Abstract

Ratiometric photoelectrochemical (PEC) sensors have emerged as a compelling class of analytical tools, offering internal calibration, enhanced signal stability, and improved tolerance to environmental variability. These advantages are particularly relevant to the field of food analysis, where sample complexity often compromises the reliability of single-signal detection strategies. In recent years, diverse ratiometric PEC platforms have been developed. This review systematically categorizes ratiometric PEC sensors into five main types: wavelength-resolved, voltage-resolved, spatially resolved, dual-mode, and other emerging strategies involving polarity switching or stimulus-responsive interfaces. For each category, representative sensing mechanisms, photoelectrode architectures, and real-world applications-especially in the detection of food contaminants such as mycotoxins, antibiotics, and pesticide residues-are comprehensively discussed. Furthermore, key challenges and future directions are outlined. This review aims to provide a conceptual foundation and technical reference for advancing ratiometric PEC sensing technologies in food safety and beyond.

比率光电化学传感器：食品分析的进展和新兴应用。

比率光电化学（PEC）传感器已经成为一种引人注目的分析工具，提供内部校准，增强信号稳定性，提高对环境变化的耐受性。这些优势与食品分析领域特别相关，其中样品复杂性通常会损害单信号检测策略的可靠性。近年来，人们开发了各种比率型PEC平台。本文系统地将比率型PEC传感器分为五种主要类型：波长分辨型、电压分辨型、空间分辨型、双模型和其他涉及极性切换或刺激响应接口的新兴策略。对于每个类别，具有代表性的传感机制，光电极结构和实际应用-特别是在检测食品污染物，如真菌毒素，抗生素和农药残留-进行了全面讨论。此外，还概述了主要挑战和未来方向。本文综述的目的是为在食品安全及其他领域推进比例电位传感技术提供概念基础和技术参考。
