The integration of CRISPR/Cas and Argonaute with lateral flow strips offers a promising, easy-to-use, and portable method for on-site pathogen detection.
Pathogens contamination is a pressing global public issue that has garnered significant attention worldwide, especially in light of recent outbreaks of foodborne illnesses. Programmable nucleases like CRISPR/Cas and Argonaute hold promise as tools for nucleic acid testing owning to programmability and the precise target sequence specificity, which has been utilized for the development pathogens detection. At present, fluorescence, as the main signal output method, provides a simple response mode for sensing analysis. However, the dependence of fluorescence output on large instruments and correct analysis of output data limited its use in remote areas. Lateral flow strips (LFS), emerging as a novel flexible substrate, offer a plethora of advantages, encompassing easy-to-use, rapidity, visualization, low-cost, portability, etc. The integration of CRISPR/Cas and Argonaute with LFS, lateral flow assay (LFA), rendered a new and on-site mode for pathogens detection. In the review, we introduced two programmable nucleases CRISPR/Cas and Argonaute, followed by the structure, principle and advantages of LFA. Then diversified engineering detection pattens for viruses, bacteria, parasites, and fungi based on CRISPR/Cas and Argonaute were introduced and summarized. Finally, the challenge and perspectives involved in on-site diagnostic assays were discussed.
Li et al. (Mon,) conducted a review in Pathogen detection. CRISPR/Cas and Argonaute-powered lateral flow assay was evaluated. The integration of CRISPR/Cas and Argonaute with lateral flow strips provides a novel, on-site, and easy-to-use mode for the detection of viruses, bacteria, parasites, and fungi.
