A simple method is proposed in this work for the detection of SARS-CoV-2 RNA based on a primer exchange reaction (PER). By ingeniously integrating the PER cascade and CRISPR/cas12a system, this method can achieve convenient detection of the target RNA in 40 min and distinguish a single-base mutation from the target sequence, demonstrating its superior analytical performance.
