Application of CRISPR/Cas-based biosensors for detecting nucleic acid of pathogens

摘要:

成簇规律间隔短回文重复序列/成簇规律间隔短回文重复序列相关蛋白 (Clustered regularly interspaced short palindromic repeats/CRISPR-associated protein，CRISPR/Cas) 因高效的靶向结合和可编程性，已被开发为一种精准、高效、低价和高灵敏度的核酸检测工具。目前基于CRISPR-Cas体系的生物传感器在病原体核酸检测方面显示出了优良的性能，受到了人们的广泛关注，这种新型的病原体核酸检测有望替代传统的病原体检测方法。文中就基于CRISPR/Cas体系的生物传感器在病原体核酸检测中的最新研究进展进行综述。

Abstract:

Clustered regularly interspaced short palindromic repeats/clustered regularly interspaced short palindromic repeats -associated protein (CRISPR/Cas) has been developed as a precise, efficient, affordable and sensitive nucleic acid detection tool due to its efficient targeted binding ability and programmability. At present, biosensors based on CRISPR-Cas system have shown excellent performance in the detection of nucleic acid of pathogens, which has attracted widespread attention, and is expected to replace the conventional detection methods. This review summarizes the latest research progress of biosensors based on CRISPR/Cas system for detecting nucleic acid of pathogens.
