Abstract

Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems are becoming powerful tools for disease biomarkers detection. Due to the specific recognition, cis-cleavage and nonspecific trans-cleavage capabilities, CRISPR/Cas systems have implemented the detection of nucleic acid targets (DNA and RNA) as well as non-nucleic acid targets (e.g., proteins, exosomes, cells, and small molecules). In this review, we first summarize the principles and characteristics of various CRISPR/Cas systems, including CRISPR/Cas9, Cas12, Cas13 and Cas14 systems. Then, various types of applications of CRISPR/Cas systems used in detecting nucleic and non-nucleic acid targets are introduced emphatically. Finally, the prospects and challenges of their applications in biosensing are discussed.
