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.
规律间隔成簇短回文重复序列（CRISPR）/CRISPR相关蛋白（Cas）系统存在于大多数细菌与所有的古生菌中，用于抵御外源性遗传物质的入侵，是自我防御的重要手段。CRISPR/Cas技术作为一种简便、快速、灵敏、特异的检测工具，被广泛应用于农业、工业、牧业以及医学等领域。本文主要对CRISPR/Cas系统与荧光、可视化及表面增强拉曼光谱等检测技术相结合的生物传感器的应用现状、优势和局限性以及未来的发展方向进行阐述。.
