光电化学（PEC）传感是一种将PEC过程与目标物识别反应相结合的新型传感技术，在分析检测领域得到了快速发展。PEC具有光激发-电检测的特点，其传感具有背景信号低和灵敏度高等优点。目前，常见的PEC传感检测模式主要分为信号增强型和信号减弱型，两者均依赖单个输出信号的变化。在这两种模式下，当被测体系存在氧化还原干扰物时，将导致光电流增加或减小，不可避免地会产生假阳性或假阴性结果。相较而言，基于信号极性翻转的PEC传感在识别目标物后能够输出两种极性不同的光电流信号，而非仅增加或减小光电流信号，因此，该传感策略能够有效提高检测过程的抗干扰能力和准确度。本文综述了常见的...

Photoelectrochemical (PEC) sensing, as a new sensing technology that combines PEC process and target recognition reactions, has been rapidly developed in the field of analysis. Based on its characteristics of photoexcitation-electrical detection, PEC sensing has attracted great attention due to its advantages such as low background signal, high sensitivity and so on. At present, common PEC sensing detection modes are mainly divided into signal-off and signal-on modes, but both modes depend on the change of a single output signal. The presence of possible redox-active interferents in the actual...
