荧光探针在氰化物分析中的研究进展

氰化物极易与细胞色素氧化酶键合，抑制电子转移、导致组织缺氧，从而显示较强的毒性。荧光化学传感器作为简易、灵敏且可视化的方法广泛应用于氰化物的检测。本文对荧光探针在氰化物检测中的应用进行综述，概述了氰化物的毒性机制和荧光探针对氰化物的响应机理。同时，本文总结了荧光探针在水体、食品和生物组织中对氰化物的检测及生物成像中的应用，并对荧光探针在结构设计中如何提高生物兼容性和靶向性等进行了展望，以期为光化学探针分子的设计及应用提供理论与研究依据。

Progress of fluorescent probe for cyanide analysis

Cyanide shows strong toxicity because it readily binds to the iron in cytochrome c oxidase, inhibiting electron transport and resulting in hypoxia. Fluorescent chemosensors are widely used in the detection of cyanide due to their simplicity, sensitivity, and visualization. In this paper, the applications of fluorescent probes in cyanide detection were reviewed and the toxicity mechanism of cyanide and the response mechanism of fluorescent probe to cyanide were summarized. Furthermore, we also summarized the applications of fluorescent probe for the detection and bioimaging of cyanide in water, food, and biological tissue. The prospect for improving the biological compatibility and targeting ability of the fluorescent probes in the structure design was also discussed, which would be respected to provide theoretical and research basis for the design and application of photochemical probe molecules.
