An integrated liposome-based microfluidic strategy for rapid colorimetric analysis: A case study of microRNA-21 detection. Talanta 2024; 272:125838. [PMID: 38430866 DOI: 10.1016/j.talanta.2024.125838] [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: 12/28/2023] [Revised: 02/21/2024] [Accepted: 02/25/2024] [Indexed: 03/05/2024]
Abstract
In this study, a novel integrated liposome-based microfluidic platform combined with a smartphone was designed for the rapid colorimetric detection of microRNA-21 (miRNA-21) in real samples. The flowing surface-functionalized liposomes were first captured by nucleic acid-functionalized Au nanoparticles in the microfluidic chip. In the presence of miRNA-21, the DNA strand modified on the surface of Au nanoparticles hybridized with the target to form double-stranded products and was cleaved by duplex-specific nuclease (DSN) enzyme, causing the liposomes to be re-released. Then, as the liposomes in the colorimetric module were lysed and the "cellular" contents were released, a step-by-step "glucose-glucose oxidase-3,3',5,5'-tetramethylbenzidine (TMB)" colorimetric reaction process catalyzed by the G-quadruplex/hemin was triggered. The grayscale values were recorded and recognized by the smartphone camera for miRNA-21 analysis. The advantages of the present strategy included the portability of smartphone-based colorimetric assay, the encapsulation and transport of reactants by liposomes and the low solvent usage of microfluidic chip. Under optimal conditions, this assay exhibited a wide linear range from 1 pM to 1 nM (r2 = 0.9981), and the limit of detection of miRNA-21 was as low as 0.27 pM. Moreover, the high specificity of this strategy allowed its successful application to the rapid analysis of miRNA-21 in real blood serum samples of people with type 2 diabetes.

Abstract
DNA methylation is the process by which specific bases on a DNA sequence acquire methyl groups under the catalytic action of DNA methyltransferases (DNMT). Abnormal changes in the function of DNMT are important markers for cancers and other diseases; therefore, the detection of DNMT and the selection of its inhibitors are critical to biomedical research and clinical practice. DNA molecules can undergo intermolecular assembly to produce functional aggregates because of their inherently stable physical and chemical properties and unique structures. Conventional DNMT detection methods are cumbersome and complicated processes; therefore, it is necessary to develop biosensing technology based on the assembly of DNA nanostructures to achieve rapid analysis, simple operation, and high sensitivity. The design of the relevant program has been employed in life science, anticancer drug screening, and clinical diagnostics. In this review, we explore how DNA assembly, including 2D techniques like hybridization chain reaction (HCR), rolling circle amplification (RCA), catalytic hairpin assembly (CHA), and exponential isothermal amplified strand displacement reaction (EXPAR), as well as 3D structures such as DNA tetrahedra, G-quadruplexes, DNA hydrogels, and DNA origami, enhances DNMT detection. We highlight the benefits of these DNA nanostructure-based biosensing technologies for clinical use and critically examine the challenges of standardizing these methods. We aim to provide reference values for the application of these techniques in DNMT analysis and early cancer diagnosis and treatment, and to alert researchers to challenges in clinical application.

Abstract
DNA methylation plays an important role in epigenetic modification. DNA methyltransferase (DNMT) is essential in the DNA methylation process, and its abnormal expression is closely related to cancer. In this study, we propose a novel biosensor platform (DS-GlaI-EXPAR) that combines hemi-methylated double-stranded DNA (dsDNA) as the substrate for DNMT1 with GlaI-assisted isothermal exponential amplification reaction (EXPAR) for rapid, simple, and sensitive detection of DNMT1 activity. The hemi-methylated dsDNA is fully methylated by DNMT1, and GlaI recognizes and cleaves the fully methylated sequence, generating terminal fragments that trigger EXPAR for efficient signal amplification. Whereas hemi-methylated dsDNA without DNMT1 will keep intact and cannot initiate EXPAR. DNMT1 activity can therefore be sensitively quantified by the real-time fluorescence signal of the DS-GlaI-EXPAR platform. The high-efficiency amplification of EXPAR and the recognition of GlaI enable the platform to overcome the inherent cumbersome and time-consuming shortcomings of traditional methods while meeting specificity and sensitivity. This DS-GlaI-EXPAR platform offers an impressively low limit of detection of 0.86 pg/μL and the entire detection process can be completed in a short time of 2.5 h in a single tube. Furthermore, DNMT1 activity detected by this platform in MCF-7 cells was significantly higher than that of HEK293 cells, and the inhibition of Apt. #9 was verified. This DNMT1 activity detection platform is very convenient and effective for the discovery of inhibitors and early cancer diagnosis.

Abstract
The abnormal expression of human DNA methyltransferases (DNMTs) is closely related with the occurrence and development of a wide range of human cancers. DNA (cytosine-5)-methyltransferase-1 (DNMT1) is the most abundant human DNA methyltransferase and is mainly responsible for genomic DNA methylation patterns. Abnormal expression of DNMT1 has been found in many kinds of tumors, and DNMT1 has become a valuable target for the diagnosis and drug therapy of diseases. Nowadays, DNMT1 has been found to be involved in multiple cancers such as pancreatic cancer, breast cancer, bladder cancer, lung cancer, gastric cancer and other cancers. In order to achieve early diagnosis and for scientific research, various analytical methods have been developed for qualitative or quantitative detection of low-abundance DNMT1 in biological samples and human tumor cells. Herein, we provide a brief explication of the research progress of DNMT1 involved in various cancer types. In addition, this review focuses on the types, principles, and applications of DNMT1 detection methods, and discusses the challenges and potential future directions of DNMT1 detection.

Abstract
Artificial solid-state nanochannels have aroused intense interests in biosensors and bioelectronics because of their special architectures. Herein, we pioneered an ingenious approach of target-triggered cascade signal amplification in porous anodic aluminum oxide (AAO) nanochannels for ultrasensitive photoelectrochemical (PEC) DNA bioanalysis. In the design, AAO nanochannels were modified initially with capture DNA (cDNA) and then incorporated with a photoelectrode, yielding the desired architecture of highly ordered nanoarrays on top of the signal transducer. For target DNA (tDNA) probing, exonuclease III (Exo-III) mediated target recycling (ETR) was first activated to generate plenty of output DNA (oDNA) fragments. After oDNA and the conjugate of Au-labeled probe DNA (Au-pDNA) were anchored within the nanochannels via DNA hybridization, in-situ synthesis of Ag shells on tethered Au nanoparticles was conducted. The resulting large-sized Au@Ag core-shell nanostructure within the nanochannels would cause conspicuous blocking effect to hinder the transportation of electrons accessing the photoelectrode. Since the signal inhibition was directly related to tDNA concentration, an innovative nanochannels PEC DNA assay was exploited and qualified for ultrasensitive detection. The anti-interference ability of this platform was also emphasized by the split AAO membrane for biological incubation without participation of the photoelectrode. This featured nanochannels PEC strategy with cascade amplification launched a novel detecting platform for trace levels of DNA, and it could spark more inspiration for a follow-up exploration of other smart nanochannels PEC bioassays.

Abstract
DNA methylation catalyzed by DNA adenine methylation methyltransferase (Dam MTase) is strongly connected with a variety of biological processes, hence, monitoring Dam MTase activity is of great importance. Here, we developed a rapid and sensitive fluorescence sensing strategy for the detection of Dam MTase activity based on methylation-blocked enzymatic recycling amplification. In this fluorescence sensing system, Dam MTase-induced methylation blocked the subsequent reactions. In contrast, in the absence of Dam MTase, the unmethylated probe initiated the cascade strand displacement amplification for significant signal amplification. Under optimized conditions, this method has a lower detection limit of 0.67 U/mL and a shorter assay time (90 min) compared with previously reported similar methodologies.

Abstract
DNA methylation is an essential genomic epigenetic behavior in both eukaryotes and prokaryotes. Deregulation of DNA methyltransferase (Dam MTase) can change the DNA methylation level and cause various diseases. Herein, we develop an apurinic/apyrimidinic endonuclease 1 (APE1)-mediated cascade signal amplification platform for homogeneously sensitive and rapid measurement of Dam MTase in Escherichia coli cells. This assay involves a partial double-stranded DNA (dsDNA) substrate and two hairpin signal probes (HP1 and HP2) that are modified with Cy5 and BHQ2 at two ends, respectively. When Dam MTase is present, it methylates the dsDNA substrate, and subsequently, endonuclease DpnI cleaves the methylated substrate, yielding trigger probe 1. Hybridization of trigger probe 1 with HP1 forms a partial dsDNA containing an apurinic/apyrimidinic (AP) site, which is cleaved by APE1 to induce the cyclic cleavage of HP1 and the production of abundant trigger probe 2. Subsequent hybridization of trigger probe 2 with HP2 forms a partial dsDNA with an AP site, inducing the cyclic cleavage of HP2 by APE1. Consequently, cyclic cleavage of HP1 and HP2 induces the generation of abundant Cy5 molecules, which are easily measured by single-molecule imaging. This assay can be performed homogeneously and rapidly within 2 h, which is the shortest among the reported amplification-based assays. Moreover, it exhibits good selectivity and high sensitivity, and it can discriminate Dam MTase from other enzymes and screen inhibitors. Importantly, it can accurately measure the Dam MTase activity in serum and E. coli cells, with promising applications in clinical diagnosis and drug discovery.

Abstract
The human epidermal growth factor receptor 2 (HER-2) protein is a member of the epidermal growth factor receptor (EGFR or ErbB) family and is a transmembrane tyrosine kinase receptor. HER-2 is highly regulated in ovarian, lung, gastric, oral, and breast cancers. The low specificity, complexity, expensiveness and the lack of sensitivity are essential restrictions in traditional diagnosis methods such as FISH, immunohistochemistry and PCR and these disadvantages led to the need for more studies on alternative methods. Biosensor technology has greatly affected the quality of human life owing to its features including, sensitivity, specificity, and rapid diagnosis and monitoring of different patient diseases. In this review article, we examine various biosensors, considering that they have been categorized based on the transducers used including piezoelectric biosensors, optical sensors such as fluorescence and surface plasmon resonance, and electrochemical types for the diagnosis of HER-2 and the effectiveness of some drugs against that. Attention to developing some types of biosensor devices such as colorimetric biosensors for HER-2 detection can be an important point in future studies.

Abstract
A sensitive and ratiometric electrochemical biosensor was developed for the determination of dimethoate via alkaline phosphatase (ALP) mediated dissolution of nano-MnO2 and [Ru(NH3)6]3+(Ru(III)) redox recycling. The electroactive probe Ru(III) was adsorbed on the nano-MnO2 with the high specific surface area through electrostatic interaction to form the MnO2-Ru(III) nanocomposite, which was then fixed on the surface of the glassy carbon electrode. When the dimethoate inhibited the catalytic activity of ALP in a homogeneous system, the hydrolysate L-ascorbic acid (AA) produced by ALP hydrolysis of L-ascorbic acid-trisodium 2-phosphate (AAP) decreased. The solution was then incubated with a glassy carbon electrode modified by MnO2-Ru(III). At this time, only a small amount of MnO2-Ru(III) was decomposed and Ru(III) was rapidly electroreduced to Ru(II) on the surface of the electrode. The in-situ produced Ru(II) was chemically oxidized back to Ru(III) by Fe(III). The redox recycling of Ru(III) was completed and the Ru(III) reduction current signal was amplified. The process consumed part of Fe(III) to reduce the reduction current signal of Fe(III), and the ratio of the two reduction currents (IRu(III)/IFe(III)) increased significantly. The IRu(III)/IFe(III) value increased with the increase of dimethoate concentration in the linear range of 0.01-300 ng mL-1, and the detection limit was 6.3 pg mL-1. It has been successfully applied to the determination of dimethoate in oilseed rape and lettuce with a satisfactory result.

Abstract
DNA (cytosine-5)-methyltransferase1 (DNMT1) is the most abundant DNA methyltransferase in somatic cells, and it plays an important role in the initiation, occurrence, and rehabilitation of tumors. Herein, we developed a novel strategy for the detection of the level of DNMT1 in human plasma using the self-assembled nucleic acid probe signal amplification technology. In this method, the DNMT1 monoclonal antibody (McAbDNMT1) was immobilized on carboxyl magnetic beads to form immunomagnetic beads and then captured DNMT1 specifically. After that, DNMT1 polyclonal antibody (PcAbDNMT1) and biotinylated sheep anti-rabbit IgG (sheep anti rabbit IgG-Biotin) were sequentially added into the system to react with DNMT1 and form biotinylated double antibody sandwich immunomagnetic beads. In the presence of the bridging medium streptavidin, the biotinylated double antibody sandwich immunomagnetic beads would form a complex with biotinylated poly-fluorescein (Biotin-poly FAM), and the fluorescence intensity of the complex was proportional to the concentration of DNMT1. Immunomagnetic beads can capture the target DNMT1 in the sample, and Biotin-poly FAM can realize signal amplification. Using these strategies, we got a linear range of the system for DNMT1 level detection was from 2 nmol/L to 200 nmol/L, and the limit of detection (LOD) was 0.05 nmol/L. The method was successfully applied for the determination of DNMT1 in human plasma with the recovery of 101.3-106.0%. Therefore, this method has the potential for the detection of DNMT1 level in clinical diagnosis.

Abstract
Clustered regularly interspaced short palindromic repeats, CRISPR, has recently emerged as a powerful molecular biosensing tool for nucleic acids and other biomarkers due to its unique properties such as collateral cleavage nature, room temperature reaction conditions, and high target-recognition specificity. Numerous platforms have been developed to leverage the CRISPR assay for ultrasensitive biosensing applications. However, to be considered as a new gold standard, several key challenges for CRISPR molecular biosensing must be addressed. In this paper, we briefly review the history of biosensors, followed by the current status of nucleic acid-based detection methods. We then discuss the current challenges pertaining to CRISPR-based nucleic acid detection, followed by the recent breakthroughs addressing these challenges. We focus upon future advancements required to enable rapid, simple, sensitive, specific, multiplexed, amplification-free, and shelf-stable CRISPR-based molecular biosensors.

Abstract
The MWCNTs/Fe3O4@TMU-21 as a novel electrochemical sandwich-type genosensor was fabricated to detect the BRCA1 gene using the redox-cycling ferrocene functionalized reporter label probe (r-Fc-DNA). In the designed genosensor, the capture probe (cDNA) and r-Fc-DNA were used to detect the BRCA1 gene in sandwich-type genosensor, in which DNA sequences are well -hybridized with the BRCA1 gene (t-DNA). The cDNA was immobilized on the multiwall carbon nanotube and metal-organic framework with Fe3O4 nanoparticle core, which is the sensor platform. Target DNA was assayed by redox-recycling reporter probe (r-Fc-DNA) using the electro-catalytic activity of ferri/ferrocyanide, which results in significantly enhanced the oxidation peak current of r-Fc-DNA. The electrochemical redox cycling led to a high signal-to-noise ratio for gene assay. MWCNTs and Fe3O4@TMU-21 were applied to increase the platform conductivity and suitable binding of the recognition elements. This constructed genosensor plays an influential role in increasing the sensitivity of BRCA1 gene sequence recognition. So that under optimal conditions, this genosensor illustrated a wide linear range from 1.0×10-15 to 1.0×10-10 M with a detection limit of 0.57 × 10-15 M. Moreover, the genosensor exhibited high selectivity, stability, and reproducibility. The obtained recoveries (between 91 and 105%) of the BRCA1 gene assay in human blood samples satisfactory, which can be used for BRCA1 gene measurement in the laboratory.

Abstract
DNA methyltransferase (MTase), modulating the level of genomic DNA methylation, harbors both a pharmacological target for clinical therapy and a potential biomarker for genetic disorders and tumorigenesis. Typical homogeneous electrochemical approaches, employing solution phase probes, have been considered simple, efficient, and economical method, yet these architectures usually require electroactive molecules labeling, rely on weak electrostatic adsorption interaction, and possess low sensitivity. For circumventing the above drawbacks, herein, we devise a 'plug and play' microelectrode featuring microminiaturization, rapid response time and enhanced mass transport to quantify MTase activity through monitoring the variation of diffusion current of methylene blue (MB) induced by the less-mobile G-quadruplex framework. By coupling the unique signal-transduction approach with Y-motif-mediated primer-free cyclic signal amplification (YPCSA), the miniaturized biosensor possesses low detection limit (down to 2.5 × 10-4 U mL-1), high specificity, good stability and satisfying reusability, and has been successfully applied to the screening of MTase inhibitors, holding great potential in clinical diagnosis and pharmacological research.

Abstract
An effective signal amplification strategy is essential to enhance the analytical performance of microfluidic paper-based analytical devices (μPADs) for tracing biomarkers. Here, a simple but efficient approach with superior electrocatalytic performance of Pd@hollow Zn/Co core-shell ZIF67/ZIF8 nanoparticles for regulating the efficacious signal amplification process was utilized to realize the detection of prostate-specific antigen (PSA). By rationally designing the core-shell structure of ZIF67/ZIF8 with hollow characteristics on the nanoscale and introducing the noble metal element Pd into the cavity, the diffusion limitation and porous confinement reduction of the obtained nanomaterials with uniform morphology and satisfactory chemical stability could be realized, which endowed it with better catalytic performance than solid metal-organic frameworks (MOFs) and ensured effective signal amplification of H2O2 reduction for achieving enhanced electrochemical signals. Moreover, with the assistance of signal probes, the remaining H2O2 could flow to the color area to catalyze the oxidation of 3,3',5,5'-tetramethylbenzidine to form a colored product by changing the spatial configuration of the μPAD, thus realizing the visual detection of PSA. On the basis of this novel analytical device, dual-mode ultrasensitive detection of PSA could be achieved with a lower limit of detection of 0.78 pg/mL (S/N = 3) and a wider linear range from 5 pg/mL to 50 ng/mL. This work provided the opportunity of introducing the noble metal element Pd into the cavity of the MOF hollow structure to improve its electrocatalytic efficiency and construct a high-performance μPAD for clinical detection of other biomarkers.

Abstract
Tumor exosomes are promising biomarkers for early cancer diagnosis in a noninvasive manner. However, precise capture and direct analysis of tumor-specific exosomes in complex biological samples are still challenging. Herein, we present a highly efficient dual-aptamer recognition system for precisely isolating and quantifying tumor exosomes from the complex biological environment based on hyperbranched DNA superstructure-facilitated signal amplification and ratiometric dual-signal strategies. When tumor exosomes were captured by the dual-aptamer recognition system, the cholesterol-modified DNA probe was anchored on the surface of the exosomes, activating DNA tetrahedron-based hyperbranched hybridization chain reaction to generate a sandwich complex. Then, the sandwich complex could bind a large number of Ru(NH3)63+ (Ru(III)), leading to a small amount of unbound Ru(III) left in the supernatant after magnetic separation. Hence, the redox reaction between Ru(II) and [Fe(CN)6]3- (Fe(III)) was significantly prevented, causing an obviously enhanced IFe(III)/IRu(III) value. Consequently, highly sensitive detection of tumor exosomes was achieved. The developed approach successfully realized direct isolation and analysis of tumor exosomes in complex sample media and human serum samples as well. More significantly, this ratiometric dual-signal mode and immobilization-free strategy effectively circumvented the systematic errors caused by external factors and the tedious probe immobilization processes, thus displaying the excellent performances of high reliability, improved accuracy, and easy manipulation. Overall, this approach is expected to offer novel ways for nondestructive early cancer diagnosis.

Abstract
Detection of methyltransferase (MTase) activity is of great significance in methylation-related disease diagnosis and drug screening. Herein, we present a dual-amplification sensing strategy that is assisted by plasmonically enhanced Raman intensity at engineered nanoholes array, along with signal amplification by the hybridization chain reaction (HCR) for the ultrasensitive detection of M.SssI MTase activity and inhibitor screening. An engineered surface-enhanced Raman scattering (SERS) substrate, namely, a structured nanoholes array (NHA) with wavelength-matched surface plasmon resonance (SPR) at the wavelength of laser excitation (785 nm), was rationally designed through finite-difference time-domain (FDTD) simulations, precisely fabricated through master-assisted replication, and then used as a sensing platform. Uniform and intense SERS signals were achieved by turning on the plasmonic enhancement under the excitation of SPR. Probe DNA was designed to hybridize with target DNA (a BRCA1 gene fragment), and the formed dsDNA with the recognition site of M.SssI was assembled on the NHA. In the presence of M.SssI, the HCR process was triggered upon adding DNAs labeled with the Raman reporter Cy5, leading to an amplified SERS signal of Cy5. The intensity of Cy5 increases with increasing M.SssI activity, which establishes the basis of the assay for M.SssI. The developed assay displays an ultrasensitivity that has a broad linear range (0.002-200 U/mL) and a low detection limit (2 × 10-4 U/mL), which is superior to that of the reported SERS-based detection methods. Moreover, it can selectively detect M.SssI in human serum samples and evaluate the efficiency of M.SssI inhibitors.

Abstract
DNA methylation at cytosine/guanine dinucleotide islands (CpGIs) is the most prominent epigenetic modification in prokaryotic and eukaryotic genomes. DNA methyltransferases (MTases) are responsible for genomic methylation, and their aberrant activities are closely associated with various diseases including cancers. However, the specific and sensitive detection of multiple DNA MTases has remained a great challenge due to the specificity of the methylase substrate and the rareness of methylation-sensitive restriction endonuclease species. Here, we demonstrate for the first time the cytosine-5 methylation-directed construction of a Au nanoparticle (AuNP)-based nanosensor for simultaneous detection of multiple DNA MTases at the single-molecule level. We used the methyl-directed endonuclease GlaI to cleave the site-specific 5-methylcytosine (5-mC). In the presence of CpG and GpC MTases (i.e., M.SssI and M.CviPI), their hairpin substrates are methylated at cytosine-5 to form the catalytic substrates for GlaI, respectively, followed by simultaneous cleavage by GlaI to yield two capture probes. These two capture probes can hybridize with the Cy5/Cy3-signal probes which are assembled on the AuNPs, respectively, to form the double-stranded DNAs (dsDNAs). Each dsDNA with a guanine ribonucleotide can act as the catalytic substrate for ribonuclease (RNase HII), inducing recycling cleavage of signal probes to liberate large numbers of Cy5 and Cy3 molecules from the AuNPs. The released Cy5 and Cy3 molecules can be simply quantified by total internal reflection fluorescence (TIRF)-based single-molecule imaging for simultaneous measurement of M.SssI and M.CviPI MTase activities. This method exhibits good specificity and high sensitivity with a detection limit of 2.01 × 10-3 U mL-1 for M.SssI MTase and 3.39 × 10-3 U mL-1 for M.CviPI MTase, and it can be further applied for discriminating different kinds of DNA MTases, screening potential inhibitors, and measuring DNA MTase activities in human serum and cell lysate samples, holding great potential in biomedical research, clinical diagnosis, drug discovery and cancer therapeutics.

Abstract
Surface-enhanced Raman spectroscopy (SERS), which utilizes nanogaps between noble-metal nanostructures as hot spots to yield ultrasensitive SERS signals, is an outstanding label-free and straightforward tool for DNA methylation analysis. Herein, a plasmonic gold nanohole array (PGNA) with well-controlled hot spots and an open surface was designed as a SERS substrate for DNA methylation detection. A finite-difference time-domain (FDTD) simulation was first employed to investigate the electric field distributions of the PGNA as a function of the geometric parameters. The plasmonic response was tuned to 785 cm-1 to match the ring breathing vibrational band of cytosine, the intensity change of which was revealed to be a marker of DNA methylation. Then, guided by the FDTD simulation results, the PGNA was fabricated via the electron beam lithography (EBL) technique. The fabricated PGNA had an open and easily accessible surface topology, a SERS enhancement factor of ∼106, and a relative standard deviation (RSD) of 7.1% for 500 repetitions over an area of 20 × 20 μm2 using 1 μM Rhodamine 6G as the Raman reporter. The fabricated PGNA was further used as a platform for determining DNA methylation. The proposed method exhibited a sensitivity for detecting 1% of methylation changes. Moreover, insight into the dynamic information on methylation events was obtained by combining principal component analysis (PCA) with 2D correlation spectroscopy analysis. Finally, clear discrimination of the different methylation sites, such as 5-methylcytosine and N6-methyladenine, was demonstrated.

Abstract
DNA methylation is a significant epigenetic mechanism involving processes of transferring a methyl group onto cytosine or adenine. Such DNA modification catalyzed by methyltransferase (MTase) plays important roles in the modulation of gene expression and other cellular activities. Herein, we develop a simple and sensitive biosensing platform for the detection of DNA MTase activity by using only two oligonucleotides. The fluorophore labeled molecular beacon (MB) can be methylated by MTase and subsequently cleaved by endonuclease DpnI at the stem, giving a shortened MB. The shortened MB can then hybridize with a primer DNA, initiating a cycle of strand displacement amplification (SDA) reactions. The obtained SDA products can unfold new MB and initiate another cycle of SDA reaction. Therefore, continuous enlargement of SDA and exponential amplification of the fluorescence signal are achieved. Because the triple functions of substrate, template and probe are elegantly integrated in one oligonucleotide, only two oligonucleotides are necessary for multiple amplification cycles, which not only reduces the complexity of the system, but also overcomes the laborious and cumbersome operation that is always a challenge in conventional methods. This platform exhibits an extremely low limit of detection of 3.3 × 10-6 U mL-1, which is the lowest to our knowledge. The proposed MTase-sensing platform was also demonstrated to perform well in a real-time monitoring mode, which can achieve a further simplified and high-throughput detection. The sensing strategy might be extended to the activity detection of other enzymes, thus showing great application potential in bioanalysis and clinical diagnosis.

Abstract
In this work, a label-free electrochemical apta-nanosensor was fabricated on a single gold nanodisk electrode (AuNDE) for thrombin sensing with high sensitivity via a novel signal amplification strategy. This recognition platform was fabricated via self-assembly of helper DNA (HP-DNA), thrombin-binding aptamer (TBA) and gold nanoparticle (AuNP)-DNA complexes to form a sandwich structure on the AuNDE surface. A novel signal amplification strategy via designed AuNP-DNA complexes was introduced using Ru(NH3)63+ as the signal reporter based on the electrostatic interaction. In the presence of thrombin, the strong interaction between the TBA and target led to the dissociation of sandwich DNA complexes from the AuNDE, which resulted in the reduction current of Ru(NH3)63+. This proposed sensing platform showed a wide detection range of 0.1 pM-5 nM and a low detection limit of 0.02 pM. Considering the small overall dimensions and high sensitivity, this nanosensor can be potentially applied for bioanalysis in living biosystems.

Abstract
A rapid and ultrasensitive method is described for the detection of Staphylococcal enterotoxin B (SEB). It is based on the formation of the flower like nucleic acid nanostructure by integrating (a) target-induced triggering of DNA release with (b) signal amplification by a hybridization chain reaction (HCR). Firstly, partially complementary pairing of aptamer and trigger DNA forms a duplex structure. The capture DNA (cpDNA) is then placed on the surface of gold electrode through gold-thiol chemistry. In the presence of SEB, the aptamer-target conjugate is compelled to form. This causes the release of trigger DNA owing to a strong competition between aptamer and SEB. Then, the trigger DNA is subsequently hybridized with the partial complementary sequences of the cpDNA to trigger HCR with three auxiliary DNA sequences (referred to as MB1, MB2, MB3). Finally, the flower like nucleic acid nanostructures are formed and allow numerous hexaammineruthenium(iii) chloride ([Ru(NH3)6]3+, RuHex) to be absorbed on the DNA by electrostatic interaction, and thus amplify electrochemical signal. Under optimal conditions, the chronocoulometry charge difference increases linearly with the logarithm of the SEB concentrations in the range from 5 pg mL−1 to 100 ng mL−1 with a detection limit as low as 3 pg mL−1 (S/N = 3). A rapid and ultrasensitive method is described for the detection of Staphylococcal enterotoxin B (SEB).![]()

Abstract
DNA methylation is one of the significant epigenetic modifications involved in mammalian development as well as in the initiation and progression of various diseases like cancer. Over the past few decades, an enormous amount of research has been carried out for the quantification of DNA methylation in the mammalian genome. Earlier, most of these methodologies used bisulfite treatment. However, the low conversion, false reading, longer assay time and complex chemical reaction are the common limitations of this method that hinder their application in routine clinical screening. Thus, as an alternative to bisulfite conversion-based DNA methylation detection, numerous bisulfite-free methods have been proposed. In this regard, electrochemical biosensors have gained much attention in recent years for being highly sensitive yet cost-effective, portable, and simple to operate. On the other hand, biosensors with optical readouts enable direct real time detection of biological molecules and are easily adaptable to multiplexing. Incorporation of electrochemical and optical readouts into bisulfite free DNA methylation analysis is paving the way for the translation of this important biomarker into standard patient care. In this review, we provide a critical overview of recent advances in the development of electrochemical and optical readout based bisulfite free DNA methylation assays.

Abstract
DNA methyltransferase (MTase) has a crucial role in many biological processes, its abnormal expression level has been regarded as a predictive cancer biomarker. Herein, a sensitive fluorescence method based on thermosensitive poly (N-isopr-opylacrylamide) was developed to assay of M.SssI activity. When the M.SssI was introduced, dsDNA was methylated at palindromic sequence 5'-CmCGG-3' and became resistant to cleavage by the endonuclease HpaII. Therefore, a biotin modified ssDNA and a FAM modified ssDNA were designed including the recognized sites for both methyltransferase M.SssI and endonuclease HpaII. By SA-biotin intereaction, the DNA was conjugated to thermosensitive poly (N-isopropylacrylamide) modified by SA, the methylated substrate fluorescence was increased with the concentration of M.SssI increasing. The proposed method has a low detection limit of 0.18 U/mL. This simple method can be a useful tool to apply in diagnosis and biomedical research, which was successfully investigated in the serum sample.

Abstract
Early diagnosis of HIV biomarkers or genes is the key to reducing acquired immunodeficiency syndrome (AIDS) mortality. In our work, we developed a novel polymerase chain reaction-dynamic light scattering (PCR-DLS) assay for one-step sensitive detection of HIV DNA based on the average-diameter change of gold nanoparticles (AuNPs). This is the first PCR assay that makes use of the DLS technique as a signal read-out, with the particle size measured by DLS increasing with the concentration of target DNA. With the help of the AuNP probes, this PCR-DLS assay can effectively improve the specificity of PCR reactions, which can greatly increase the detection sensitivity, with a detection limit of 1.8 aM (S/N = 3). In addition, the proposed strategy was successfully used to analyze target DNA in human serum samples, indicating that the PCR-DLS assay has a promising potential application for rapid and early clinical diagnosis of HIV infection.

Abstract
DNA methyltransferase (MTase) aberrant expression has a close relationship to tumorigenesis. DNA MTase activity detection is of great importance to its biomedical research and theranostics study. Here, multiple sealed primers-mediated rolling circle amplification (RCA) strategy is developed for sensitively and specifically detecting DNA MTase activity. The DNA probe has a folded, double-loop structure that seals multiple primers. First, in the presence of DNA MTase, the DNA probe is methylated, which then gets cleaved by the restriction endonuclease and breaks into multiple DNA oligonucleotide fragments. Second, each DNA oligonucleotide fragment acts as an independent primer for triggering RCA reaction respectively, producing long DNA strands that contain several interval G-quadruplexes. Finally, copious of G-quadruplexes are obtained, which bind N-methylmesoporphyrin IX (NMM) to generate significantly enhanced fluorescence. When DNA MTase is absent or inactive, the DNA probe is stable and cannot release the primers for RCA reaction. In the proposed strategy, the action of DNA MTase on one DNA probe is converted to the multiple amplifications triggered by multiple released primers. The detection limit for Dam MTase is down to 0.0085 U/mL, and the target MTase can be well discriminated from its MTases analogues. The method is utilized in screening of Dam MTase inhibitors and analyzing of spiked Dam MTase in biological samples. The results suggest that the strategy may provide a promising tool for DNA MTase activity detection in biomedical research and cancer theranostics.

Abstract
In this work, a competitive and label-free electrochemical platform was performed for the ultrasensitive cytosensing of liver cancer cells based on DNA nanotetrahedron (NTH) structure and rolling circle amplification (RCA) directed DNAzyme strategy. The multifunctional nanoprobes were fabricated through a DNA primer probe, carboxyfluorescein (FAM) functionalized TLS11a aptamer and horseradish peroxidase (HRP) immobilized on the surfaces of the platinum nanoparticles (PtNPs). Then the NTH-based complementary DNA (cDNA) probe, complementary to the TLS11a aptamer, was attached on a disposable screen-printed gold electrode (SPGE) for increasing the reactivity and accessibility with the prepared nanoprobes. Due to the primer probe and the circular probe with G-quadruplex sequences for RCA, it can lead to the formation of numerous G-quadruplex/hemin DNAzyme, thus generating a remarkable electrochemical response. When the target cells were present, the nanoprobes were released from the SPGE due to the specific recognition of TLS11a aptamers for HepG2 cells, resulting in the electrochemical signal changes. The cytosensor was ultrasensitive for HepG2 tumor cell detection with a detection limit of 3 cell per mL. Furthermore, this strategy was also demonstrated to be applicable for cancer cell imaging. In summary, this electrochemical cytosensor holds great potential for circulating tumor cell detection in the early cancer diagnose.

Abstract
Specific and sensitive detection of DNA MTase activity can be achieved by a single-ribonucleotide repair-mediated ligation-dependent cycling signal amplification approach.
DNA methylation is a predominant epigenetic modification that plays crucial roles in various cellular processes. DNA methyltransferase (MTase) is responsible for DNA methylation, and its dysregulation may induce aberrant methylation patterns that are closely related to cancers. Conventional methods for DNA MTase assay are usually cumbersome and laborious with poor sensitivity. Alternatively, some signal amplification strategies are employed to improve the sensitivity, but they suffer from poor specificity and consequently limited sensitivity due to the nonspecific amplification. Herein, we develop for the first time a new fluorescence method to specifically and sensitively detect DNA MTase activity on the basis of single-ribonucleotide repair-mediated ligation-dependent cycling signal amplification. In the presence of DNA MTase, the hairpin substrate is methylated and cleaved by endonuclease Dpn I, releasing a 24-nt cleavage product. The 24-nt cleavage product may function as a primer and adjacently hybridize with the ligation probes (LP1 and LP2) to form the template (LP1–LP2) for strand displacement amplification (SDA), initiating the single-ribonucleotide repair-mediated cyclic ligation-dependent SDA to produce a large number of reporter probes. The reporter probe can subsequently hybridize with the signal probe that is modified with FAM and BHQ1 to form a stable double-stranded DNA (dsDNA) duplex with a ribonucleotide mismatch. Ribonuclease HII (RNase HII) can excise the single ribonucleotide, resulting in the cyclic cleavage of signal probes and the generation of an enhanced fluorescence signal. Taking advantage of the high specificity of RNase HII-catalyzed single-ribonucleotide excision and the high amplification efficiency of cyclic ligation-dependent SDA, this assay exhibits the highest sensitivity reported so far with a detection limit of 4.8 × 10–6 U mL–1 and a large dynamic range of 5 orders of magnitude. Moreover, this method can be used for the discrimination of Dam MTase from other DNA MTases, the accurate quantification of Dam MTase activity in E. coli cells, and the screening of Dam MTase inhibitors, providing a new paradigm for biomedical research and clinical diagnosis.

Abstract
Sensitive and specific detection of tumor exosomes is of great significance for early cancer diagnosis. In this paper, we report an aptamer strategy for exosome detection based on aptamer recognition-induced multi-DNA release and cyclic enzymatic amplification. First, we use aptamer-magnetic bead bioconjugates to capture tumor exosomes derived from LNCaP cells, leading to the release of three kinds of messenger DNAs (mDNAs). After magnetic separation, the released mDNAs hybridized with the probe DNAs immobilized on a gold electrode. Electroactive Ru(NH3)63+ was used as the signal reporter because of its electrostatic attraction to DNA. Subsequent Exo III cyclic digestion caused the electrochemical signal to "turn off". Because the electrochemical signal reflects the concentration of Ru(NH3)63+ and the concentration of Ru(NH3)63+ is correlated with the mDNA concentration, which is correlated with the exosome concentration, the tumor exosomes can be detected by examining the decrease in the peak current of Ru(NH3)63+. In this paper, the signal was amplified by the numerous mDNAs released from the magnetic bead and the Exo III-assisted mDNA recycling. Under the optimal conditions, a detection limit down to 70 particles/μL was achieved, which is lower than the LODs of most currently available methods. Furthermore, this assay can be used to detect tumor exosomes in complex biological samples, demonstrating potential application in real sample diagnosis.

Abstract
Background DNA methyltransferase 1 (DNMT1), a dominant enzyme responsible for the transfer of a methyl group from the universal methyl donor to the 5-position of cytosine residues in DNA, is essential for mammalian development and closely related to cancer and a variety of age-related chronic diseases. DNMT1 has become a useful biomarker in early disease diagnosis and a potential therapeutic target in cancer therapy and drug development. However, till now, most of the studies on DNA methyltransferase (MTase) detection have focused on the prokaryote MTase and its activity. Methods A magnetic fluorescence-linked immunosorbent assay (FLISA) using CdSe/ZnS quantum dots as fluorescent probes was proposed for the rapid and sensitive detection of the DNMT1 level in this study. Key factors that affect the precision and accuracy of the determination of DNMT1 were optimized. Results Under the optimal conditions, the limit of detection was 0.1 ng/mL, the linear range was 0.1-1,500 ng/mL, the recovery was 91.67%-106.50%, and the relative standard deviations of intra- and inter-assays were respectively 5.45%-11.29% and 7.03%-11.25%. The cross-reactivity rates with DNA methyltransferases 3a and 3b were only 4.0% and 9.4%, respectively. Furthermore, FLISA was successfully used to detect the levels of DNMT1 in human serum samples, and compared with commercial enzyme-linked immunosorbent assay (ELISA) kits. The results revealed that there was a good correlation between FLISA and commercial ELISA kits (correlation coefficient r=0.866, p=0.001). The linear scope of FLISA was broader than ELISA, and the measurement time was much shorter than ELISA kits. Conclusion These indicated that the proposed FLISA method was sensitive and high throughput and can quickly screen the level of DNMT1 in serum samples.

Abstract
Human DNA methyltransferase (MTase) activity expression patterns and inhibition response are linked to related cancer initiation, progression, and therapeutic responses. Sensitive and accurate human MTase activity assay in cancer cells, especially at the single-cell level, is essential for biological study, clinical diagnosis, and therapy. Here, we developed an ultrasensitive and accurate DNA (cytosine-5)-methyltransferase 1 (Dnmt1) activity assay at the single-cell level based on a single integrated magnetic microprobe of functionalized double-stranded DNA (dsDNA) anchored to a single magnetic microbead surface. Functionalized dsDNA is designed with a hemimethylated DNA site for Dnmt1 recognition and a single-stranded tail to trigger in situ rolling circle amplification (RCA). Under the action of Dnmt1, hemimethylated dsDNA could be recognized and catalyzed to fully methylated dsDNA, which would protect them from the cleavage of BssHII. However, the dsDNA without full methylation would be cut by BssHII, making single-stranded tail separated from the single integrated microprobe. Subsequently, full methylation-protected in situ RCA could be performed, and multiple signal probes were hybridized to the single integrated microprobe for amplified signal accumulation. Finally, Dnmt1 activity could be evaluated by reading the fluorescence of the single integrated microprobe. Meanwhile, to minimize matrix interferences, magnetic separation was performed in the process. In this strategy, the single integrated magnetic microprobe was provided with integrated capacities of target recognition, signal amplification, signal accumulation, and matrix isolation. Therefore, an ultralow detection limit of 0.007 U/mL Dnmt1 was obtained, and accurate Dnmt1 activity assays in multiple cell lysates at the single-cell level were achieved. Furthermore, the inhibition effect of RG108 was evaluated conveniently. These results indicate that the single integrated magnetic microprobe-based strategy is an excellent candidate for sensitive monitoring of Dnmt1 activity and screening of anticancer drugs.

Abstract
In this paper, we reported a sensitive and selective electrochemical method for quantify DNA methylation, analyzing DNA MTase activity and screening of MTase inhibitor based on silver nanoparticles (Ag NPs) decorated carbon nanocubes (CNCs) as signal tag. The Ag NPs/CNCs was prepared by in situ growth of nanosilver on carboxylated CNCs and used as a tracing tag to label antibody. The sensor was prepared by immobilizing the double DNA helix structure on the surface of gold electrode. When DNA MTase was introduced, the probe was methylated. Successively, anti-5-methylcytosine antibody labeled Ag NPs/CNCs was specifically conjugated on the CpG methylation site. The electrochemical stripping signal of the Ag NPs was used to monitor the activity of MTase. The electrochemical signal has a linear relationship with M.SssI activities ranging from 0.05 to 120U/mL with a detection limit of 0.03U/mL. In addition, we also demonstrated the method could be used for rapid evaluation and screening of the inhibitors of MTase. The newly designed strategy avoid the requirement of deoxygenation for electrochemical assay, and thus provide a promising potential in clinical application.
