The enzymatic electrochemical biosensor has the advantages of simple operation, speed, and integration in the detection of organophosphorus pesticide (OPs) residues. It has the potential to become the best alternative to the traditional OP detection technology. This article introduces the OP identification principle of different enzymes, the OP detection mechanism of several common sensors, and the enzyme assembly method. In addition, the article discusses application of nanomaterials in sensor preparation and sensor performance parameters in the past decade. The related content of early sensors is outside the scope of this article.
酶电化学生物传感器在有机磷农药（OPs）残留检测方面具有操作简单、快速、集成化等优点，有望成为传统 OP 检测技术的最佳替代品。本文介绍了不同酶的 OP 识别原理、几种常见传感器的 OP 检测机制以及酶的组装方法。此外，还讨论了纳米材料在传感器制备中的应用以及过去十年中传感器的性能参数。早期传感器的相关内容不在本文的讨论范围之内。
