Abstract
CRISPR-Cas12a system exhibits tremendous potential in accurate recognition and quantitation of nucleic acids and non-nucleic-acid targets thanks to the discovery of its cleavage capability toward single-stranded DNA (ssDNA). In this study, we developed an efficient electrochemiluminescence (ECL) sensing platform based on CRISPR-Cas12a for the analysis of adenosine triphosphate (ATP). In the presence of the target, the successful release of the DNA activator is specially recognized by Cas12a-crRNA duplex and activates the cleavage of ferrocene (Fc) labeled-ssDNA (Fc-ssDNA) modified on the cathode of bipolar electrode (BPE), resulting in a decrease of ECL intensity of [Ru(bpy)3]2+/TPrA in the anodic cell of BPE. By means of the unique combination of Cas12a with ECL technique based on BPE, it can convert the recognition of target ATP into a detectable ECL signal. The detection limit of ATP was determined to be 0.48 nM under the optimal conditions. This work will expand the application of CRISPR-Cas detection system and propose a potential method for the analysis of non-nucleic-acid targets.

Abstract
Base excision repair (BER) is vital for maintaining the integrity of the genome under oxidative damage. DNA glycosylase initiates the BER pathway recognizes and excises the mismatched substrate base leading to the apurinic/apyrimidinic site generation, and simultaneously breaks the single-strand DNA. As the aberrant activity of DNA glycosylase is associated with numerous diseases, including cancer, immunodeficiency, and atherosclerosis, the detection of DNA glycosylase is significant from bench to bedside. In this review, we summarized novel DNA strategies in the past five years for DNA glycosylase activity detection, which are classified into fluorescence, colorimetric, electrochemical strategies, etc. We also highlight the current limitations and look into the future of DNA glycosylase activity monitoring.

Abstract
CRISPR (clustered regularly interspaced short palindromic repeats)/Cas (CRISPR-associated) proteins are powerful gene-editing tools because of their ability to accurately recognize and manipulate nucleic acids. Besides gene-editing function, they also show great promise in biosensing applications due to the superiority of easy design and precise targeting. To improve the performance of CRISPR/Cas-based biosensing systems, various nucleic acid-based signal amplification techniques are elaborately incorporated. The incorporation of these amplification techniques not only greatly increases the detection sensitivity and specificity, but also extends the detectable target range, as well as makes the use of various signal output modes possible. Therefore, summarizing the use of signal amplification techniques in sensing systems and elucidating their roles in improving sensing performance are very necessary for the development of more superior CRISPR/Cas-based biosensors for various applications. In this review, CRISPR/Cas-based biosensors are summarized from two aspects: the incorporation of signal amplification techniques in three kinds of CRISPR/Cas-based biosensing systems (Cas9, Cas12 and Cas13-based ones) and the signal output modes used by these biosensors. The challenges and prospects for the future development of CRISPR/Cas-based biosensors are also discussed.

Abstract
The CRISPR/Cas technology, derived from an adaptive immune system in bacteria, has been awarded the Nobel Prize in Chemistry in 2020 for its success in gene editing. Increasing reports reveal that CRISPR/Cas technology has a wide scope of applications and it could be incorporated into biosensors for detecting critical analytes. CRISPR-powered biosensors have attracted significant research interest due to their advantages including high accuracy, good specificity, rapid response, and superior integrity. Now the CRISPR technology is not only admirable in nucleic acid monitoring, but also promising for other kinds of biomarkers' detection, including metal ions, small molecules, peptides, and proteins. Therefore, it is of great worth to explore the prospect, and summarize the strategies in applying CRISPR technology for the recognition of a broad range of targets. In this review, we summarized the strategies of CRISPR biosensing for non-nucleic-acid analytes, the latest development of nucleic acid detection, and proposed the challenges and outlook of CRISPR-powered biosensors.

Abstract
In addition to their roles as revolutionary genome engineering tools, CRISPR-Cas systems are also highly promising candidates in the construction of biosensing systems and diagnostic devices, which have attracted significant attention recently. However, the CRISPR-Cas system cannot be directly applied in the sensing of non-nucleic acid targets, and the needs of synthesizing and storing different vulnerable guide RNA for different targets also increase the application and storage costs of relevant biosensing systems, and therefore restrict their widespread applications. To tackle these barriers, in this work, a versatile CRISPR-Cas12a-based biosensing platform was developed through the introduction of an enzyme-free and robust DNA reaction network, the entropy-driven dynamic DNA network. By programming the sequences of the system, the entropy-driven catalysis-based dynamic DNA network can respond to different types of targets, such as nucleic acids or proteins, and then activate the CRISPR-Cas12a to generate amplified signals. As a proof of concept, both nucleic acid targets (a DNA target with random sequence, T, and an RNA target, microRNA-21 (miR-21)) and a non-nucleic acid target (a protein target, thrombin) were chosen as model analytes to address the feasibility of the designed sensing platform, with detection limits at the pM level for the nucleic acid analytes (7.4 pM for the DNA target T and 25.5 pM for miR-21) and 0.4 nM for thrombin. In addition, the detection of miR-21 or thrombin in human serum samples further demonstrated the applicability of the proposed biosensing platform in real sample analysis.

Abstract
Uracil DNA glycosylase (UDG) is a key base excision repair (BER) enzyme and its abnormal expression is nearly relevant to several diseases including cancer. The sensitive detection of UDG activity is beneficial for biomedical studies and clinic diagnosis. In this work, we proposed a dumbbell probe mediated triple cascade signal amplification strategy for sensitive and specific detection of UDG activity. The specially designed dumbbell probe contained two uracil bases, two recognition sites for nicking enzyme and a split sequence of DNAzyme. Unsealed dumbbell probes were first connected into sealed dumbbell probes by T4 DNA ligase, and then the unsealed probes were hydrolyzed by exonuclease to ensure the purity of probes. Under the influence of UDG, two uracil bases were removed to produce two apyrimidinic (AP) sites, which were subsequently cleaved by Endo.IV. The probes after cleavage acted as primers and templates for double nicking sites strand displacement amplification (SDA) to produce a mass of two products. The products of SDA continued to act as primers and templates for rolling circle amplification (RCA) to produce repeats containing complete DNAzyme sequences. The DNAzyme repeatedly cleaved multiple molecular beacons (MB), resulting in remarkable fluorescence enhancement. Benefiting from the triple cascade signal amplification, the sensitivity was improved and the detection limit was 7.2 × 10-5 U mL-1. The method could well distinguish UDG from other interfering enzymes and detect UDG activity in real biological samples, showing good specificity. In addition, this method could be used for screening inhibitors. The above results suggested that the method provided a promising analytical means for UDG related biomedical research and clinic diagnosis.

Abstract
Herein, we report a method that combined "aptamer-locker" DNA with CRISPR/Cas12a-based biosensing for sensitive and rapid melamine analysis. Three strategies were harnessed for designing the DNA sensors that were well characterized by circular dichroism (CD) spectroscopy and isothermal titration calorimetry (ITC) in the absence and presence of melamine. The detection parameters were optimized to achieve good analytic performance. As a result, a limit of detection (LOD) as low as 38 nM was achieved, which is below the threshold (1.0 mg/kg) of allowable melamine in infant milk products. In addition, the sensors show high selectivity for melamine against other analogues such as cyanuric acid, ammeline and ammelide. Moreover, our method was effective for rapid melamine analysis in whole milk samples, with or without sample pretreatment, in less than 20 min. Adopting a commercially available portable fluorimeter, on-site analysis of melamine in milk was accomplished. The strategies demonstrated here can expand to detect other non-nucleic-acid targets by simply replacing the aptamers.
