Abstract
MicroRNA (miRNA) represents a class of important potential biomarkers, and their intracellular imaging is extremely useful for fundamental research and early diagnosis of human cancers. Hybridization chain reaction (HCR) has been shown to be effective in detecting miRNA in living cells. However, its practical applications are still hampered by inefficient reaction kinetics and poor biological stability under complex intracellular conditions. To address these issues, we report a palindrome-mediated multiple hybridization chain reaction (P-HCR) system to better visualize intracellular miRNAs. In the presence of the target miRNA, a layered nanosheet DNA architecture (LSDA) can be assembled in situ via the palindrome-mediated multiple HCR process. We demonstrate that the biological stability of this reaction system could be significantly improved by designing the probes to dumbbell-shaped structures and the distance of hairpins was effectively decreased due to palindrome-chained effect. Consequently, miRNA can be quantitatively identified even at extremely low concentrations of 4.7 pM. The P-HCR system can effectively differentiate the expression levels of miRNA in different tumor cells and normal cells, as demonstrated in live cell tests and the results were in agreement with the PCR, which is considered the gold standard. The new (P-HCR) system has the potential to revolutionize miRNA imaging in living cells.

Abstract
This article presents a review of recent advancements in the utilization of NAA-based techniques for detecting foodborne pathogens in food products, focusing on studies conducted within the past five years. This review revealed that recent research efforts have primarily aimed at enhancing sensitivity and specificity by improving sample pre-treatment/preparation, DNA isolation, and readout methods. Isothermal-based amplification methods, such as LAMP, RPA, RAA, and RCA, have emerged as promising approaches, providing rapid results within one h and often demonstrating comparable or superior sensitivity to conventional or qPCR methods. However, the attention paid to specific pathogens varies, with Salmonella spp., Listeria spp., E. coli, and V. parahaemolyticus receiving more focus than norovirus and other similar pathogens. NAA-based methods have the potential to significantly contribute to food safety and public health protection. However, further advancements are necessary to fully realize their benefits.

Abstract
Loop-mediated isothermal amplification (LAMP), a rapid and sensitive isothermal nucleic acid amplification method, is a promising alternative to other molecular amplification techniques due to its superior specificity and sensitivity. However, due to primer dimerization, LAMP results in nonspecific and nontemplate amplification. And during the amplification confirmation process, there is carry-over contamination. These factors can result in false-positive results that overestimate the amount of DNA, preventing accurate detection. This review outlined several techniques for reducing false-positive LAMP results before amplification and confirming false-positive results after amplification. Before the amplification step, DNA polymerase activity can be decreased with organic additives such as dimethyl sulfoxide, betaine, and pullulan to prevent nonspecific amplification. The enzyme uracil-DNA-glycosylase (UDG) can eliminate false-positive results caused by carry-over contamination, and the hot-start effect with gold nanoparticles can reduce nonspecific amplification. When confirming false-positive results using clustered regularly interspaced short palindromic repeats, guide RNA accurately detects LAMP amplification, allowing differentiation from nonspecific amplification. By confirming amplification, the colorimetric change in the deoxyribozyme (DNAzyme) formed by the reaction of the G-quadruplex sequence of the LAMP amplicon and hemin can distinguish false-positive results. Lateral flow immunoassay can distinguish false-positive results by accurately recognizing hybridized probes to LAMP amplicons.

Abstract
Visualized gene detection based on the CRISPR-Cas12/CRISPR-Cas13 technology and lateral flow assay device (CRISPR-LFA) has shown great potential in point-of-care testing sector. Current CRISPR-LFA methodology mainly utilizes conventional immuno-based LFA test strips, which could visualize whether the reporter probe is trans-cleaved by Cas protein, indicating the target positive detection. However, conventional CRISPR-LFA usually produces false-positive results in target negative assay. Herein, a nucleic acid Chain Hybridization-based Lateral Flow Assay platform, named CHLFA, has been developed to achieve the CRISPR-CHLFA concept. Different from the conventional CRISPR-LFA, the proposed CRISPR-CHLFA system was established based on the nucleic acid hybridization between the GNP-probe embedded in test strips and ssDNA (or ssRNA) reporter from CRISPR (LbaCas12a or LbuCas13a) reaction, which eliminated the requirement of immunoreaction in conventional immuno-based LFA. The assay realized the detection of 1-10 copy of target gene per reaction within 50 min. The CRISPR-CHLFA system achieved highly accurate visual detection of target negative samples, thus overcoming the false-positive problem that often produced in assays using conventional CRISPR-LFA. The CRISPR-CHLFA platform was further adopted for the visual detection of marker gene from SASR-CoV-2 Omicron variant and Mycobacterium tuberculosis (MTB), respectively, and 100% accuracy for the analysis of clinical specimens (45 SASR-CoV-2 specimens and 20 MTB specimens) was obtained. The proposed CRISPR-CHLFA system could provide an alternative platform for the development of POCT biosensors and can be widely adopted in accurate and visualized gene detection.

Abstract
The combination of clustered regularly interspaced short palindromic repeats (CRISPR) and its associated Cas protein is an effective gene-editing instrument. Among them, the CRISPR-Cas12a system forms a DNA-cleavage-capable complex with crRNA and exerts its trans-cleavage activity by recognising the PAM site on the target pathogen's gene. After amplifying the pathogenic gene, display materials such as fluorescent probes are added to the detection system, along with the advantages of rapid detection and high sensitivity of the CRISPR system, so that pathogenic bacteria can be diagnosed with greater speed and precision. This article reviews the mechanism of CRISPR-Cas12a in rapid detection, as well as its progress in the rapid detection of pathogenic bacteria in conjunction with various molecular biology techniques, in order to provide a foundation for the future development of a more effective detection platform.
