Mycotoxins, highly toxic secondary metabolites of fungus, have brought considerable threats to human health. It is of great significance to develop low-cost, rapid and efficient analytical methods for monitoring mycotoxins in foodstuffs. Photoelectrochemical (PEC) biosensors have been promising tools for mycotoxin detection thanks to their superior properties. Photoactive materials play important roles in the biosensing systems as transducer converting chemical information into detectable PEC signal. Signal strategies based on specific recognition elements also affects a lot on the analytical performance of PEC biosensors. This paper provides a comprehensive review on photoactive materials and signal strategies used in the PEC biosensors for mycotoxin monitoring. The future prospects in this field are also discussed.

真菌毒素，一种剧毒的真菌次生代谢产物，已对人类健康构成了巨大威胁。开发低成本，快速和有效的分析方法来监测食品中的霉菌毒素具有重要意义。光电化学（PEC）生物传感器由于其优越的性能而成为霉菌毒素检测的有前途的工具。光敏材料在生物传感系统中起着重要作用，因为传感器将化学信息转换为可检测的PEC信号。基于特定识别元素的信号策略也会对PEC生物传感器的分析性能产生很大影响。本文提供了对PEC生物传感器中用于霉菌毒素监测的光敏材料和信号策略的全面综述。还讨论了该领域的未来前景。
