Abstract
Rapid and accurate molecular diagnostics are crucial for disease diagnosis and precision medicine. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR-associated (Cas) proteins have emerged as highly effective tools for molecular diagnostics. Numerous nucleic acid detection instruments and biosensors utilizing the CRISPR/Cas system have been developed. The profiling activity of CRISPR/Cas effectors has facilitated the creation of instrument-free, sensitive, precise, and rapid nucleic acid diagnostics. This review summarizes recent advancements in CRISPR technology for RNA detection, focusing on the application of Cas12 and Cas13 systems in two scenarios: in combination with isothermal amplification technology and without amplification. It also explores the significant potential of CRISPR as a next-generation technology for RNA detection and anticipates future developments. The ongoing advancements in CRISPR are expected to enhance precision and convenience in RNA testing, impacting both biomedical research and public health practices.
