The establishment of rapid and efficient contamination detection methods in agricultural fields is of great significance for safeguarding agricultural production and human health, and for ensuring the healthy development of agricultural industries. As a booming analytical method, photoelectrochemical (PEC) sensors, which combine the advantages of electrochemical analysis and optical analysis, have received increasing research attention. Due to the complete separation of the excitation source (light) and the detection signal (current), the background signal of PEC sensors is greatly decreased, and their sensitivity is high. This review aims to cover the advances in PEC sensors for contamination analysis in agricultural fields over the past 5 years, including the analysis of heavy metals, antibiotics, pesticides, and toxins. The future prospects in this field are also discussed.
在农业领域建立快速高效的污染检测方法对于保障农业生产和人类健康，以及确保农业产业的健康发展具有重要意义。作为一种蓬勃发展的分析方法，光电化学（PEC）传感器结合了电化学分析和光学分析的优势，受到了越来越多的研究关注。由于激发源（光）和检测信号（电流）的完全分离，PEC 传感器的背景信号大大降低，其灵敏度很高。本综述旨在涵盖过去 5 年中用于农业领域污染分析的 PEC 传感器的进展，包括对重金属、抗生素、农药和毒素的分析。还讨论了该领域的未来前景。
