Abstract
The advantages of rapid amplification of nucleic acid without a template based on terminal deoxyribonucleotidyl transferase (TdT) have been widely used in the field of biosensors. However, the catalytic efficiency of TdT is affected by extension conditions. The sensitivity of TdT- mediated biosensors can be improved only under appropriate conditions. Therefore, in this review, we provide a comprehensive overview of TdT extension characteristics and its applications in biosensors. We focus on the relationship between TdT extension conditions and extension efficiency. Furthermore, the construction strategy of TdT-mediated biosensors according to five different recognition types and their applications in targets are discussed and, finally, several current challenges and prospects in the field are taken into consideration.

[PMID: 38876521 DOI: 10.1016/j.aca.2024.342799] [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: 03/08/2024] [Revised: 05/05/2024] [Accepted: 05/29/2024] [Indexed: 06/16/2024]
Abstract
BACKGROUND As a core enzyme in the base excision repair system, uracil DNA glycosylase (UDG) is indispensable in maintaining genomic integrity and normal cell cycles. Its abnormal activity intervenes in cancers and neurodegerative diseases. Previous UDG assays based on isothermal amplification and Clustered Regularly Interspaced Short Palindromic Repeats/Cas (CRISPR/Cas) system were fine in sensitivity, but exposed to complications in assay flow, time, and probe design. After isothermal amplification, a CRISPR/Cas reagent should be separately added with extra manual steps and its guide RNA (gRNA) should be designed, considering the presence of protospacer adjacent motif (PAM) site. RESULTS We herein describe a UDG-REtarded CRISPR Amplification assay, termed 'URECA'. In URECA, isothermal nucleic acid (NA) amplification and CRISPR/Cas12a system were tightly combined to constitute a one-pot, isothermal CRISPR amplification system. Isothermal NA amplification for a UDG substrate (US) with uracil (U) bases was designed to activate and boost CRISPR/Cas12a reaction. Such scheme enabled us to envision that UDG would halt the isothermal CRISPR amplification reaction by excising U bases and messing up the US. Based on this principle, the assay detected the UDG activity down to 9.17 x 10-4 U/mL in 50 min. With URECA, we fulfilled the recovery test of UDG activities in plasma and urine with high precision and reproducibility and reliably determined UDG activities in cell extracts. Also, we verified its capability to screen candidate UDG inhibitors, showing its potentials in practical application as well as drug discovery. SIGNIFICANCE URECA offers further merits: i) the assay is seamless. Following target recognition, the reactions proceed in one-step without any intervening steps, ii) probe design is simple. Unlike the conventional CRISPR/Cas12a-based assays, URECA does not consider the PAM site in probe design as Cas12a activation relies on instantaneous gRNA binding to single-stranded DNA strands. By rationally designing an enzyme substrate probe to be specific to other enzymes, while keeping a role as a template for isothermal CRISPR amplification, the detection principle of URECA will be expanded to devise biosensors for various enzymes of biological, clinical significance.

Abstract
DNA glycosylases are a group of enzymes that play a crucial role in the DNA repair process by recognizing and removing damaged or incorrect bases from DNA molecules, which maintains the integrity of the genetic information. The abnormal expression of uracil-DNA glycosylase (UDG), one of significant DNA glycosylases in the base-excision repair pathway, is linked to numerous diseases. Here, we proposed a simple UDG activity detection method based on toehold region triggered CRISPR/Cas12a trans-cleavage. The toehold region on hairpin DNA probe (HP) produced by UDG could induce the trans-cleavage of ssDNA with fluorophore and quencher, generating an obvious fluorescence signal. This protospacer adjacent motif (PAM)-free approach achieves remarkable sensitivity and specificity in detecting UDG, with a detection limit as low as 0.000368 U mL-1. Moreover, this method is able to screen inhibitors and measure UDG in complex biological samples. These advantages render it highly promising for applications in clinical diagnosis and drug discovery.

Abstract
Nucleic acids are essential biomarkers in molecular diagnostics. The CRISPR/Cas system has been widely used for nucleic acid detection. Moreover, canonical CRISPR/Cas12a based biosensors can specifically recognize and cleave target DNA, as well as single-strand DNA serving as reporter probe, which have become a super star in recent years in the field of nucleic acid detection due to its high specificity, universal programmability and simple operation. However, canonical CRISPR/Cas12a based biosensors are hard to meet the requirements of higher sensitivity, higher specificity, higher efficiency, larger target scope, easier operation, multiplexing, low cost and diversified signal reading. Then, advanced non-canonical CRISPR/Cas12a based biosensors emerge. In this review, applications of non-canonical CRISPR/Cas12a-based biosensors in nucleic acid detection are summarized. And the principles, peculiarities, performances and perspectives of these non-canonical CRISPR/Cas12a based biosensors are also discussed.

Abstract
Alternaria is a plant pathogen that spreads globally and is prone to causing citrus brown spot disease and metabolizing mycotoxins, thus seriously hindering the development of this economic crop industry. Herein, a "label-free" and "turn on" visual fluorescent assay for citrus Alternaria based on CRISPR-Cas12a and rolling circle amplification (RCA) was described. Using ssDNA complementary to RCA primer as a trans-cleavage substrate for CRISPR-Cas12a, the two systems of CRISPR-Cas12a and RCA-amplified G-quadruplex were skillfully integrated. By using a portable light source for excitation, the positive sample produced obvious red fluorescence, while the negative sample remained almost colorless, making them easy to differentiate with the naked eye. In addition, the specificity was demonstrated by distinguishing Alternaria from other citrus disease related pathogens. Moreover, the practicality was verified by analyzing cultured Alternaria and Alternaria in actual citrus leaf and fruit samples. Therefore, this method may contribute to the on-site diagnosis of Alternaria.

Abstract
As an essential protein in DNA repair, apurinic/apyrimidinic endonuclease 1 (APE1) plays multiple critical functions in maintaining homeostasis, making it a significant biomarker and therapeutic target for many disorders. Here, we describe a simple method to detect APE1 based on the Releasing-Extension-Signal amplification Test (REST) strategy that leverages the dsDNA as the activator to fully unlock the trans-cleavage activity of CRISPR/Cas12a. This assay provides a rapid and specific APE1 detection with a detection limit down to 1.05 × 10-5 U/mL. We also combined this method with an automated pipetting platform and a microplate reader for high-throughput screening of potential inhibitors of APE1. Besides, by changing the modification on the probe, the REST strategy was easily repurposed to detect various DNA glycosylases. Taken together, the simplicity and robustness of the method offer a new choice for APE1 detection and inhibitor screening, showing great potential in practical use. Furthermore, the REST strategy devised in this study provides a new example of applying CRISPR/Cas12a signal amplifier to non-nucleic acid biosensing and inhibitor screening, which broadens the CRISPR-Dx toolbox.

Abstract
Nucleic acid aptamer-based nanomicelles have great potential for nanomedicine and nanotechnology applications. However, amphiphilic aptamer micelles are known to be inherently unstable upon interaction with cell membranes in the physiological environment, thus potentially compromising their specific targeting against cancer cells. This flaw is addressed in the present work which reports a superstable micellar nanodelivery system as an amphiphilic copolymer self-assembled micelle composed of nucleic acid aptamer and polyvalent hydrophobic poly(maleic anhydride-alt-1-octadecene) (C18PMH). Using Ce6 as a drug model, these C18-aptamer micelles exhibit efficient tumor-targeting and -binding ability, facilitating the entry of Ce6 into targeted cells for photodynamic therapy. In addition, they can be loaded with other hydrophobic drugs and still demonstrate favorable therapeutic effects. As such, these C18-aptamer micelles can serve as a universal platform for loading multiple drugs, providing a safer and more effective solution for treating cancer.

Abstract
The trans-cleavage activity of CRISPR/Cas12a has been widely used in biosensing. However, many CRISPR/Cas12a-based biosensors, especially those that work in "on-off-on" mode, usually suffer from high background and thus impossible intracellular application. Herein, this problem is efficiently overcome by elaborately designing the activator strand (AS) of CRISPR/Cas12a using the "RESET" effect found by our group. The activation ability of the as-designed AS to CRISPR/Cas12a can be easily inhibited, thus assuring a low background for subsequent biosensing applications, which not only benefits the detection sensitivity improvement of CRISPR/Cas12a-based biosensors but also promotes their applications in live cells as well as makes it possible to design high-performance biosensors with greatly improved flexibility, thus achieving the analysis of a wide range of targets. As examples, by using different strategies such as strand displacement, strand cleavage, and aptamer-substrate interaction to reactivate the inhibited enzyme activity, several CRISPR/Cas12a-based biosensing systems are developed for the sensitive and specific detection of different targets, including nucleic acid (miR-21), biological small molecules (ATP), and enzymes (hOGG1), giving the detection limits of 0.96 pM, 8.6 μM, and 8.3 × 10-5 U/mL, respectively. Thanks to the low background, these biosensors are demonstrated to work well for the accurate imaging analysis of different biomolecules in live cells. Moreover, we also demonstrate that these sensing systems can be easily combined with lateral flow assay (LFA), thus holding great potential in point-of-care testing, especially in poorly equipped or nonlaboratory environments.

Abstract
With the increasing acreage of genetically modified crops worldwide, rapid and efficient detection technologies have become very important for the regulation and screening of GM organisms. We constructed a method based on loop-mediated isothermal amplification (LAMP), CRISPR-Cas12a and lateral flow assay (LAMP-CRISPR-Cas12a-LFA). It is an intuitive, sensitive and specific fluorescence detection and test strip system to detect CP4-EPSPS and Cry1Ab/Ac genes in field screening. The LAMP-CRISPR-Cas12a-LFA method has a limit of detection (LOD) of 100 copies based on lateral flow test strips after optimization of the conditions with screened specific primers, and the entire detection process can be completed within 1 h at 61 °C. The system was used to evaluate field test samples and showed high reproducibility after testing products containing CP4-EPSPS and Cry1Ab/Ac genes, and both were detectable. The LAMP-CRISPR-Cas12a-LFA method established in this paper functions as a rapid field detection method. It requires only one portable thermostatic instrument, which renders it compatible with the rapid detection of field samples and useable at experimental workstations, in law enforcement field work, and in local inspection and quarantine departments.

Abstract
CRISPR/Cas systems have found widespread applications in gene editing due to their high accuracy, high programmability, ease of use, and affordability. Benefiting from the cleavage properties (trans- or cis-) of Cas enzymes, the scope of CRISPR/Cas systems has expanded beyond gene editing and they have been utilized in various fields, particularly in live-cell imaging and bioanalysis. In this review, we summarize some fundamental working mechanisms and concepts of the CRISPR/Cas systems, describe the recent advances and design principles of CRISPR/Cas mediated techniques employed in live-cell imaging and bioanalysis, highlight the main applications in the imaging and biosensing of a wide range of molecular targets, and discuss the challenges and prospects of CRISPR/Cas systems in live-cell imaging and biosensing. By illustrating the imaging and bio-sensing processes, we hope this review will guide the best use of the CRISPR/Cas in imaging and quantifying biological and clinical elements and inspire new ideas for better tool design in live-cell imaging and bioanalysis.

A novel biosensor based on tetrahedral DNA nanostructure and terminal deoxynucleotidyl transferase-assisted amplification strategy for fluorescence analysis of uracil-DNA glycosylase activity. Anal Chim Acta 2023; 1271:341432. [PMID: 37328254 DOI: 10.1016/j.aca.2023.341432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 05/24/2023] [Accepted: 05/25/2023] [Indexed: 06/18/2023]
Abstract
Tetrahedral DNA nanostructure (TDN), as a classical bionanomaterial, which not only has excellent structural stability and rigidity, but also possesses high programmability due to strict base-pairs complementation, is widely used in various biosensing and bioanalysis fields. In this study, we first constructed a novel biosensor based on Uracil DNA glycosylase (UDG) -triggered collapse of TDN and terminal deoxynucleotidyl transferase (TDT)-induced insertion of copper nanoparticles (CuNPs) for fluorescence and visual analysis of UDG activity. In the presence of the target enzyme UDG, the uracil base modified on the TDN were specifically identified and removed to produce an abasic site (AP site). Endonuclease IV (Endo.IV) could cleave the AP site, making the TDN collapse and generating 3'-hydroxy (3'-OH), which were then elongated under the assistance of TDT to produce poly (T) sequences. Finally, Copper (II) sulfate (Cu2+) and l-Ascorbic acid (AA) were added to form CuNPs using poly (T) sequences as templates (T-CuNPs), resulting in a strong fluorescence signal. This method exhibited good selectivity and high sensitivity with a detection limit of 8.6 × 10-5 U/mL. Moreover, the strategy has been successfully applied to the screening of UDG inhibitors and the detection of UDG activity in complex cell lysates, which means that it has promising applications in clinical diagnosis and biomedical research.

Abstract
The pandemic of COVID-19 creates an imperative need for sensitive and portable detection of SARS-CoV-2. We devised a SERS-read, CRISPR/Cas-powered nanobioassay, termed as OVER-SARS-CoV-2 (One-Vessel Enhanced RNA test on SARS-CoV-2), which enabled supersensitive, ultrafast, accurate and portable detection of SARS-CoV-2 in a single vessel in an amplification-free and anti-interference manner. The SERS nanoprobes were constructed by conjugating gold nanoparticles with Raman reporting molecular and single-stranded DNA (ssDNA) probes, whose aggregation-to-dispersion changes can be finely tuned by target-activated Cas12a though trans-cleavage of linker ssDNA. As such, the nucleic acid signals could be dexterously converted and amplified to SERS signals. By customizing an ingenious vessel, the steps of RNA reverse transcription, Cas12a trans-cleavage and SERS nanoprobes crosslinking can be integrated into a single and disposal vessel. It was proved that our proposed nanobioassay was able to detect SARS-CoV-2 as low as 200 copies/mL without any pre-amplification within 45 min. In addition, the proposed nanobioassay was confirmed by clinical swab samples and challenged for SARS-CoV-2 detection in simulated complex environmental and food samples. This work enriches the arsenal of CRISPR-based diagnostics (CRISPR-Dx) and provides a novel and robust platform for SARS-CoV-2 decentralized detection, which can be put into practice in the near future.

Abstract
Uracil-DNA glycosylase (UDG) is pivotal in maintaining genome integrity and aberrant expressed UDG is highly relevant to numerous diseases. Sensitive and accurate detecting UDG is critically significant for early clinical diagnosis. In this research, we demonstrated a sensitive UDG fluorescent assay based on rolling circle transcription (RCT)/CRISPR/Cas12a-assisted bicyclic cascade amplification strategy. Target UDG catalyzed to remove uracil base of DNA dumbbell-shape substrate probe (SubUDG) to produce an apurinic/apyrimidinic (AP) site, at which SubUDG was cleaved by apurinic/apyrimidinic endonuclease (APE1) subsequently. The exposed 5'-PO4 was ligated with the free 3'-OH terminus to form an enclosed DNA dumbbell-shape substrate probe (E-SubUDG). E-SubUDG functioned as a template can actuate T7 RNA polymerase-mediated RCT signal amplification, generating multitudes of crRNA repeats. The resultant Cas12a/crRNA/activator ternary complex activated the activity of Cas12a, causing a significantly enhanced fluorescence output. In this bicyclic cascade strategy, target UDG was amplified via RCT and CRISPR/Cas12a, and the whole reaction was completed without complex procedures. This method enabled sensitive and specific monitor UDG down to 0.0005 U/mL, screen corresponding inhibitors, and analyze endogenous UDG in A549 cells at single-cell level. Importantly, this assay can be extended to analyze other DNA glycosylase (hAAG and Fpg) by altering the recognition site in DNA substrates probe rationally, thereby offering a potent tool for DNA glycosylase-associated clinical diagnosis and biomedical research.

Abstract
Nuclease, such as RNase H and DNase I, plays key roles in plenty of cellular processes and could be potential therapeutic target for drug development. It is necessary to establish rapid and simple-to-use methods to detect nuclease activity. Herein, we develop a Cas12a-based fluorescence assay without any nucleic acid amplification steps for ultrasensitive detection of RNase H or DNase I activity. By our design, the pre-assembled crRNA/ssDNA duplex triggered the cleavage of fluorescent probes in the presence of Cas12a enzymes. However, the crRNA/ssDNA duplex was selectively digested with the addition of RNase H or DNase I, which leaded to fluorescence intensity changes. Under optimized conditions, the method exhibited good analytical performance, achieving a limit of detection (LOD) as low as 0.0082 U/mL for RNase H and 0.13 U/mL for DNase I, respectively. The method was feasible for analysis of RNase H in human serum and cell lysates, as well as for screening of enzyme inhibitors. Moreover, it can be adopted to image RNase H activity in living cells. Together, this study provides a facile platform for nuclease detection and could be expanded for other biomedical research and clinical diagnostics.

Abstract
An isothermal, one-pot toolbox (called OPT-Cas) based on CRISPR-Cas12a collateral cleavage capability is proposed for highly sensitive and selective determination of terminal deoxynucleotidyl transferase (TdT) activity. Oligonucleotide primers with 3'-hydroxyl (OH) terminal were randomly introduced for TdT-induced elongation. In the presence of TdT, dTTP nucleotides polymerized at the 3' terminals of the primers to generate abundant polyT-tails, which function as triggers for the synchronous activation of Cas12a proteins. Finally, the activated Cas12a trans-cleaved FAM and BHQ1 dual-labeled single-stranded DNA (ssDNA-FQ) reporters, producing significantly amplified fluorescence signals. This one-pot assay, that is primer, crRNA, Cas12a protein and ssDNA-FQ reporter are all in one tube, allows simple but high-sensitive quantification of TdT activity with a low detection limit of 6.16 × 10-5 U μL-1 in the concentration scope from 1 × 10-4 U μL-1 to 1 × 10-1 U μL-1, and achieves extraordinary selectivity with other interfering proteins. Furthermore, the OPT-Cas was successfully used to detect TdT in complex matrices and accurate determination of TdT activity in acute lymphoblastic leukemia cells, which might be a reliable technique platform for the diagnosis of TdT-related diseases and biomedical research applications.

Abstract
Pathogenic variants of Burkholderia gladioli pose a serious threat to human health and food safety, but there is a lack of rapid and sensitive field detection methods for Burkholderia gladioli. In this study, the CRISPR/Cas12a system combined with recombinant enzyme polymerase amplification (RPA) was used to detect Burkholderia gladioli in food. The optimized RPA-CRISPR/Cas12a assay was able to specifically and stably detect Burkholderia gladioli at a constant 37 °C without the assistance of large equipment. The detection limit of the method was evaluated at two aspects, the genomic DNA (gDNA) level and bacterial quantity, of which there were 10-3 ng/μL and 101 CFU/mL, respectively. Three kinds of real food samples were tested. The detection limit for rice noodles, fresh white noodles, and glutinous rice flour samples was 101 CFU/mL, 102 CFU/mL, and 102 CFU/mL, respectively, without any enrichment steps. The whole detection process, including sample pretreatment and DNA extraction, did not exceed one hour. Compared with the qPCR method, the established RPA-CRISPR /Cas12a method was simpler and even more sensitive. Using this method, a visual detection of Burkholderia gladioli that is suitable for field detection can be achieved quickly and easily.

Ultra-sensitive biosensor based on CRISPR-Cas12a and Endo IV coupled DNA hybridization reaction for uracil DNA glycosylase detection and intracellular imaging. Biosens Bioelectron 2023; 226:115118.

Abstract
As an essential biomarker associated with various diseases, Uracil-DNA Glycosylase (UDG) detection is vital for disease diagnosis, treatment selection, and prognosis assessment. In recent years, the signal amplification effect of the CRISPR-Cas12a trans-cleaved single-stranded DNA probe has provided an available strategy for constructing highly sensitive biosensors. However, its superior trans-cleavage activity has become a "double-edged sword" for building biosensors that can amplify the target signal while also amplifying the leakage signal, causing out of control. Therefore, the construction of structurally simple, extremely low-background, highly sensitive CRISPR-Cas12a-based biosensors is an urgent bottleneck problem in the field. Here, we applied CRISPR-Cas12a with a DNA hybridization reaction to develop a simple, rapid, low background, and highly sensitive method for UDG activity detection. It has no PAM restriction and the detection limit is as low as 2.5 × 10-6 U/mL. As far as we know, this method is one of the most sensitive methods for UDG detection. We also used this system to analyze UDG activity in tumor cells (LOD: 1 cell/uL) and to evaluate the ability to screen for UDG inhibitors. Furthermore, we verified the possibility of intracellular UDG activity imaging by transfecting the biosensors to the cells. We believe this novel sensor has good clinical application prospects and will effectively broaden the application space of CRISPR-Cas12a.

Abstract
The CRISPR (Clustered Regularly Spaced Short Palindromic Repeats) system was first discovered in prokaryotes as a unique immune mechanism to clear foreign nucleic acids. It has been rapidly and extensively used in basic and applied research owing to its strong ability of gene editing, regulation and detection in eukaryotes. Hererin in this article, we reviewed the biology, mechanisms and relevance of CRISPR-Cas technology and its applications in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnosis. CRISPR-Cas nucleic acid detection tools include CRISPR-Cas9, CRISPR-Cas12, CRISPR-Cas13, CRISPR-Cas14, CRISPR nucleic acid amplification detection technology, and CRISPR colorimetric readout detection system. The above CRISPR technologies have been applied to the nucleic acid detection, including SARS-CoV-2 detection. Common nucleic acid detection based on CRISPR derivation technology include SHERLOCK, DETECTR, and STOPCovid. CRISPR-Cas biosensing technology has been widely applied to point-of-care testing (POCT) by targeting recognition of both DNA molecules and RNA Molecules.

Abstract
Cadmium ion (Cd(II)) is a pernicious environmental pollutant that has been shown to contaminate agricultural lands, accumulate through the food chain, and seriously threaten human health. At present, Cd(II) monitoring is dependent on centralized instruments, necessitating the development of rapid and on-site detection platforms. Against this backdrop, the present study reports on the development of a fluorometric aptasensor designed to target Cd(II), which is achieved through the integration of strand displacement amplification (SDA) and CRISPR/Cas12a. In the absence of Cd(II), the aptamer initiates SDA, resulting in the generation of a profusion of ssDNA that activates Cas12a, leading to a substantial increase in fluorescence output. Conversely, the presence of Cd(II) curtails the SDA efficiency, culminating in a significant reduction in fluorescence output. The proposed approach has been demonstrated to enable the selective detection of Cd(II) at concentrations of 60 pM, with the performance of the aptasensor validated in real water and rice samples. The proposed platform based on aptamer-target interaction holds immense promise as a signal-amplified and precise method for the detection of Cd(II) and has the potential to transform current hazard detection practices in food samples.

Abstract
Multiple circulating non-coding RNAs (ncRNAs) in serum may serve as vital biomarkers for use in diagnosing early-stage colorectal cancer (CRC). Herein, a universal platform for one-pot detection of CRC-related ncRNAs was developed based on branched rolling circle amplification and CRISPR-Cas12a (BRCACas). For the implementation of the method, primers incorporating ncRNA sequences of circulating CRC-associated RNAs (piRNA or miRNA) were designed that could specifically hybridize with circular probes to initiate the BRCA process. Thereafter, the generation of dendritic DNA products triggered Cas12a trans-cleavage activity to elicit a fluorescent signal. The proposed method, combining high BRCA reaction efficiency with powerful Cas12a trans-cleavage activity, provided greatly enhanced detection sensitivity, as reflected by limits of detection (LODs) for model piRNA (piR-54265) and model miRNA (miR21) of 0.76 fM and 0.87 fM, respectively. Notably, the proposed BRCACas platform, assaying two different types of CRC-associated ncRNAs in patient samples, produced consistent results with the conventional reverse transcription-quantitative PCR (RT-qPCR) method. Therefore, the one-pot, isothermal, and specific BRCACas platform provided excellent performance, thus demonstrating its promise as a rapid, adaptable, and practical diagnostic/prognostic cancer screening method.

Abstract
The use of polymerase enzymes in biotechnology has allowed us to gain unprecedented control over the manipulation of DNA, opening up new and exciting applications in areas such as biosensing, polynucleotide synthesis, and DNA storage, aptamer development and DNA-nanotechnology. One of the most intriguing enzymes which has gained prominence in the last decade is terminal deoxynucleotidyl transferase (TdT), which is one of the only polymerase enzymes capable of catalysing the template independent stepwise addition of nucleotides onto an oligonucleotide chain. This unique enzyme has seen a significant increase in a variety of different applications. In this review, we give a comprehensive discussion of the unique properties and applications of TdT as a biotechnology tool, and the application in the enzymatic synthesis of poly/oligonucleotides. Finally, we look at the increasing role of TdT enzyme in biosensing, DNA storage, synthesis of DNA nanostructures and aptamer development, and give a future outlook for this technology.

Abstract
BACKGROUND Helicobacter pylori lives in the human stomach and causes gastric cancer and other gastric diseases. The development of molecular technology has facilitated low-cost, rapid, and high-throughput detection of H. pylori. MATERIALS AND METHODS The combination of isothermal recombinase polymerase amplification (RPA) and CRISPR-Cas12a was used for early diagnosis and monitoring of H. pylori in clinical settings. The UreB genes from 242 H. pylori strains were subjected to cluster analysis, and we designed corresponding RPA primers and screened 2 sets of CRISPR-derived RNAs (crRNAs) for accurate H. pylori recognition. We then performed specificity and sensitivity validation of seven strains using this RPA-CRISPR/Cas12a method. In addition, the cut-off values of this RPA-CRISPR/Cas12a method based on fluorescence values (i.e., RPA-CRISPR/Cas12a-FT) were determined by comparison with quantitative PCR (qPCR), and further experiments comparing different methods were performed using clinical samples. RESULTS We developed a rapid detection system based on the combination of RPA and CRISPR-Cas12a, which was applied to the early diagnosis and monitoring of H. pylori in clinical settings. The RPA-CRISPR/Cas12a system was used to detect the UreB gene. We found that the limit of detection (LOD) for the CRISPR/Cas12a method based on the lateral flow dipstick result (i.e., CRISPR/Cas12a-LFD) was 100 copies, the cut-off value was 1.4; and for CRISPR/Cas12a-FT the LOD was 50 copies. This system was used to assess clinical samples and showed high reproducibility with proof-of-concept sensitivity, and the whole detection process was completed within 40 min. CONCLUSION As a diagnostic method that can detect the UreB gene of H. pylori in gastric tissue samples rapidly, sensitively, visually, and in a high throughput manner, our method provides a new diagnostic option for clinicians. This system is ideal for hospitals or testing sites with limited medical resources.

Abstract
A controllable crRNA self-transcription aided dual-amplified CRISPR-Cas12a strategy (termed CST-Cas12a) was developed for highly sensitive and specific biosensing of flap endonuclease 1 (FEN1), a structure-selective nuclease in eukaryotic cells. In this strategy, a branched DNA probe with a 5' overhanging flap was designed to serve as a hydrolysis substrate of FEN1. The flap cut by FEN1 was annealed with a template probe and functioned as a primer for an extension reaction to produce a double-stranded DNA (dsDNA) containing a T7 promoter and crRNA transcription template. Assisting the T7 RNA polymerase, abundant crRNA was generated and assembled with Cas12a to form a Cas12a/crRNA complex, which can be activated by a dsDNA trigger and unlock the indiscriminate fluorophore-quencher reporter cleavage. The highly efficient dual signal amplification and near-zero background enabled CST-Cas12a with extraordinarily high sensitivity. Under optimized conditions, this method allowed highly sensitive biosensing of FEN1 activity in the range of 1 × 10-5 U μL-1 to 5 × 10-2 U μL-1 with a detection limit of 5.2 × 10-6 U μL-1 and achieved excellent specificity for FEN1 in the presence of other interfering enzymes. The inhibitory capabilities of chemicals on FEN1 were also investigated. Further, the newly established CST-Cas12a strategy was successfully applied to FEN1 biosensing in complex biological samples, which might be a reliable biosensing platform for highly sensitive and specific detection of FEN1 activity in clinical applications.

Abstract
Infectious pathogens cause severe human illnesses and great deaths per year worldwide. Rapid, sensitive, and accurate detection of pathogens is of great importance for preventing infectious diseases caused by pathogens and optimizing medical healthcare systems. Inspired by a microbial defense system (i.e., CRISPR/ CRISPR-associated proteins (Cas) system, an adaptive immune system for protecting microorganisms from being attacked by invading species), a great many new biosensors have been successfully developed and widely applied in the detection of infectious viruses and pathogenic bacteria. Moreover, advanced nanotechnologies have also been integrated into these biosensors to improve their detection stability, sensitivity, and accuracy. In this review, the recent advance in CRISPR/Cas systems-based nano/biosensors and their applications in the detection of infectious viruses and pathogenic bacteria are comprehensively reviewed. First of all, the categories and working principles of CRISPR/Cas systems for establishing the nano/biosensors are simply introduced. Then, the design and construction of CRISPR/Cas systems-based nano/biosensors are comprehensively discussed. In the end, attentions are focused on the applications of CRISPR/Cas systems-based nano/biosensors in the detection of infectious viruses and pathogenic bacteria. Impressively, the remaining opportunities and challenges for the further design and development of CRISPR/Cas system-based nano/biosensors and their promising applications are proposed.

Abstract
Sensitive monitoring of intracellular uracil-DNA glycosylase (UDG) in living cells is essential to understanding the DNA repair pathways and discovery of anticancer drugs. Herein, we demonstrate the construction of an entropy-driven dumbbell-type DNAzyme assembly circuit for lighting up UDG in living cells via the integration of entropy-driven DNA catalysis (EDC) with the DNAzyme biocatalyst. Target UDG excises the damaged uracil base, causing the breakage of detection probe and the release of trigger. The released trigger can initiate the downstream EDC reaction to form two catalytically active DNAzyme units. The resultant dual Mg2+-DNAzyme units serve as the signal transducers to cyclically cleave the fluorophore/quenched-modified reporters, generating an enhanced fluorescence signal. In contrast to the single-layered EDC method with a linear amplification, the proposed doublet EDC-DNAzyme strategy exhibits high signal gain and achieves a detection limit of 8.71 × 10-6 U/mL. Notably, this assay can be performed in one-step manner at room temperature without the requirement of strict temperature control and complicated reaction procedures, and it can further screen the UDG inhibitors, measure kinetic parameters, and discriminate cancer cells from normal cells. Moreover, this strategy can monitor intracellular UDG activity with improved signal gain, and it may be exploited for sensing and imaging of other types of DNA modifying enzymes with the integration of the corresponding detection substrate, providing a facile and robust approach for biological research studies and clinical diagnosis.

Abstract
We demonstrate for the first time the utilization of fluorogenic RNA aptamers for label-free uracil-DNA glycosylase (UDG) assay. Through rationally engineering the transcription machine with dU substitution, this assay requires only a single probe to simultaneously sense and amplify the UDG signal, achieving a low detection limit of 6.3 × 10-6 U mL-1. Moreover, it can be applied for screening UDG inhibitors and measuring endogenous UDG activity in different cells.

Abstract
The discovery and function analysis of terminal deoxynucleotidyl transferase (TdT) add a new dimension to the understanding of leukemia mechanisms and stimulate the development of new analytical tools for leukemia diagnosis. Herein, taking advantage of the inherent property of TdT for performing DNA synthesis using only single-stranded DNA as the nucleic acid substrate, we developed a self-customized multichannel exponential amplification (SMEA) system for the fluorescent sensing of TdT activity. The SMEA design employs an intermolecular DNA interaction made of a nicking site-incorporated elongation primer (EP) and a nicking site-incorporated poly-thymine tailed molecular beacon (Poly-T-MB). The absence of TdT is unable to bridge the relationship between EP and Poly-T-MB, ensuring the SMEA has an ultralow background. The presence of TdT, however, leads to the elongation of EP to poly-adenine tailed EP (Poly-A-EP) under a dATP pool responsible for further hybridization with numerous Poly-T-MB. With the aid of polymerase and nickase to react with the hybridization product of Poly-A-EP/(Poly-T-MB)n, it can cause bidirectional strand nicking, polymerization, and displacement in many cycles and channels. In this case, the SMEA is found to be associated with the configuration transformation and splitting of all Poly-T-MBs for a significant fluorescence enhancement. Depending on this high target signal amplification and strong background inhibition abilities, the SMEA sensing system is powerful for the qualitative and quantitative determination of TdT activity, showing that it has great promise for biomedical study and disease diagnosis.

Abstract
Uracil-DNA glycosylase (UDG) is a common glycosylase that can expressly recognize and remove damaged uracil bases, and the ultrasensitive detection of which is significant to maintain genomic stability and early clinical diagnosis of disease. Herein, we proposed a sensitive colorimetric sensing platform to detect UDG. Combined with target-manipulated drawstring DNAzyme and Au@Ag nanorods (Au@Ag NRs) indicator, we achieved in naked-eyes observation and ultrasensitive detection of UDG. Briefly, when the UDG exists, the dynamic reaction of rope pulling will occur generating the active conformation of DNAzyme. The cutting effect will be further produced when we add Mg2+, thus the generated trigger chain can mediate the occurrence of CHA reaction, followed by generating amount of ·OH which can etch Au@Ag NRs causing the shifted of localized surface plasmon resonance (LSPR) peak. By contrast, there is no obvious shift of LSPR peak. This strategy shows extraordinary specificity and sensitivity toward UDG providing a detection limit of 4.6 × 10-5 U mL-1. By using of this method, we detected UDG specifically in complex samples, proving that it's potential applications in biomedical research and clinical diagnosis are fantastic.

Abstract
Uracil-DNA glycosylase (UDG) is essential to the maintenance of genomic integrity due to its critical role in base excision repair pathway. However, existing UDG assays suffer from laborious procedures, poor specificity, and limited sensitivity. In this research, we construct a catalytic single-molecule Föster resonance energy transfer (FRET) biosensor for in vitro and in vivo biosensing of UDG activity. Target UDG can remove uracil base from the detection probe and cause the cleavage of detection probe by apurinic/apyrimidinic endonuclease (APE1), which exposes its toehold domain and initiates catalytic assembly of two fluorescently labeled hairpin probes via toehold-meditated strand displacement reaction (SDA) to generate abundant DNA duplexes with amplified FRET signal. In this assay, target UDG signal is amplified via enzyme-free catalytic reaction and the whole reaction may be completed in one step, which greatly simplifies the assay procedure, reduces the assay time, and facilitates the cellular imaging. This biosensor enables specific and sensitive measurement of UDG down to 0.00029 U/mL, and it is suitable for analyzing kinetic parameters, screening inhibitors, and even imaging endogenous UDG in live cells. Importantly, this biosensor can visually quantify various DNA repair enzymes by rationally altering DNA substrates.

Abstract
The trans-cleavage activity of CRISPR/Cas12a has been widely used in biosensing applications. However, the lack of exploration on the fundamental properties of CRISPR/Cas12a not only discourages further in-depth studies of the CRISPR/Cas12a system but also limits the design space of CRISPR/Cas12a-based applications. Herein, a "RESET" effect (random extending sequences enhance trans-cleavage activity) is discovered for the activation of CRISPR/Cas12a trans-cleavage activity. That is, a single-stranded DNA, which is too short to work as the activator, can efficiently activate CRISPR/Cas12a after being extended a random sequence from its 3'-end, even when the random sequence folds into secondary structures. The finding of the "RESET" effect enriches the CRISPR/Cas12a-based sensing strategies. Based on this effect, two CRISPR/Cas12a-based biosensors are designed for the sensitive and specific detection of two biologically important enzymes.

Abstract
Herein, we propose a sensitive fluorescent assay for organophosphorus pesticides (OPs) detection based on a novel strategy of activating the CRISPR-Cas12a system. Specifically, acetylcholinesterase (AChE) hydrolyzes acetylthiocholine into thiocholine (TCh). Subsequently, TCh induces the degradation of MnO2 nanosheets and generates sufficient Mn2+ ions to activate the Mn2+-dependent DNAzyme. Then, as the catalytic product of activated DNAzyme, the short DNA strand activates the CRISPR-Cas12a system to cleave the fluorophore-quencher-labeled DNA reporter (FQ) probe effectively; thus, increasing the fluorescence intensity (FI) in the solution. However, in the presence of OPs, the activity of AChE is suppressed, resulting in a decrease in FI. Under optimized conditions, the limits of detection for paraoxon, dichlorvos, and demeton were 270, 406, and 218 pg/mL, respectively. Benefiting from the outstanding MnO2 nanosheets properties and three rounds of enzymatic signal amplification, the proposed fluorescence assay holds great potential for the detection of OPs in agricultural products.

Abstract
The molecular biomarkers are molecules that are closely related to specific physiological states. Numerous molecular biomarkers have been identified as targets for disease diagnosis and biological research. To date, developing highly efficient probes for the precise detection of biomarkers has become an attractive research field which is very important for biological and biochemical studies. During the past decades, not only the small chemical probe molecules but also the biomacromolecules such as enzymes, antibodies, and nucleic acids have been introduced to construct of biosensor platform to achieve the detection of biomarkers in a highly specific and highly efficient way. Nevertheless, improving the performance of the biosensors, especially in clinical applications, is still in urgent demand in this field. A noteworthy example is the Corona Virus Disease 2019 (COVID-19) that breaks out globally in a short time in 2020. The COVID-19 was caused by the virus called SARS-CoV-2. Early diagnosis is very important to block the infection of the virus. Therefore, during these months scientists have developed dozens of methods to achieve rapid and sensitive detection of the virus. Nowadays some of these new methods have been applied for producing the commercial detection kit and help people against the disease worldwide. DNA-based biosensors are useful tools that have been widely applied in the detection of molecular biomarkers. The good stability, high specificity, and excellent biocompatibility make the DNA-based biosensors versatile in application both in vitro and in vivo. In this paper, we will review the major methods that emerged in recent years on the design of DNA-based biosensors and their applications. Moreover, we will also briefly discuss the possible future direction of DNA-based biosensors design. We believe this is helpful for people interested in not only the biosensor field but also in the field of analytical chemistry, DNA nanotechnology, biology, and disease diagnosis.

Abstract
Cocaine is one of the mainly used illegal drugs in the world. Using the signal amplification elements of terminal deoxynucleotidyl transferase (TdT) and CRISPR-Cas12a, a highly sensitive and simple electrochemical aptasensor was introduced for cocaine quantification. When, no cocaine existed in the sample, the 3'-end of complementary strand of aptamer (CS) was extended by TdT, leading to the activation of CRISPR-Cas12a and remaining of very short oligonucleotides on the working electrode. So, the current signal was remarkably promoted. With the presence of cocaine, CS left the electrode surface. Thus, nothing changed following the incubation of TdT and CRISPR-Cas12a and the Aptamer/Cocaine complex presented on the electrode. Consequently, the [Fe(CN)6]3-/4- could not freely reach the electrode surface and the signal response was weak. Under optimal situations, the biosensor revealed a wide linear relation from 40 pM to 150 nM with detection limit of 15 pM for cocaine. The sensitivity of the analytical system was comparable and even better than other reported methods for cocaine detection. The designed method displayed excellent cocaine selectivity. The aptasensor could work well for cocaine assay in serum samples. So, the aptasensor is expected to be an efficient analytical method with broad applications in the determination of diverse analytes.

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

Abstract
CRISPR–Cas (CC)-based detection technologies have some exceptional features, which hold the promise of developing into the next-generation diagnostic platforms. One of these features is the ability to trigger non-specific single-stranded DNA/RNA cleavage activity after specific target recognition and Cas enzyme activation. This cleavage activity can be visualized either by single-stranded DNA/RNA fluorescence resonance energy transfer quenching reporters or via lateral flow strips, which separate and detect the cleaved reporters. In a previous study, we reported coupling CC-cleavage activity with the enzyme terminal deoxynucleotidyl transferase (TdT) that elongates cleaved ssDNA reporter fragments with dTTP nucleotides. These elongated poly(thymine) tails then act as scaffolds for the formation of copper nanoparticles which generate a bright fluorescent signal upon UV excitation. In the current study, we visualize the poly(thymine) tails on lateral flow strips, using different combinations of biotinylated or fluorescein-labeled nucleotides, various reporters, and capture oligos. One particular approach, using a fluorescein reporter, reached a target sensitivity of <1 pM and was named Cas activity assay on a strip and was tested using Bacillus anthracis genomic DNA.

Abstract
Besides gene-editing, the CRISPR/Cas12a system has also been widely used in in vitro biosensing, but its applications in live-cell biosensing are rare. One reason is lacking appropriate carriers to synchronously deliver all components of the CRISPR/Cas12a system into living cells. Herein, we demonstrate that MnO2 nanosheets are an excellent carrier of CRISPR/Cas12a due to the two important roles played by them. Through a simple mixing operation, all components of the CRISPR/Cas12a system can be loaded on MnO2 nanosheets and thus synchronously delivered into cells. Intracellular glutathione (GSH)-induced decomposition of MnO2 nanosheets not only results in the rapid release of the CRISPR/Cas12a system in cells but also provides Mn2+ as an accelerator to promote CRISPR/Cas12a-based biosensing of intracellular targets. Due to the merits of highly efficient delivery, rapid intracellular release, and the accelerated signal output reaction, MnO2 nanosheets work better than commercial liposome carriers in live-cell biosensing analysis of survivin messenger RNA (mRNA), producing much brighter fluorescence images in a shorter time. The use of MnO2 nanosheets might provide a good carrier for different CRISPR/Cas systems and achieve the rapid and sensitive live-cell biosensing analysis of different intracellular targets, thus paving a promising way to promote the applications of CRISPR/Cas systems in living cells. Herein, we demonstrate that MnO2 nanosheets are an excellent carrier of CRISPR/Cas12a due to the two important roles played by them.![]()
