Abstract
The double specific nuclease (DSN)-based methods for microRNAs (miRNAs) detection usually require the immobilization of DNA probes on a solid surface. However, such strategies have the drawbacks of low hybridization and cleavage efficiency caused by steric hindrance effect and high salt concentration on the solid surface. Herein, we proposed an immobilization-free method for miRNA detection on the basic of DSN-assisted signal amplification. The biotin- and fluorophore-labeled probes were captured by streptavidin-modified magnetic beads through streptavidin-biotin interactions, thus producing a poor fluorescence signal. Once the DNA probes were hybridized with target miRNA in solution to form DNA-miRNA duplexes, DNA stands in the duplexes would be selectively digested by DSN. The released target miRNA could initiate the next hybridization/cleavage recycling in the homogeneous solution, finally resulting in the release of numerous fluorophore-labeled fragments. The released fluorophores remained in solution and emitted strong fluorescence after treatment by the streptavidin-modified magnetic beads. The immobilization-free method achieved the assays of miRNA-21 with a detection limit down to 0.01 pM. It was employed to evaluate the expression levels of miRNA-21 in different cancer cells with satisfactory results.

A sensitive biomolecules detection device with catalytic hairpin assembly and cationic conjugated polymer-assisted dual signal amplification strategy. Talanta 2021; 223:121716. [PMID: 33303163 DOI: 10.1016/j.talanta.2020.121716] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Revised: 09/16/2020] [Accepted: 09/28/2020] [Indexed: 01/26/2023]
Abstract
A simple, sensitive, selective, and enzyme-free homogeneous fluorescent biosensing device for DNA and protein detection is fabricated based on catalytic hairpin assembly (CHA), cationic conjugated polymer (CCP), and graphene oxide (GO). In this biosensing device, CCP together with CHA, provides dual signal amplification, and GO suppresses the background when the target is absent. Thus, this CHA/CCP/GO-based biosensor shows improved sensitivity compared with conventional CHA-based biosensors. In the biosensor, two 6-carboxyfluorescein (FAM)-labeled hairpin DNA probes (H1 and H2) are designed, and in the initial state, they could absorb on the surface of GO, leading the system to produce a low background fluorescence signal. When the target DNA appears, it continually catalyzes the formation of H1-H2 double-stranded DNA (dsDNA) complex by CHA reaction, which could be regarded as the first-step amplification. At the same time, the H1-H2 dsDNA complex departures from the surface of GO and interacts with CCP through electrostatic interaction. Then, CCP provides the second-step amplification due to its high fluorescence resonance energy transfer (FRET) efficiency from CCP to FAM. The limit of detection (LOD) and the limit of quantification (LOQ) for the target DNA could reach 32 pM and 1 nM, respectively. The linear range was from 0.1 to 40 nM, and relative standard deviation (RSD) for the points on the calibration curve ranged from 2.8% to 13.9%. This strategy could also be applied to protein detection potentially by integrating the aptamer of the target protein into the hairpin DNA. As proof of concept, thrombin was detected, and the LOD and LOQ was 11 pM and 33 pM, respectively. The linear range was from 3 to 54 nM, and RSD ranged from 3.3% to 10.4%. It showed good selectivity for thrombin compared to equal concentrations of interferences. It was also applied to quantify the thrombin (5, 10, 20 nM) in 1% spiked human serum, which showed satisfying recovery in the range of 94.7 ± 5.3 to 103.7 ± 4.9%.

Sensitive monitoring of RNA transcription by optical amplification of cationic conjugated polymers. Talanta 2019; 203:314-321.

Abstract
We reported a new strategy for sensitive monitoring in vitro RNA synthesis in real time based on fluorescence resonance energy transfer (FRET) from water-soluble conjugated polymer poly (9, 9-bis (6'-N, N, N,-trimethylammonium) hexyl) fluorene-co-alt-1,4-phenylene) bromide (PFP) to fluorogenic RNA aptamer/fluorophore (Spanich2/DFHBI and Broccoli/DFHBI) system. In this strategy, RNA of interest was transcribed accompanied by the Spanich2 or Broccoli. Then the 3, 5-difluoro-4-hydroxybenzylidene imidazolinone (DFHBI) bound to the RNA aptamer sequence and thereby induced a fluorescence signal. PFP was used as the fluorescence energy donor, and Spanich2/DFHBI was the fluorescence energy acceptor. The fluorescence signal of Spanich2/DFHBI was amplified by light-harvesting and fluorescence amplification ability of PFP via FRET. And the limit of detection (LOD) (0.29 nM) was near 10-fold lower than that of RNA aptamer/DFHBI (LOD is 2.8 nM) alone by measuring the FRET ratio, which greatly reduced the variation of background signals. Most importantly, the addition of PFP did not interfere with RNA transcription in vitro, so this method was successfully applied to sensitively monitor RNA transcription and effect of T7 RNA polymerase inhibitor in real time, supplying a sensitive and simple method to study the modulation and inhibitor of RNA polymerase in vitro.

Abstract
A novel and highly sensitive method for detection of microRNA (miRNA) was developed by integration of T7 exonuclease-triggered amplification and cationic conjugated polymer (CCP) biosensing. First, a fluorescein-labeled probe was designed with the complementary sequence to the target miRNA. When target miRNA was absent in the solution, the fluorescence probe interacted with CCP through the strong electrostatic interactions, leading to the highly efficient fluorescence resonance energy transfer (FRET) from CCP to fluorescein. In the presence of target miRNA, the probe hybridized with the miRNA to form DNA/miRNA duplex hybrids. Then, T7 exonuclease digested cyclically the fluorescence probes in hybrids and triggered the enzyme amplification reaction, generating a large number of single nucleotides. Owing to the weak electrostatic interaction between CCP and the single nucleotide, the FRET from CCP to fluorescein would not take place, which effectively reduced the background and significantly enhanced the sensitivity and the dynamic range of miRNA detection. The linear range of the assay was 0.2-100 pM and the detection limit 0.08 pM was 58 times lower than that of the endonuclease-based assay. The method is simple, cost-effective, and with no need for the sophisticated instrument, and has broad application prospects for miRNA detection and early diagnosis.

Abstract
In this paper, a very simple, easily-operated and universal platform is proposed for tumor marker detection. In this strategy, tumor marker-specific aptamer, which can quench the fluorescence of polyfluorene-based cationic conjugated polyelectrolytes (PFN+), are used as recognizing probes. Upon addition of tumor marker, the aptamer can be assembled into the tumor marker-aptamer complex, resulting in fluorescence recovery of PFN+ and the detection of the targets. The most widely-used tumor markers, carcinoembryonic antigen (CEA) and fetoprotein (AFP) have been chosen as the model analytes for this work. The sensing method is capable of rapidly detect target protein within 5 min without complex handling procedure and expensive instruments. Compared with previous studies, the assay presented here is really simple and avoids either conjugated polyelectrolytes (CPEs) modification or oligonucleotide labeling. This method also shows a wide detection range of 3 orders of magnitude and the detection limit is 0.316 ng/mL for CEA and 1.76 ng/mL for AFP. Furthermore, the approach requires only a convenient"mix-and-detect" procedure and offers a universal platform for the sensitive detection of any target molecule of choice according to the selected aptamer.

Abstract
Hybridization-based probes emerge as a promising tool for nucleic acid target detection and imaging. However, the single-nucleotide selectivity is still challenging because the specificity of hybridization reaction is typically low at room temperature. We disclose an effective and simple method for highly selective detection and in situ imaging of single-nucleotide mutation (SNM) by taking the advantages of the specific hybridization of short duplex and the signal amplifying effect of cationic conjugated polymer (CCP). Excellent discrimination of the nucleic acid strands only differing by single nucleotide was achieved enabling the sensitive detection of SNM at the abundance as low as 0.1%. Single-molecule fluorescence resonance energy transfer (smFRET) study reveals that the presence of CCP enhances the perfect matched duplex and the mismatched duplex to a different extent, which can be an explanation for the high single-nucleotide selectivity. Due to the simple design of the probe and the stable brightness of CCP, highly selective mRNA in situ imaging was achieved in fixed cells. Melanoma cell line A375 with BRAF V600E point mutation exhibits higher FRET efficiency than liver cancer cell line HegG2 that was not reported having the mutation at this point.

Abstract
Biofuel cell (BFC)-based self-powered biosensors have attracted substantial attentions because of their unique merits such as having no need for power sources (only two electrodes are needed). More importantly, in case it can also work in a homogeneous system, more efficient and easy-to-use bioassays could come true. Thus, herein, we proposed a novel homogeneous self-powered biosensing strategy via the integration of BFCs and a homogeneous electrochemical method, which was further utilized for ultrasensitive microRNA (miRNA) detection. To construct such an assay protocol, the cathodic electron acceptor [Fe(CN)6]3- was entrapped in the pores of positively charged mesoporous silica nanoparticles and capped by the biogate DNAs. Once the target miRNA existed, it would trigger the controlled release of [Fe(CN)6]3-, leading to the dramatic increase of the open circuit voltage. Consequently, the "signal-on" homogeneous self-powered biosensor for the ultrasensitive miRNA assay was realized. Encouragingly, the limit of detection for the miRNA-21 assay was down to 2.7 aM (S/N = 3), obviously superior to those of other analogous reported approaches. This work not only provides an ingenious idea to construct the ultrasensitive and easy-to-use bioassays of miRNA but also exhibits a successful prototype of a portable and on-site biomedical sensor.

Abstract
Identifying the microRNA (miRNA) expression level can provide critical information for early diagnosis of cancers or monitoring the cancer therapeutic efficacy. This paper focused on a kind of gold-nanoparticle-coated polystyrene microbeads (PS@Au microspheres)-based DNA probe as miRNA capture and duplex-specific nuclease (DSN) signal amplification platform based on an RGB value readout for detection of miRNAs. In virtue of the outstanding selectivity and simple experimental operation, 5'-fluorochrome-labeled molecular beacons (MBs) were immobilized on PS@Au microspheres via their 3'-thiol, in the wake of the fluorescence quenching by nanoparticle surface energy transfer (NSET). Target miRNAs were captured by the PS@Au microspheres-based DNA probe through DNA/RNA hybridization. DSN enzyme subsequently selectively cleaved the DNA to recycle the target miRNA and release of fluorophores, thereby triggering the signal amplification with more free fluorophores. The RGB value measurement enabled a detection limit of 50 fM, almost 4 orders of magnitude lower than PS@Au microspheres-based DNA probe detection without DSN. Meanwhile, by different encoding of dyes, miRNA-21 and miRNA-10b were simultaneously detected in the same sample. Considering the ability for quantitation, high sensitivity, and convenient merits, the PS@Au microspheres-based DNA probe and DSN signal amplification platform supplied valuable information for early diagnosis of cancers.

Abstract
Optical/MRI bimodal probes have attracted much attention due to palmary soft tissue resolution and high imaging sensitivity. In this study, poly[fluorene-co-alt-p-phenylene] containing organic radical (PFP-TEMPO+) is successfully developed for optical and MRI dual-modality bioimaging. PFP-TEMPO+ displays advanced properties such as fluorescence emission, high photostablilty, reasonable T1 relaxation effect, low cytotoxicity, and good biocompatibility. Moreover, the ability of PFP-TEMPO+ for tumor tissues imaging confirms that it could be used as an optical and MRI imaging probe for in vivo imaging. The results of the present work disclose the potential applications of PFP-TEMPO+ as an optical and MRI contrast agent.

Abstract
MicroRNAs (miRNAs) serve as diagnostic and prognostic biomarkers for a wide variety of cancers. Via the novel conjugates of gold nanoparticle-coated magnetic microbeads (AuNP-MMBs) and the diblock oligonucleotide (ODN)-modified AuNPs, multiplexed electrochemical assay of miRNAs was performed. The hybridization to target miRNAs leads to the conformational change of the hairpin-structured ODN probes, and the attachment of the diblock ODN-modified AuNPs was achieved. By examining the oxidation peak currents of methylene blue (MB) and ferrocene (Fc) moieties residing on the diblock ODNs, simultaneous quantification of miRNA-182 and miRNA-381 was conducted. The detection signals were significantly enhanced due to the numerous MB and Fc tags on the AuNPs. The proposed assay was highly selective for discriminating miRNAs with similar sequences, and detection limits of 0.20 fM and 0.12 fM for miRNA-182 and miRNA-381, respectively, were achieved. The feasibility of the method for sensitive determination of miRNA-182 and miRNA-381 from serum samples of glioma patients at different stages was demonstrated. The sensing protocol thus holds great potential for early diagnosis and treatment of cancer patients.

Abstract
A novel, label-free and convenient strategy for thrombin assay has been developed based on the fluorescence resonance energy transfer (FRET) from a cationic conjugated polymer (CCP) to Ir(III) complex. The energy donor (CCP) and acceptor (Ir(III) complex) were taken into close proximity through π-π stacking interaction and electrostatic interaction, leading to the occurrence of FRET. However, the introduction of the thrombin aptamer upset the status and blocked the FRET process, but afterwards the reappearance of FRET phenomenon was confirmed by the special binding interaction between aptamer and thrombin, thus achieving the quantitative detection of thrombin. This assay could detect thrombin as low concentration as about 0.05pM and provided a highly specific selectivity among other nonspecific proteins. Moreover, the strategy may allow our platform to provide similar sensitivity toward different targets in an aptamer-structure-independent manner. Furthermore, the assay can be used to detect thrombin in diluted real urine or serum samples with a satisfactory recovery, implying its great potential for rapid detection of thrombin in the clinic.

Abstract
miRNAs have emerged as new biomarkers for the detection of a wide variety of cancers. By employing duplex-specific nuclease for signal amplification and gold nanoparticles (AuNPs) as the carriers of detection probes, a novel electrochemical assay of miRNAs was performed. The method is based on conversion of the well-known colorimetric assay into electrochemical analysis with enhanced sensitivity. DNA capture probes immobilized on the electrode surface and ferrocene (Fc)-labeled DNA detection probes (denoted "Fc-DNA-Fc") presented in the solution induced the assembly of positively charged AuNPs on the electrode surface through the electrostatic interaction. As a result, a large number of Fc-DNA-Fc molecules were attached on the electrode surface, thus amplifying the electrochemical signal. When duplex-specific nuclease was added to recycle the process of miRNA-initiated digestion of the immobilized DNA probes, Fc-DNA-Fc-induced assembly of AuNPs on the electrode surface could not occur. This resulted in a significant fall in the oxidation current of Fc. The current was found to be inversely proportional to the concentration of miRNAs in the range of 0-25 fM, and a detection limit of 0.1 fM was achieved. Moreover, this work presents a new method for converting colorimetric assays into sensitive electrochemical analyses, and thus would be valuable for design of novel chemical/biosensors.

Abstract
In recent years, the analytical application of logical nanodevices has attracted much attention for making accurate decisions on molecular diagnosis. Herein, a DNA domino-based nanoscale logic circuit has been constructed by integrating three logic gates (AND-AND-YES) for simultaneous analysis of multiple nucleic acid biomarkers. In the first AND gate, a chimeric target DNA comprising of four biomarkers was hybridized to three biomarker-specific oligonucleotides (TRs) via their 5'-end regions and to a capture probe-magnetic microparticle. After harvesting the complex, 3' overhang regions of the TRs were labeled with three distinct monolayer double-stranded (ds) DNA-gold nanoparticles (DNA-AuNPs). Upon gleaning the complex and addition of initiator oligonucleotide, a series of toehold-mediated strand displacement reactions, which are reminiscent of a domino chain, spontaneously occurred between the confined dsDNAs on the nanoparticles' surface in the second AND gate. The output of the second gate entered into the last gate and triggered an exponential hairpin assembly to form four-way junction nanostructures. The resulting nanostructures bear split parts of DNAzyme at each end of the four arms which, in the presence of hemin, form catalytic hemin/G-quadruplex DNAzymes with peroxidase activity. The smart biosensor has exhibited a turn-on signal when all biomarkers are present in the sample. In fact, should any of the biomarkers be nonexistent, the signal remains turned-off. The biosensor can detect the biomarkers with a LOD value of 100 aM and a noticeable capability to discriminate single-nucleotide substitutions.

Abstract
We present a universal amplified-colorimetric for detecting nucleic acid targets or aptamer-specific ligand targets based on gold nanoparticle-DNA (GNP-DNA) hybridization chain reaction (HCR). The universal arrays consisted of capture probe and hairpin DNA-GNP. First, capture probe recognized target specificity and released the initiator sequence. Then dispersed hairpin DNA modified GNPs were cross-linked to form aggregates through HCR events triggered by initiator sequence. As the aggregates accumulate, a significant red-to purple color change can be easily visualized by the naked eye. We used miRNA target sequence (miRNA-203) and aptamer-specific ligand (ATP) as target molecules for this proof-of-concept experiment. Initiator sequence (DNA2) was released from the capture probe (MNP/DNA1/2 conjugates) under the strong competitiveness of miRNA-203. Hairpin DNA (H1 and H2) can be complementary with the help of initiator DNA2 to form GNP-H1/GNP-H2 aggregates. The absorption ratio (A620/A520) values of solutions were a sensitive function of miRNA-203 concentration covering from 1.0 × 10-11 M to 9.0 × 10-10 M, and as low as 1.0 × 10-11 M could be detected. At the same time, the color changed from light wine red to purple and then to light blue have occurred in the solution. For ATP, initiator sequence (5'-end of DNA3) was released from the capture probe (DNA3) under the strong combination of aptamer-ATP. The present colorimetric for specific detection of ATP exhibited good sensitivity and 1.0 × 10-8 M ATP could be detected. The proposed strategy also showed good performances for qualitative analysis and quantitative analysis of intracellular nucleic acids and aptamer-specific ligands.

Abstract
Superstructural assembly of magnetic nanoparticles enables approaches to biosensing by combining specially tailored properties of superstructures and the particular advantages associated with a magnetic or optomagnetic read-out such as low background signal, easy manipulation, cost-efficiency, and potential for bioresponsive multiplexing. Herein, we demonstrate a sensitive and rapid miRNA detection method based on optomagnetic read-out, duplex-specific nuclease (DSN)-assisted target recycling, and the use of multilayer core-satellite magnetic superstructures. Triggered by the presence of target miRNA and DSN-assisted target recycling, the core-satellite magnetic superstructures release their "satellites" to the suspension, which subsequently can be quantified accurately in a low-cost and user-friendly optomagnetic setup. Target miRNAs are preserved in the cleaving reaction and can thereby trigger more cleavage and release of "satellites". For singleplex detection of let-7b, a linear detection range between 10 fM and 10 nM was observed, and a detection limit of 4.8 fM was obtained within a total assay time of 70 min. Multiplexing was achieved by releasing nanoparticles of different sizes in the presence of different miRNAs. The proposed method also has the advantages of single-nucleotide mismatch discrimination and the ability of quantification in a clinical sample matrix, thus holding great promise for miRNA routine multiplex diagnostics.
