生物传感器用于农药残留检测的研究进展：现状,挑战及未来展望

摘要

Public concerns over pesticide residues in food had been increasing because of their bioaccumulation effects and their great danger to the environments and human’s heath. It was therefore imperative to detect the pesticide residue using all available analytical methods, especially highly sensitive, simple, rapid and low cost. The biosensor detection strategies held a great promise for the detection of agricultural pesticides, attributing to their key features such as high sensitivity, fast response, robustness, low cost, and miniaturization. This paper reviewed the advances in the design and fabrication of biosensor for pesticide detection and their applications in the food and environment safety. Both advantages and drawbacks of these techniques were summarized. Finally, challenges and perspectives in further developing pesticide biosensors were also discussed.%　　食品中农药残留在人体中的生物累积效应和农药对环境和人类健康所造成的危害逐渐受到人们的重视，发展高灵敏度、高选择性、简单快速、成本低廉的残留农药检测分析方法势在必行。生物传感器由于具有灵敏度高、简便、快速、成本低廉等优点而成为一种理想的农药检测手段。本文综述了近年来农药残留生物传感器的设计原理及其在食品和环境安全中的应用方面的研究进展，总结了不同农药残留生物传感器的优缺点及其所面临的挑战和前景展望。
