Improved Strategies for CRISPR-Cas12-based Nucleic Acids Detection

Abstract

The COVID-19 pandemic has brought great challenges to traditional nucleic acid detection technology. Thus, it is urgent to develop a more simple and efficient nucleic acid detection technology. CRISPR-Cas12 has signal amplification ability, high sensitivity and high nucleic acid recognition specificity, so it is considered as a nucleic acid detection tool with broad development prospects and high application value. This review paper discusses recent advances in CRISPR-Cas12-based nucleic acid detection, with an emphasis on the new research methods and means to improve the nucleic acid detection capability of CRISPR-Cas12. Strategies for improving sensitivity, optimization of integrated detection, development of simplified detection mode and improvement of quantitative detection capabilities are included. Finally, the future development of CRISPR-Cas12-based nucleic acids detection is prospected.
