Research progress of CRISPR/Cas biosensors based on different signal amplification strategies / 中华预防医学杂志

CRISPR/Cas(the clustered regularly interspaced short palindromic repeats-CRISPR associated)system exists in most bacteria and all archaea. It is an important strategy for bacteria and archaea to resist foreign nucleic acid invasion and use for self-defense. The CRISPR/Cas system is a simple, fast, and specific diagnostic tool, which is widely used in agriculture, industry, animal husbandry, and medicine. This article mainly introduces and discusses recently advantages and limitations of biosensors combining CRISPR/Cas system with fluorescence, visualization and surface enhanced raman related technologies, as well as future research directions.
