Abstract
The dysregulation of microRNA (miRNA) expression levels is intricately linked to a myriad of human diseases, and the precise and delicate detection thereof holds paramount significance in the realm of clinical diagnosis and therapy. Herein, a near-infrared (NIR) light-mediated homogeneous photoelectrochemical (PEC) biosensor was constructed for miRNA-155 detection based on NaYF4: Yb, Tm@ZnIn2S4 (NYF@ ZIS) coupled with a three-dimensional (3D) walking nanomotor-assisted CRISPR/Cas12a strategy. The upconverted light emitted by the NYF in the visible and UV region upon NIR light excitation could be utilized to excite ZIS to produce a photocurrent response. The presence of target miRNA-155 initiated an amplification reaction within the 3D walking nanomotor, resulting in the production of multiple nucleic acid fragments. These fragments could activate the collateral cleavage capability of CRISPR/Cas12a, leading to the indiscriminate cleavage of single-stranded DNA (ssDNA) on ALP-ssDNA-modified magnetic beads and the subsequent liberation of alkaline phosphatase (ALP). The released ALP facilitated the catalysis of ascorbic acid 2-phosphate to generate ascorbic acid as the electron donor to capture the photogenerated holes on the NYF@ZIS surface, resulting in a positively correlated alteration in the photocurrent response. Under optimal conditions, the NIR light-initiated homogeneous PEC biosensor had the merits of good linear range (0.1 fM to 100 pM), an acceptable limit of detection (65.77 aM) for miRNA-155 detection. Considering the pronounced sensitivity, light stability, and low photodamage, this strategy presents a promising platform for detecting various other miRNA biomarkers in molecular diagnostic practice.

Abstract
An ortho-nitrobenzyl phosphate ester-caged nucleic acid hairpin structure coupled to the CRISPR-Cas12a complex is introduced as a functional reaction module for the light-induced activation of the CRISPR-Cas12a (LAC12a) machinery toward the amplified fluorescence detection of microRNA-21 (miRNA-21). The LAC12a machinery is applied for the selective, in vitro sensing of miRNA-21 and for the intracellular imaging of miRNA-21 in different cell lines. The LAC12a system is used to image miRNA-21 in different cell cycle phases of MCF-7 cells. Moreover, the LAC12a machinery integrated in cells enables the two-photon laser confocal microscopy-assisted, light-stimulated spatiotemporal, selective activation of the CRISPR-Cas12a miRNA-21 imaging machinery at the single-cell level and the evaluation of relative expression levels of miRNA-21 at distinct cell cycle phases. The method is implemented to map the distribution of cell cycle phases in an array of single cells.

Abstract
Rapid and sensitive detection of nucleic acids has become crucial in various fields. However, most current nucleic acid detection methods can only be used in specific scenarios, such as RT-qPCR, which relies on fluorometer for signal readout, limiting its application at home or in the field due to its high price. In this paper, a universal nucleic acid detection platform combing CRISPR/Cas12a and strand displacement amplification (CRISPR-SDA) with multiple signal readout was established to adapt to different application scenarios. Nucleocapsid protein gene of SARS-CoV-2 (N gene) and hepatitis B virus (HBV) DNA were selected as model targets. The proposed strategy achieved the sensitivity of 53.1 fM, 0.15 pM, and 1 pM for N gene in fluorescence mode, personal glucose meter (PGM) mode and lateral flow assay (LFA) mode, respectively. It possessed the ability to differentiate single-base mismatch and the presence of salmon sperm DNA with a mass up to 105-fold of the targets did not significantly interfere with the assay signal. The general and modular design idea made CRISPR-SDA as simple as building blocks to construct nucleic acid sensing methods to meet different requirements by simply changing the SDA template and selecting suitable signal report probes, which was expected to find a breadth of applications in nucleic acids detection.

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
We propose a sensitive H1N1 virus fluorescence biosensor based on ligation-transcription and CRISPR/Cas13a-assisted cascade amplification strategies. Products are generated via the hybridization of single-stranded DNA (ssDNA) probes containing T7 promoter and crRNA templates to a target RNA sequence using SplintR ligase. This generates large crRNA quantities in the presence of T7 RNA polymerase. At such crRNA quantities, ternary Cas13a, crRNA, and activator complexes are successfully constructed and activate Cas13a to enhance fluorescence signal outputs. The biosensor sensitively and specifically monitored H1N1 viral RNA levels down to 3.23 pM and showed good linearity when H1N1 RNA concentrations were 100 pM-1 µM. Biosensor specificity was also excellent. Importantly, our biosensor may be used to detect other viral RNAs by altering the sequences of the two probe junctions, with potential applications for the clinical diagnosis of viruses and other biomedical studies.

Abstract
The precise determination of DNA methylation at specific sites is critical for the timely detection of cancer, as DNA methylation is closely associated with the initiation and progression of cancer. Herein, a novel ratiometric fluorescence method based on the methylation-sensitive restriction enzyme (MSRE), CRISPR/Cas12a, and catalytic hairpin assembly (CHA) amplification were developed to detect site-specific methylation with high sensitivity and specificity. In detail, AciI, one of the commonly used MSREs, was employed to distinguish the methylated target from nonmethylated targets. The CRISPR/Cas12a system was utilized to recognize the site-specific target. In this process, the protospacer adjacent motif and crRNA-dependent identification, the single-base resolution of Cas12a, can effectively ensure detection specificity. The trans-cleavage ability of Cas12a can convert one target into abundant activators and can then trigger the CHA reaction, leading to the accomplishment of cascaded signal amplification. Moreover, with the structural change of the hairpin probe during CHA, two labeled dyes can be spatially separated, generating a change of the Förster resonance energy transfer signal. In general, the proposed strategy of tandem CHA after the CRISPR/Cas12a reaction not only avoids the generation of false-positive signals caused by the target-similar nucleic acid but can also improve the sensitivity. The use of ratiometric fluorescence can eradicate environmental effects by self-calibration. Consequently, the proposed approach had a detection limit of 2.02 fM. This approach could distinguish between colorectal cancer and precancerous tissue, as well as between colorectal patients and healthy people. Therefore, the developed method can serve as an excellent site-specific methylation detection tool, which is promising for biological and disease studies.

Abstract
In this work, we demonstrate for the first time the application of the phosphorothioated-terminal hairpin formation and self-priming extension (PS-THSP) reaction for miRNA assays. A self-priming amplification accelerating CRISPR sensor was well-established for sensitive and specific miRNA detection by integrating the PS-THSP reaction and CRISPR/Cas12a system. The sensor consists of three steps: (1) the formation of a complete PS-THSP template in the presence of target miRNA and ligase; (2) the exponential isothermal amplification of the PS-THSP reaction under the action of DNA polymerase; (3) the activation of the CRISPR/Cas12a fluorescence system to generate signals. We used miR-21 as a model target. The sensor can achieve sensitive detection of miR-21 without the involvement of any primers, and the special design of the CRISPR proto-spacer neighbor motif (PAM) sequence effectively avoids the interference of the background signal. In addition, the sensor can not only identify single-base mutant homologous sequences but also show stable performance in complex biological matrices. We have successfully used this sensor to accurately analyze miR-21 in different cell lines and real clinical samples, demonstrating its great potential in clinical diagnosis.

Abstract
The lack of point-of-use (POU) methods hinders the utilization of the hgcA gene to rapidly evaluate methylmercury risks. CRISPR/Cas12a is a promising technology, but shortcomings such as low sensitivity, a strict reaction temperature and high background signal limit its further utilization. Here, a thermally stable microsystem-based CRISPR/Cas12a biosensor was constructed to achieve POU analysis for hgcA. First, three target gRNAs were designed to recognize hgcA. Then, a microsystem was developed to eliminate the background signal. Next, the effect of temperature on the activity of the Cas12a-gRNA complex was explored and its thermal stability was discovered. After that, coupling gRNA assay was introduced to improve sensitivity, exhibiting a limit of detection as low as 0.49 pM with a linear range of 0.98-125 pM, and a recovery rate between 90 and 110 % for hgcA. The biosensor was finally utilized to assess hgcA abundance in paddy soil, and high abundance of hgcA was found in these paddy soil samples. This study not only systematically explored the influence of temperature and microsystem on CRISPR/Cas12a, providing vital references for other novel CRISPR-based detection methods, but also applied the CRISPR-based analytical method to the field of environmental geochemistry for the first time, demonstrating enormous potential for POU detection in this field.

Abstract
Wastewater is among the main sources of antibiotic resistance genes (ARGs) in the environment, but effective methods to quickly assess ARGs on-site in wastewater are lacking. Here, using the typical ARG ermB as the target, we report a portable biosensor combining CRISPR/Cas12a and loop-mediated isothermal amplification (LAMP) for the detection of ARGs. Six primers of LAMP and the crRNA of CRISPR/Cas12a were first designed to be preamplification with LAMP and lead Cas12a to recognize the ermB via base pairing. Due to the trans-cleavage activity of CRISPR/Cas12a after amplicon recognition, ssDNA probes modified with reporter molecules were used to implement a visual assay with lateral flow test strips and fluorescence. After a simple nucleic acid extraction with magnetic beads, the constructed biosensor possesses excellent sensitivity and selectivity as low as 2.75 × 103 copies/μL using fluorescence and later flow strips in wastewater. We further evaluated the community-wide prevalence of ermB in wastewater influent and found high mass loads of ermB during different months. This user-friendly and low-cost biosensor is applicable for rapid on-site ARG detection, providing a potential point-of-use method for rapid assessments of ARG abundance in wastewater from large city areas with many wastewater treatment plants and in resource-limited rural areas.

Abstract
The use of microRNAs as clinical cancer biomarkers is hindered by the absence of accurate, fast and inexpensive assays for their detection in biofluids. Here we report a one-step and one-pot isothermal assay that leverages rolling-circle amplification and the endonuclease Cas12a for the accurate detection of specific miRNAs. The assay exploits the cis-cleavage activity of Cas12a to enable exponential rolling-circle amplification of target sequences and its trans-cleavage activity for their detection and for signal amplification. In plasma from patients with pancreatic ductal adenocarcinoma, the assay detected the miRNAs miR-21, miR-196a, miR-451a and miR-1246 in extracellular vesicles at single-digit femtomolar concentrations with single-nucleotide specificity. The assay is rapid (sample-to-answer times ranged from 20 min to 3 h), does not require specialized instrumentation and is compatible with a smartphone-based fluorescence detection and with the lateral-flow format for visual readouts. Simple assays for the detection of miRNAs in blood may aid the development of miRNAs as biomarkers for the diagnosis and prognosis of cancers.

Abstract
Simultaneous detection of multiple targets can provide important data support for clinical diagnosis and treatment. Here, we report a facile isothermal assay based on target-mediated rolling circle transcription coupling with CRISPR/Cas12a-Cas13a (TM-RCT/Cas12a-Cas13a). Through facile one-step amplification (TM-RCT), two target DNAs are converted to RNA amplified products. The simultaneous detection of HPV16 and HPV18 is then achieved by combining two CRISPR/Cas systems. This system shows excellent sensing performance and provides a universal method for simultaneous detection.

Abstract
As the up-and-comer in the development of RNA nanotechnology, RNA nanomaterials based on functionalized rolling circle transcription (RCT) have become promising carriers for drug production and delivery. This is due to RCT technology can self-produce polyvalent tandem nucleic acid prodrugs for intervention in intracellular gene expression and protein production. RNA component strands participating in de novo assembly enable RCT-based nanomaterials to exhibit good mechanical properties, biostability, and biocompatibility as delivery carriers. The biostability makes it to suitable for thermodynamically/kinetically favorable assembly, enzyme resistance and efficient expression in vivo. Controllable RCT system combined with polymers enables customizable and adjustable size, shape, structure, and stoichiometry of RNA building materials, which provide groundwork for the delivery of advanced drugs. Here, we review the assembly strategies and the dynamic regulation of RCT-based nanomaterials, summarize its functional properties referring to the bottom-up design philosophy, and describe its advancements in tumor gene therapy, synergistic chemotherapy, and immunotherapy. Last, we elaborate on the unique and practical value of RCT-based nanomaterials, namely "self-production and self-sale", and their potential challenges in nanotechnology, material science and biomedicine.

Abstract
Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) technology has transformed oncology research in many ways. Breast cancer is the most prevalent malignancy globally and triple negative breast cancer (TNBC) is one of the most aggressive subtypes with numerous challenges still to be faced. In this work, we have explained what CRISPR consists of and listed its applications in breast cancer while focusing on TNBC research. These are disease modelling, the search for novel genes involved in tumour progression, sensitivity to drugs and immunotherapy response, tumour fitness, diagnosis, and treatment. Additionally, we have listed the current delivery methods employed for the delivery of CRISPR systems in vivo. Lastly, we have highlighted the limitations that CRISPR technology is subject to and the future directions that we envisage. Overall, we have provided a round summary of the aspects concerning CRISPR in breast cancer/TNBC research.

Abstract
The development of an array for high-throughput and logical analysis of biomarkers is significant for disease diagnosis. DNA-templated copper nanoclusters (CuNCs) have a strong potential to serve as a label-free photoluminescence source in array platforms, but their luminescent stability and sensitivity need to be improved. Herein, we report a facile, sensitive, and robust biomimetic array assay by integrating with stable luminescent CuNCs and entropy-driven nanomachine (EDN). In this strategy, the luminescent stability of CuNCs was improved by adding fructose in CuNCs synthesis to offer a reliable label-free signal. Meanwhile, the DNA template for CuNCs synthesis was introduced into EDN with excellent signal amplification ability, in which the reaction triggered by target miRNA would cause the blunt/protruding conformation change of 3'-terminus accompanied by the production or loss of luminescence. In addition, a biomimetic array fabricated by photonic crystals (PCs) physically enhanced the emitted luminescent signal of CuNCs and achieved high-throughput signal readout by a microplate reader. The proposed assay can isothermally detect as low as 4.5 pM of miR-21. Moreover, the logical EDN was constructed to achieve logical analysis of multiple miRNAs by "AND" or "OR" logic gate operation. Therefore, the proposed assay has the advantages of label-free property, high sensitivity, flexible design, and high-throughput analysis, which provides ideas for developing a new generation of facile and smart platforms in the fields of biological analysis and clinical application.

Abstract
In this study, a cathodic photoelectrochemical (PEC) bioanalysis for sensitive determination of microRNA (miRNA) has been constructed based on CRISPR/Cas12a trans-cleavage mediated [(C6)2Ir(dcbpy)]+PF6- (C6 represents coumarin-6 and dcbpy represents 4,4'-dicarboxyl-2,2'-bipyridine)-sensitized NiO photocathode and p-n heterojunction quenching mode. The [(C6)2Ir(dcbpy)]+PF6--sensitized NiO photocathode exhibits a stable and dramatically improved photocurrent signal due to highly effective photosensitization of [(C6)2Ir(dcbpy)]+ PF6-. Then Bi2S3 quantum dots (Bi2S3 QDs) is captured on the photocathode, resulting in markedly quenching of the photocurrent. When target miRNA is specifically recognized by the hairpin DNA to stimulate the trans-cleavage activity of CRISPR/Cas12a, leading to the leave of the Bi2S3 QDs. The photocurrent is gradually recovered with the increasing target concentration. Thus, the quantitative signal response to target is achieved. Benefiting from excellent performance of NiO photocathode, intense quenching effect of p-n heterojunction and accurate recognition ability of CRISPR/Cas12a, the cathodic PEC biosensor shows a wider linear range over 0.1 fM-10 nM, with a low detection limit of 36 aM. Also, the biosensor exhibits satisfying stability and selectivity.

Abstract
Rapid and accurate detection of biomarkers was very important for early screening and treatment of diseases. Herein, a sensitive and amplification-free electrochemiluminescence (ECL) biosensor based on CRISPR/Cas12a and DNA tetrahedron nanostructures (TDNs) was constructed. Briefly, 3D TDN was self-assembled on the Au nanoparticle-deposited glassy carbon electrode surface to construct the biosensing interface. The presence of the target would activate the trans-cleavage activity of Cas12a-crRNA duplex to cleave the single-stranded DNA signal probe on the vertex of TDN, causing the Ru(bpy)32+ to fall from the electrode surface and weakened the ECL signal. Thus, the CRISPR/Cas12a system transduced the change of target concentration into an ECL signal enabling the detection of HPV-16. The specific recognition of CRISPR/Cas12a to HPV-16 made the biosensor have good selectivity, while the TDN-modified sensing interface could reduce the cleaving steric resistance and improve the cleaving performance of CRISPR/Cas12a. In addition, the pretreated biosensor could complete sample detection within 100 min with a detection limit of 8.86 fM, indicating that the developed biosensor possesses the potential application prospect for fast and sensitive nucleic acid detection.

Abstract
MicroRNAs (miRNAs) play a crucial role in the regulation of gene expression and have been implicated in many diseases. Herein, we develop a target triggered exponential rolling-circle amplification coupling with CRISPR/Cas12a (T-ERCA/Cas12a) system, which can achieve the ultrasensitive detection with simple operation and no annealing procedure. In this assay, T-ERCA combines the exponential amplification with rolling-circle amplification by introducing a dumb-bell probe with two enzyme recognition sites. miRNA-155 targets are activators that trigger exponential rolling circle amplification to produce large amounts of ssDNA, which is then recognized by CRISPR/Cas12a for further amplification. Compared with single EXPAR or RCA combined with CRISPR/Cas12a, this assay shows higher amplification efficiency. Therefore, benefiting from the excellent amplification effect of T-ERCA and the high recognition specificity of CRISPR/Cas12a, the proposed strategy shows a wide detection range from 1 fM to 5 nM with a LOD (limit of detection) down to 0.31 fM. Moreover, it shows good application ability for assessing miRNA levels in different cells, indicating that the T-ERCA/Cas12a may provide a new guidance for molecular diagnosis and clinical practical application.

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
As a major epigenetic modification, DNA methylation participates in diverse cellular functions and emerges as a promising biomarker for disease diagnosis and monitoring. Herein, we developed a methylation-sensitive transcription-enhanced single-molecule biosensor to detect DNA methylation in human cells and tissues. In this biosensor, a rationally designed transcription machine is split into two parts including a promoter sequence (probe-P) for initiating transcription and a template sequence (probe-T) for RNA synthesis. The presence of specific DNA methylation leads to the formation of full-length transcription machine through sequence-specific ligation of probe-P and probe-T, initiating the synthesis of abundant ssRNA transcripts. The resultant ssRNAs can activate CRISPR/Cas12a to catalyze cyclic cleavage of fluorophore- and quencher-dual labeled signal probes, resulting in the recovery of the fluorophore signal that can be quantified by single-molecule detection. Taking advantages of the high-fidelity ligation of split transcription machine and the high efficiency of transcription- and CRISPR/Cas12a cleavage-mediated dual signal amplification, this single-molecule biosensor achieves a low detection limit of 337 aM and high selectivity. Moreover, it can distinguish 0.01% methylation level, and even accurately detect genomic DNA methylation in single cell and clinical samples, providing a powerful tool for epigenetic researches and clinical diagnostics.

Abstract
MicroRNAs (miRNAs) are a class of endogenous short noncoding RNA. They regulate gene expression and function, essential to biological processes. It is necessary to develop an efficient detection method to determine these valuable biomarkers for the diagnosis of cancers. In this paper, we proposed a general and rapid method for sensitive and quantitative detection of miRNA by combining CRISPR-Cas12a and rolling circle amplification (RCA) with the precircularized probe. Eventually, the detection of miRNA-21 could be completed in 70 min with a limit of detection of 8.1 pM with high specificity. The reaction time was reduced by almost 4 h from more than 5 h to 70 min, which makes detection more efficient. This design improves the efficiency of CRISPR-Cas and RCA-based sensing strategy and shows great potential in lab-based detection and point-of-care test.

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
In this study, we combined a rolling circle transcription (RCT) system producing 22AG G-quadruplex RNA with a QnMorpholine (QNM) fluorescent probe for the selective and sensitive detection of alkaline phosphatase (ALP). ALP is involved in various biological functions, with monophosphate cleavage being one of its characteristic properties. Here, we developed a padlock RCT probing system in which a large amount of RCT 22AG RNA G-quadruplex was produced in the absence of ALP, providing a high fluorescence signal. In contrast, no RNA G-quadruplex was produced in the presence of ALP, with minimal fluorescence. This huge deviation in signal intensity allowed us to identify the presence or absence of ALP in a test sample. Under practical conditions, our system allowed the differentiation for ALP even when it was present at an extremely low concentration (0.0085 U/L), along with very high specificity. The simplicity and efficiency of this approach for ALP detection suggest its potential for use as a reliable diagnostic tool.

Abstract
Recent advances in CRISPR-based biotechnologies have greatly expanded our capabilities to repurpose CRISPR for the development of molecular diagnostic systems. The key attribute that allows CRISPR to be widely utilized is its programmable and highly specific nature. In this review, we first illustrate the principle of the class 2 CRISPR nucleases for molecular diagnostics which originates from their immunologic defence systems. Next, we present the CRISPR-based schemes in the application of diagnostics with amplification-assisted or amplification-free strategies. By highlighting some of the recent advances we interpret how general bioengineering methodologies can be integrated with CRISPR. Finally, we discuss the challenges and exciting prospects for future CRISPR-based biosensing development. We hope that this review will guide the reader to systematically learn the start-of-the-art development of CRISPR-mediated nucleic acid detection and understand how to apply the CRISPR nucleases with different design concepts to more general applications in diagnostics and beyond.

Abstract
Herein, a chemiluminescence (CL) biosensor based on CRISPR-Cas12a and cation exchange reaction was constructed to detect the biomarker microRNA-21 (miRNA-21). The rolling circle amplification (RCA) reaction was introduced to convert each target RNA strand into a long single-stranded DNA with repeated sequences, which acted as triggers to initiate the transcleavage activity of CRISPR-Cas12a. The activated Cas12a could cleave the biotinylated linker DNA of CuS nanoparticles (NPs) to inhibit the binding of CuS NPs to streptavidin immobilized on the surface of the microplate, which strongly reduced the generation of Cu2+ from a cation exchange between CuS NPs and AgNO3, and thus efficiently suppressed the CL of Cu2+-luminol-H2O2 system, giving a "signal off" biosensor. With the multiple amplification, the detection limit of the developed sensor for miRNA-21 reached 16 aM. In addition, this biosensor is not only suitable for a professional chemiluminescence instrument but also for a smartphone used as a detection tool for the purpose of portable and low-cost assay. This method could be used to specifically detect quite a low level of miRNA-21 in human serum samples and various cancer cells, indicating its potential in ultrasensitive molecular diagnostics.

Abstract
Sensitive and specific assay of microRNAs (miRNAs) is beneficial to early disease screening. Herein, we for the first time proposed clustered regularly interspaced short palindromic repeats (CRISPR)/Cas13a-mediated photoelectrochemical biosensors for the direct assay of miRNA-21. In this study, compared with traditional nucleic acid-based signal amplification strategies, the CRISPR/Cas13a system can greatly improve the specificity and sensitivity of target determination due to its accurate recognition and high-efficient trans-cleavage capability without complex nucleic acid sequence design. Moreover, compared with the CRISPR/Cas12a-based biosensing platform, the developed CRISPR/Cas13a-mediated biosensor can directly detect RNA targets without signal transduction from RNA to DNA, thereby avoiding signal leakage and distortion. Generally, the proposed biosensor reveals excellent analysis capability with a wider linear range from 1 fM to 5 nM and a lower detection limit of 1 fM. Additionally, it also shows satisfactory stability in the detection of human serum samples and cell lysates, manifesting that it has great application prospects in the areas of early disease diagnosis and biomedical research.

Abstract
Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and Clustered Regularly Interspaced Short Palindromic Repeats-Associated Proteins (CRISPR-Cas) have promising prospects in the field of nucleic acid molecular diagnostics. However, Clustered Regularly Interspaced Short Palindromic Repeats-based fluorescence detection technology is mainly hindered by proteins with conjugated double bonds and autofluorescence, resulting in high fluorescence background, low sensitivity and incompatible reaction systems, which are not conducive to automatic clinical testing. Chemiluminescence (CL) detection technology has been applied mainly owing to its greatly high sensitivity, as well as low background and rapid response. Therefore, we developed a rapid, ultrasensitive and economical detection system based on Clustered Regularly Interspaced Short Palindromic Repeats-Clustered Regularly Interspaced Short Palindromic Repeats-Associated Proteins 13a combined with magnetic beads (MBs) and chemiluminescence (CL) (Cas13a-MB-CL) to detect Influenza A (H7N9), an acute respiratory tract infectious disease. The carboxyl functionalized magnetic beads (MBs-COOH) were covalently coupled with aminated RNA probe while the other end of the RNA probe was modified with biotin. Alkaline phosphatase labeled streptavidin (SA-ALP) binds with biotin to form magnetic beads composites. In presence of target RNA, the collateral cleavage activity of Cas13a was activated to degrade the RNA probes on MBs and released Alkaline phosphatase from the composites. The composites were then magnetically separated followed by addition of ALP substrate Disodium 2-chloro-5-{4-methoxyspiro [1,2-dioxetane-3,2'-(5'-chloro) tricyclo (3.3.1.13,7) decan]-4-yl}-1-phenyl phosphate (CDP-star), to generate the chemiluminescence signal. The activity of Associated Proteins 13a and presence of target RNA was quantified by measuring the chemiluminescence intensity. The proposed method accomplished the detection of H7N9 within 30 min at 25°C. When combined with Reverse Transcription- Recombinase Aides Amplification (RT-RAA), the low detection limit limit of detection was as low as 19.7 fM (3S/N). Our proposed MB-Associated Proteins 13a-chemiluminescence was further evaluated to test H7N9 clinical samples, showing superior sensitivity and specificity.

Abstract
Besides the critical role in gene editing, CRISPR/Cas system also brings a new signal amplification mechanism to the development of next generation biosensing technologies. Herein, we have developed a versatile CRISPR/Cas12a sensing platform by combining a target protection-based transcription amplification strategy with the Cas12a-based signal amplification mechanism, which allows for the sensitive detection of both nucleic acid and non-nucleic acid targets. In this design, a rationally designed transcription template sequence is able to avoid Exonuclease I (Exo I) degradation only in the existence of the target-mediated binding events including either nucleic acid hybridization or protein-based affinity interactions. This target binding-induced protection effect can facilitate the subsequent transcription amplification to generate crRNA and activate the subsequent Cas12a trans-cleavage signal amplification mechanism to yield target dosage-responsive fluorescence signal. In contrast, if the target is absent, the protection-free transcription template will be completely digested by Exo I, thus no fluorescence response is produced. This new strategy well eliminates the T7 polymerase-associated non-specific transcription background and realizes the sensitive detection of various kinds of biomolecules including microRNA, protein, as well as exosome, broadening the application scenarios of CRISPR/Cas system in the field of bioanalysis and biosensing.

Abstract
Sensitive detection methods for T4 polynucleotide kinase/phosphatase (T4 PNKPP) are urgently required to obtain information on malignancy and thereby to provide better guidance in PNKP-related diagnostics and drug screening. Although the CRISPR/Cas12a system shows great promise in DNA-based signal amplification protocols, its guide RNAs with small molecular weight often suffer nuclease degradation during storage and utilization, resulting in reduced activation efficiency. Herein, we proposed a self-supplying guide RNA-mediated CRISPR/Cas12a system for the sensitive detection of T4 PNKP in cancer cells, in which multiple copies of guide RNA were generated by in situ transcription. In this assay, T4 PNKP was chosen as a model, and a dsDNA probe with T7 promoter region and the transcription region of guide RNA were involved. Under the action of T4 PNKP, the 5'-hydroxyl group of the dsDNA probe was converted to a phosphate group, which can be recognized and digested by Lambda Exo, resulting in dsDNA hydrolysis. The transcription template was destroyed, which resulted in the failure to generate guide RNA by the transcription pathway. Therefore, the CRISPR/Cas12a system could not be activated to effectively cleavage the F-Q-reporter, and the fluorescence signal was turned off. In the absence of T4 PNKP, the 5'-hydroxyl group of the substrate DNA cannot be digested by Lambda Exo. The intact dsDNA acts as the transcription template to generate a large amount of guide RNA. Finally, the formed Cas12a/gRNA complex triggered the reverse cleavage of Cas12a on the F-Q-reporter, resulting in a "turn-on" fluorescence signal. This strategy displayed sharp sensitivity of T4 PNKP with the limit of detection (LOD) down to 0.0017 mU/mL, which was mainly due to the multiple regulation effect of transcription amplification. In our system, the dsDNA simultaneously serves as the T4 PNKP substrate, transcription template, and Lambda Exo substrate, avoiding the need for multiple probe designs and saving costs. By integrating the target recognition, Lambda Exo activity, and trans-cleavage activity of Cas12a, CRISPR/Cas12a catalyzed the cleavage of fluorescent-labeled short-stranded DNA probes and enabled synergetic signal amplification for sensitive T4 PNKP detection. Furthermore, the T4 PNKP in cancer cells has been evaluated as a powerful tool for biomedical research and clinical diagnosis, proving a good practical application capacity.

Abstract
CRISPR/Cas12a has shown great potential in molecular diagnostics, but its application in sensing of microRNAs (miRNAs) was limited by sensitivity and complexity. Here, we have sensitively and conveniently detected microRNAs by reasonably integrating metal-organic frameworks (MOFs) based biobarcodes with CRISPR/Cas12a assay (designated as MBCA). In this work, DNA-functionalized Zr-MOFs were designed as the converter to convert and amplify each miRNA target into activators that can initiate the trans-cleavage activity of CRISPR/Cas12a to further amplify the signal. Such integration provides a universal strategy for sensitive detection of miRNAs. By tuning the complementary sequences modified on nanoprobes, this assay achieves subattomolar sensitivity for different miRNAs and was selective to single-based mismatches. With the proposed method, the expression of miR-21 in different cancer cells can be assessed, and breast cancer patients and healthy individuals can be differentiated by analyzing the target miRNAs extracted from serum samples, holding great potential in clinical diagnosis.

Abstract
A novel label-free photoelectrochemical (PEC) biosensor is presented in this work. As a barrier, the DNA hydrogel could block the coupling between g-C3N4 and CdS quantum dots (QDs). Therefore, extremely low photocurrent signals were obtained. The presence of target microRNA-21 can initiate the rolling circle amplification (RCA) reaction, which in turn produces many repeated sequences to activate the CRISPR/Cas12a system. The trans-cleavage activity of the CRISPR/Cas12a system led to the degradation of DNA hydrogels efficiently. As a result, the g-C3N4/CdS QDs heterojunction was formed through "click" chemistry. Through the amplification of the RCA and CRISPR/Cas12a system, the sensitivity of the PEC biosensor was improved significantly with the detection limit of 3.2 aM. The proposed sensor also showed excellent selectivity and could be used to detect actual samples. In addition, the modular design could facilitate the detection of different objects. Thus, the proposed CRISPR/Cas12a system responsive DNA hydrogel provides a simple, sensitive, and flexible way for label-free PEC analysis.

Abstract
MicroRNAs (miRNAs) play a very important role in biological processes and are used as biomarkers for the detection of a variety of diseases, including neurodegenerative diseases, chronic cardiovascular diseases, and cancers. A sensitive point-of-care (POC) method is crucial for detecting miRNAs. Herein, CRISPR-Cas12a combined with the click chemistry actuated exponential amplification reaction was introduced into an electrochemical biosensor for detecting miRNA-21. The target miRNA-21 initiated the click chemistry-exponential amplification reaction in the electrochemical biosensor to produce numerous nucleic acid fragments, which could stimulate the trans-cleavage ability of CRISPR-Cas12a to cleave hairpin DNA electrochemical reporters immobilized on the electrode surface. Under optimal conditions, the minimum detection limit for this electrochemical biosensor was as low as 1 fM. Thus, the proposed electrochemical biosensor allows sensitive and efficient miRNA detection and could be a potential analysis tool for POC test and field molecular diagnostics.

Abstract
As a critical functional protein in DNA replication and genome stability, flap endonuclease 1 (FEN1) has been considered a promising biomarker and druggable target for multiple cancers. We report here a transcription-powered clustered regularly interspaced short palindromic repeat (CRISPR)/Cas12a signal expansion platform for rapid and sensitive detection of FEN1. In this method, the probe cleavage by FEN1 generated a free 5' flap single-stranded DNA which could hybridize with the single-stranded T7 promoter-bearing template and trigger the extension. Then, the CRISPR guide RNA (crRNA) transcribed from the extended template activated the collateral DNase activity of Cas12a, releasing the fluorophore from the quenched DNA signal probe to report the FEN1 detection result. The high specificity for FEN1 was validated by comparing with other repair-relevant proteins. The limit of detection (LOD) could be as low as 0.03 mU, which is sensitive enough to detect the FEN1 activity in biological samples. In addition, the inhibition assay of FEN1 was also successfully achieved with this platform, proving its potential in inhibitor screening. In summary, this study provides a novel biosensor for FEN1 activity analysis and provides new insights into the development of CRISPR-based biosensors for non-nucleic acid targets.

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
The accurate, simple and sensitive detection of bacterial infections at the early stage is highly valuable in preventing the spread of disease. Recently, CRISPR-Cas12a enzyme-derived nucleic acid detection methods have emerged along with the discovery of the indiscriminate single-stranded DNA (ssDNA) cleavage activity of Cas12a. These nucleic acid detection methods are made effective and sensitive by combining them with isothermal amplification technologies. However, most of the proposed CRISPR-Cas12a strategies involve Cas-crRNA complexes in the preassembled mode, which result in inevitable nonspecific background signals. Besides, the signal ssDNA used in these strategies needs tedious pre-labeling of the signal molecules. Herein, a post-assembly CRISPR-Cas12a method has been proposed based on target-induced transcription amplification and real-time crRNA generation for bacterial 16S rDNA biosensing. This strategy is label-free through the combination of microchip electrophoresis (MCE) detection. In addition, this method eliminates the need for a protospacer adjacent motif (PAM) on the target sequences, and has the potential to be an effective and simple method for nucleic acid detection and infectious disease diagnosis.

Abstract
N6-methyladenosine modification as an mRNA modification in mammalian cells is dynamically reversible, regulated by RNA demethylase [e.g., fat mass and obesity-associated protein (FTO)]. The abnormal expression of FTO is closely related to numerous diseases (e.g., various cancers and obesity). Herein, we demonstrate the single-molecule counting of FTO in human cancer cells and breast tissues based on a T7 RNA polymerase-mediated rolling circle transcription (RCT) amplification-driven clustered regularly interspaced short palindromic repeat (CRISPR)─Cas12a. When FTO is present, it demethylates the DNA substrate, initiating the DpnII-mediated cleavage reaction. After magnetic separation, the cleaved DNA fragments trigger the T7 RNA polymerase-mediated RCT amplification, activating CRISPR-/Cas12a-mediated cleavage of signal probes and releasing abundant FAM molecules that are simply counted via single-molecule detection. In this assay, only target FTO can generate CRISPR RNAs, efficiently improving detection specificity. Moreover, the integration of single-molecule detection with magnetic separation achieves zero background and effectively enhances detection sensitivity. This method can specifically and sensitively monitor FTO activity with a limit of detection of 1.20 × 10-13 M, and it may measure FTO at the single-cell level. Furthermore, it may accurately discriminate the FTO expression level in breast tissues between healthy persons and breast cancer patients and screen the FTO inhibitors as well, with great potential in clinical diagnosis and drug discovery.

Abstract
Pathogen nucleic acid detection is of great significance to control the spread of diseases caused by the viruses. Nevertheless, traditional methods for nucleic acid detection such as polymerase chain reaction (PCR) and oligonucleotide microarrays require bulky instruments, which restrain their point-of-care (POC) testing application. Here, we proposed a POC method enabling sensitive detection of pathogen nucleic acids by combining the clustered regularly interspaced short palindromic repeat (CRISPR) Cas12a-based assay and personal glucometer readout (PGM). The quantification of target pathogen DNA by PGM was achieved based on pathogen DNA activates Cas12a ssDNase to cleave magnetic bead-DNA-invertase reporter probe, and separated free invertase to catalyze hydrolysis of sucrose to glucose. Without using nucleic acid amplification technology, we demonstrated here dual signal amplifications based on Cas12a and invertase-mediated catalytic reactions, making it possible to sensitively detect HIV-related DNA or SARS-CoV-2 pseudovirus with the limits of detection of 11.0 fM and 50 copies/μL, respectively. This strategy also showed excellent selectivity as well as potential applicability for detection of HIV in human serum samples or of SARS-CoV-2 in saliva samples. Therefore, our CRISPR-PGM-based dual signal amplifications detection platform might offer a great promise in POC diagnosis of pathogen nucleic acids.

Abstract
Here, we established a strategy (MPT-Cas12a/13a) that combined CRISPR/Cas12a and Cas13a for simultaneously detecting CaMV35S and T-nos based on multiplex PCR (M-PCR) and transcription. It realized a simultaneous detection mode with different signals in the same space. The MPT-Cas12a/13a had excellent sensitivity with the limit of detection as low as 11 copies of T-nos and 13 copies of CaMV35S and it had outstanding specificity and anti-interference ability in actual sample analysis. Therefore, it is a potential candidate in the detection of GM crops.

Abstract
The ligase chain reaction (LCR), as a classic nucleic acid amplification technique, is popular in the detection of DNA and RNA due to its simplicity, powerfulness, and high specificity. However, homogeneous and ultrasensitive LCR detection is still quite challenging. Herein, we integrate the LCR with a CRISPR-Cas12a system to greatly promote the application of the LCR in a homogeneous fashion. By employing microRNA as the model target, we design LCR probes with specific protospacer adjacent motif sequences and the guide RNA. Then, the LCR is initiated by target microRNA, and the LCR products specifically bind to the guide RNA to activate the Cas12a system, triggering secondary signal amplification to achieve ultrasensitive detection of microRNA without separation steps. Moreover, by virtue of a cationic conjugated polymer, microRNA can not only be visually detected by naked eyes but also be accurately quantified based on RGB ratio analysis of images with no need of sophisticated instruments. The method can quantify microRNA up to 4 orders of magnitude, and the determination limit is 0.4 aM, which is better than those of other reported studies using CRISPR-Cas12a and can be compared with that of the reverse-transcription polymerase chain reaction. This study demonstrates that the CRISPR-Cas12a system can greatly expand the application of the LCR for the homogeneous, ultrasensitive, and visual detection of microRNA, showing great potential in efficient nucleic acid detection and in vitro diagnosis.

Abstract
8-Oxoguanine DNA glycosylase is essential for maintaining genomic integrity and stability, while its abnormal activity may lead to the disturbance in the normal DNA damage repair and the occurrence of carcinogenicity and teratogenicity. Herein, we construct a CRISPR-Cas-based biosensor for rapid and sensitive measurement of 8-oxoguanine DNA glycosylases. This biosensor involves a hairpin probe and integrates quadratic strand displacement amplification (SDA) with a CRISPR/Cas12a effector with the characteristics of rapidity (within 40 min) and isothermal assay. The presence of 8-oxoguanine DNA glycosylase can initiate the quadratic SDA to produce large amounts of activators with the assistance of polynucleotide kinase (PNK). Subsequently, the activators can bind with crRNA to activate Cas12a, cleaving signal probes and recovering Cy5 fluorescence, which can be accurately quantified by single-molecule imaging. Notably, the designed hairpin probes can effectively block the hybridization of the generated activators with free hairpin probes, endowing this biosensor with high sensitivity. In addition, the utilization of PNK instead of apurinic/apyrimidinic endonuclease (APE1) greatly simplifies the experimental procedure to only a one-step reaction. The introduction of a single-molecule detection further reduces the sample consumption and improves the sensitivity. This biosensor displays a detection limit of 4.24 × 10-9 U μL-1, and it can accurately quantify cellular human 8-oxoguanine DNA glycosylase at a single-cell level. Furthermore, this biosensor can be applied for the screening of inhibitors, the analysis of kinetic parameters, and the discrimination of cancer cells from normal cells, with potential applications in molecular diagnostic and point-of-care testing.
