there are few reports that systematically and comprehensively summarize its working principles, classification and application. In this review, we primarily introduce functional modes of biosensors that combine functional nucleic acids with different signal output modes. In addition, the mechanisms of action of several media of the FNA biosensor are introduced. Finally, the practical application and existing problems of FNA sensors are discussed, and the future development directions and application prospects of functional nucleic acid sensors are prospected.

DSN/TdT recycling digestion based cyclic amplification strategy for microRNA assay. Talanta 2020; 219:121173.

Abstract
Sensitive and specific detection of microRNAs (miRNAs) is of great significance for early cancer diagnosis. Here we report a simple and sensitive fluorescence signal amplification strategy that based on DSN/TdT recycling digestion for miRNA detection. DSN initiates DNA digestion on 3'-phosphate-primer/miRNA heteroduplex which causes miRNA recycle. The digested DNA strands with 3'-OH ends enable TdT to synthesize a polydeoxyguanylic tails on the 3'-end. The DNAs with polydeoxyguanylic tails are converted to double-stranded-DNA prior to initiation of DSN/TdT recycling digestion. With the cooperation of TdT and DSN, a new round of digestion and extension is triggered, leading to massive fluorophores separating and signal amplification. The amplification strategy produces large amounts of 3'-OH probes that can be used directly for dsDNA enrichment and DSN digestion. Moreover, both DSN digestion and TdT extension are sequence-independent reaction without the need of complex sequences design. In addition, this strategy is utilized to analyze miRNA samples from MCF-7 cell lysates and Cu (II) ion samples, indicating its potential application in actual sample analysis. The method shows a promising analytical platform for DNA nicking-related studies and tumor biomarkers measuring in clinical diagnostics.

Abstract
A graphene oxide (GO)-based fluorescent bioassay was developed to quantify agrA gene transcription (its mRNA) in methicillin-resistant Staphylococcus aureus (MRSA). This method is based on the use of Klenow fragment (KF)-assisted target recycling amplification and hybridization chain reaction (HCR). A triple complex was designed that contained a capture probe (CP), a trigger probe (TP), and a help probe (HP), which were partially complementary to one another. In the absence of the target, all the oligonucleotides labeled with carboxyfluorescein (FAM) are adsorbed onto the surface of GO by π-stacking interactions. This adsorption quenches the FAM signal. On the contrary, the target RNA causes the triple complex to disintegrate and initiates strand-displacement polymerization reaction (SDPR) and HCR in the presence of the appropriate raw materials, including the primer, KF, dNTPs, hairpin 1 (H1), and hairpin 2 (H2), generating double-stranded DNA (dsDNA) products. These dsDNA products are repelled by GO and produce strong fluorescence, measured at excitation/emission wavelengths of 480/514 nm. The fluorescent signal is greatly amplified by SYBR Green I (SGI) due to the synergistic effect of dsDNA-SGI. The target was assayed with this method at concentrations in the range 10 fM to 100 pM, and the detection limit (LOD) was 10 fM. This method also displayed good applicability in the analysis of real samples. It provides a new way of monitoring biofilm formation and studying the mechanisms of drug actions. Graphical abstract Schematic representation of the graphene oxide-based fluorescent bioassay for agrA gene transcription in methicillin-resistant Staphylococcus aureus by using strand-displacement polymerization recycling and hybridization chain reaction.

Abstract
Nucleic acid-based biosensors have become powerful tools in biomedical applications. But the stability issue seriously limits their wide applications. Fortunately, the emergence of carbon nanoparticles (CNPs), which can effectively protect DNA probes from enzymatic digestion and unspecific protein binding, provides a good solution. In this work, a DNase I-aided cyclic enzymatic amplification method (CEAM) for microRNA analysis has been developed based on the coupling use of nucleic acid probes with specific molecular recognition ability as well as CNPs with excellent biostability. The method is simple and sensitive, with a detection limit down to 3.2 pM. Furthermore, satisfactory results are achieved for miRNA analysis in breast cancer cell lysate, demonstrating the applicability in disease diagnosis. The ingenious combination of CNPs and nucleic acid probes can open a new chapter in the development of versatile analytical strategies that holds great potentials for clinical diagnosis, food safety, and environmental monitoring.

Abstract
A new simple, sensitive and specific strategy for microRNA analysis has been described based on a hybridization chain reaction with hemin/G-quadruplex enzymatic catalysis-induced MoS2 quantum dots via the inner filter effect. The target microRNA triggers the hybridization chain reaction between two DNA probes to generate long dsDNA with many hemin/G-quadruplex DNAzymes in the presence of hemin. With the assistance of H2O2, the produced hemin/G-quadruplex DNAzyme could oxidize o-phenylenediamine (OPD) to 2,3-diaminophenazine (DAP) directly, resulting in the fluorescence quenching of MoS2 quantum dots via the inner filter effect. As an example, the fluorescence response of MoS2 quantum dots is linearly related with the logarithm of the microRNA let-7a concentration with a detection limit of 42 fM. The proposed label-free assay has promising potential to be applied in practical diagnosis.

Abstract
MicroRNAs (miRNAs) are attractive candidates for biomarkers for early cancer diagnosis, and play vital roles in physiological and pathological processes. In this work, we developed a colorimetric and fluorescent dual-mode sensor for miRNA detection based on the optical properties of gold nanoparticles (AuNPs) and the duplex-specific nuclease (DSN)-assisted signal amplification technique. In brief, FAM labelled hairpin probes (HPs) were immobilized on AuNPs, and fluorescence was efficiently quenched by the vicinity of the fluorophores to the AuNPs surface. In the presence of target miRNAs, the HPs could specifically hybridize with miRNAs and the DNA strand in the DNA/RNA heteroduplexes could be subsequently hydrolyzed by DSN. As a result, numbers of fluorophores were released into the solution, resulting in obvious fluorescence signal recovery. Meanwhile, the target miRNAs were able to participate in other hybridization reactions. With the DSN-assisted signal amplification technique, lots of gold nanoparticles were produced with short-chain DNA on their surface, which could aggregate in salt solution and result in a colorimetric detection. The proposed dual-mode strategy offers a sensitive, accurate and selective detection method for miRNAs. One reason is that the stem of the HPs was elaborately designed to avoid hydrolyzation by DSN under optimal conditions, which ensures a relatively low background and high sensitivity. The other is that the dual-mode strategy is more beneficial for enhancing the accuracy and reproducibility of the measurements. Moreover, the unique selective-cutting ability and single-base mismatch differentiation capability of the DSN also give rise to a satisfactory selectivity. This demonstrated that the developed method could quantitatively detect miR-21 down to 50 pM with a linear calibration range from 50 pM to 1 nM, and the analytical assay of target miRNAs in cell lysate samples revealed its great potential for application in biomedical research and clinical diagnostics.

Abstract
MicroRNAs (miRNAs) are a family of endogenous, small (approximately 22 nucleotides in length), noncoding, functional RNAs. With the development of molecular biology, the research of miRNA biological function has attracted significant interest, as abnormal miRNA expression is identified to contribute to serious human diseases such as cancers. Traditional methods for miRNA detection do not meet current demands. In particular, nanomaterial-based methods, nucleic acid amplification-based methods such as rolling circle amplification (RCA), loop-mediated isothermal amplification (LAMP), strand-displacement amplification (SDA) and some enzyme-free amplifications have been employed widely for the highly sensitive detection of miRNA. MiRNA functional research and clinical diagnostics have been accelerated by these new techniques. Herein, we summarize and discuss the recent progress in the development of miRNA detection methods and new applications. This review will provide guidelines for the development of follow-up miRNA detection methods with high sensitivity and specificity, and applicability to disease diagnosis and therapy.

[PMID: 31196420 DOI: 10.1016/j.aca.2019.05.020] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 04/29/2019] [Accepted: 05/13/2019] [Indexed: 12/13/2022]
Abstract
Salmonella is a widely distributed, extremely harmful bacteria, the presence of which requires confirmation via an on-site visual biosensor. In this study, we constructed a label-free, cascade amplification visualization biosensor for the sensitive and rapid detection of Salmonella enterica subsp. enterica serovar typhimurium based on the RDTG principle (recombinase polymerase amplification (RPA), duplex-specific enzyme (DSN) cleavage, terminal deoxynucleotidyl transferase (TdT) extension and G-quadruplexes output). Following DNA extraction of Salmonella spp., the first step in the construction involved the recognition and amplification of nucleic acids, carried out by RPA, to achieve the first signal amplification within 10 min. This RPA product was then specifically cleaved by DSN to produce a large number of small double-stranded DNA (dsDNA) products with 3'-OH within 15 min to achieve the second signal amplification. Thereafter, TdT was employed to empower these small 3'-OH dsDNA products to extend and produce a large number of long G-rich single-stranded DNAs (ssDNAs) within 20 min, thus realizing the third signal increase. These long G-rich ssDNA products displayed a color change that could be directly observed through the naked eye by adding H2O2/3,3',5,5'-tetramethylbenzidine (TMB). The RDTG biosensor for the detection of Salmonella spp. has several advantages, including a low limit of 6 cfu/mL. It is an isothermal-free instrument, simple to operate, with a rapid detection time of less than 1.5 h. Furthermore, it can be visually characterized and quantified by a microplate reader to detect Salmonella spp., in food and environmental samples, and it has broad application prospects.

Abstract
During the last decades, by virtue of their unique physicochemical properties and potential application in microelectronics, biosensing and biomedicine, metal nanomaterials (MNs) have attracted great research interest and been highly developed. Deoxyribonucleic acid (DNA) is a particularly interesting ligand for templating bottom-up nanopreparation, by virtue of its excellent properties including nanosized geometry structure, programmable and artificial synthesis, DNA-metal ion interaction and powerful molecular recognition. DNA-templated copper nanoparticles (DNA-CuNPs) has been developed in recent years. Because of its advantages including simple and rapid preparation, high efficiency, MegaStokes shifting and low biological toxicity, DNA-CuNPs has been highly exploited for biochemical sensing from 2010, especially as a label-free detection manner, holding advantages in multiple analytical technologies including fluorescence, electrochemistry, surface plasmon resonance, inductively coupled plasma mass spectrometry and surface enhanced Raman spectroscopy. This review comprehensively tracks the preparation of DNA-CuNPs and its application in biosensing, and highlights the potential development and challenges regarding this field, aiming to promote the advance of this fertile research area.

Abstract
Specific nucleic acid detection in vitro or in vivo has become increasingly important in the discovery of genetic diseases, diagnosing pathogen infection and monitoring disease treatment. One challenge, however, is that the amount of target nucleic acid in specimens is limited. Furthermore, direct sensing methods are also unable to provide sufficient sensitivity and specificity. Fortunately, due to advances in nanotechnology and nanomaterials, nanotechnology-based bioassays have emerged as powerful and promising approaches providing ultra-high sensitivity and specificity in nucleic acid detection. This chapter presents an overview of strategies used in the development and integration of nanotechnology for nucleic acid detection, including optical and electrical detection methods, and nucleic acid assistant recycling amplification strategies. Recent 5 years representative examples are reviewed to demonstrate the proof-of-concept with promising applications for DNA/RNA detection and the underlying mechanism for detection of DNA/RNA with the higher sensitivity and selectivity. Furthermore, a brief discussion of common unresolved issues and future trends in this field is provided both from fundamental and practical point of view.

Abstract
Based on streptavidin coated nanospheres and T7 exonuclease assisted dual-cycle signal amplification, we developed a novel sensitive fluorescence polarization detection method for miRNA. When target miRNA was present in the system, hairpin probe hybridized with miRNA, forming a double-stranded structure. The 5' end of hairpin probe was then recognized and digested by T7 exonuclease, releasing the non-degraded single strand DNA fragments and miRNA. The released target miRNA could trigger the next cycle of hybridization and digestion, releasing more non-degraded fragments from hairpin probe. The fragments could hybridize with a signal probe (with carboxyfluorescein modification at 5'-end and biotin modification at 3'-end). The formed blunt 5'-end of signal probe was then recognized and degraded by T7 exonuclease, releasing the fragments and the fluorophore carboxyfluorescein. The next cycle of hybridization and digestion of signal probe was triggered by the released fragment at the same time. The free carboxyfluorescein cannot connect with streptavidin coated nanospheres which were used as the fluorescence polarization signal amplifier. So, there was a big change of fluorescence polarization signal after adding miRNA into the detection system, due to the different fluorescence polarization signal between nanospheres-captured intact signal probe and free carboxyfluorescein. The detection limit of this method is about 0.001 nM, and it has a good selectivity. In addition, it was also applicable to determine target miRNA in total miRNA extracts and compare the expression level of target miRNA in different cells. Consequently, the proposed method is expected to be used for the potential cancer diagnosis and the related biomedical research.

Abstract
An electrochemiluminescence (ECL) based biosensor is described for determination of microRNAs in the A549 cell line. Firstly, graphene oxide (GO) is dripped onto a glassy carbon electrode surface to form an interface to which one end of the capture probe (with a stem-loop structure) can be anchored through π-interaction via dangling unpaired bases. The other end of the capture probe is directed away from the GO surface to make it stand upright. Target microRNAs can open the hairpin structure to form a double-stranded DNA-RNA structure. Two auxiliary probes, generating a hybridization chain reaction, are used to elongate the DNA duplex. Finally, doxorubicin-modified cadmium telluride quantum dot nanoparticles (Dox-CdTe QD) are intercalated into the base pairs of the hybrid duplexes to act as signalling molecules. The ECL signal of the Dox-CdTe QD increases proportionally with the concentration of microRNAs, specifically for microRNA-21. The assay covers a wide linear range (1 fM to 0.1 nM), has a low detection limit for microRNA-21 (1 fM), and is selective, reproducible, and stable. Graphical abstract An enzyme-free amplification electrochemiluminescent assay is described to quantitative detection of microRNA in the A549 cell line. Graphene oxide was used to immobilize capture probes obviating the special modification. Doxorubicin-modified cadmium telluride quantum dot nanoparticles are intercalated into the base pairs of the hybrid duplexes to act as signalling molecules.

Abstract
The authors describe a method for the determination of microRNA-122 by using terminal deoxynucleotidyl transferase (TdT). It is based on the use of polythymine and exonuclease III-aided cycling amplification. A 3'-phosphorylated hairpin probe 1 (H1) and a hairpin probe 2 (H2) were designed. In the presence of the microRNA, hybridization and enzymatic cleavage will occur and produce lots of 3'-hydroxylated ssDNA which can be tailed by TdT and converted into long polythymine (polyT) sequences. These can be used to synthesize copper nanoparticles (CuNPs) with fluorescence excitation/emission maxima at 350 nm/630 nm. This method shows good selectivity and high sensitivity with a linear response in the 1.00 × 102 fM and 1.00 × 106 fM microRNA concentration range and a 44 fM limit of detection. It was successfully applied to determination of microRNA in spiked serum samples. Graphical abstract A label-free and highly sensitive fluorometric method is described for the assay of microRNA on the basis of target-triggered two-cycle amplification and combining with terminal TdT. It produces a series superlong polyT that can be used for synthesis of copper nanoclusters (CuNCs) displaying red fluorecence.

Abstract
Fluorescent copper nanomaterials (CuNMs), including copper nanoparticles (CuNPs) and copper nanoclusters (CuNCs), become more and more popular with the abundant raw materials and low cost. A wide range of applications has been explored due to their fascinating properties such as low toxicity, remarkable water solubility, facile synthesis, large Stokes shifts, and good biocompatibility. As a kind of genetic material, DNA exhibits its molecular recognition function and diversity. The marriage between CuNMs and DNA endows DNA-templated CuNMs (DNA-CuNMs) with unique properties such as fluorescence, electrochemiluminescence and catalytic features. In this review, we summarize the synthesis and recent applications of DNA-CuNMs. Fluorescent CuNMs can be grown on various DNA scaffolds with special sequence design. T base plays an important role in the formation of CuNMs on DNA templates. These fluorescent DNA-CuNMs hold great prospect in logic gate construction, staining and biosensing of DNAs and RNAs, ions, proteins and enzymes, small molecules and so on.

Abstract
MicroRNAs (miRNAs) diagnostics can be useful for diagnosing or confirming miRNA abundance and are used in screening tests and to assess changes in miRNAs in vivo. At present, the use of traditional nucleic acid amplification assays to detect miRNAs has been limited in laboratory environment because of the time, equipment, and technical expertise required to perform these assays. A specialized, rapid affordable miRNA detection system is necessary when there are limited resources or point-of-care testing needs. We designed a portable and affordable fluorescence-based miRNA detection system based on isothermal signal amplification technology, using SYBR Green II as a fluorescent dye. To reduce costs, we chose LED as a light source and designed the corresponding optical path for LED. The portable detection system shows results consistent with those by real-time PCR, and can be used to detect miR-183 with a limit of detection of approximately 2 fmol. We used the system to detect miR-183 in tissues and blood from patients with hepatocellular carcinoma (HCC). The results from the portable detection device were compared with those from clinical trials and indicated that the miR-183 fluorescence signal could successfully identify HCC and provide information related to cancer progression.
