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.
本工作提出了一种基于引物交换反应（PER）的 SARS-CoV-2 RNA 检测的简单方法。通过巧妙地整合 PER 级联和 CRISPR/cas12a 系统，该方法可以在 40 分钟内方便地检测目标 RNA，并能区分目标序列中的单碱基突变，表现出优异的分析性能。
