Pesticides have an important role in rising the overall productivity and yield of agricultural foods by eliminating and controlling insects, pests, fungi, and various plant-related illnesses. However, the overuse of pesticides has caused pesticide pollution of water bodies and food products, along with disruption of environmental and ecological systems. In this regard, developing low-cost, simple, and rapid-detecting approaches for the accurate, rapid, efficient, and on-site screening of pesticide residues is an ongoing challenge. Electrochemiluminescence (ECL) possesses the benefits of great sensitivity, the capability to resolve several analytes using different emission wavelengths or redox potentials, and excellent control over the light radiation in time and space, making it a powerful strategy for sensing various pesticides. Cost-effective and simple ECL systems allow sensitive, selective, and accurate quantification of pesticides in agricultural fields. Particularly, the development and progress of nanomaterials, aptamer/antibody recognition, electric/photo-sensing, and their integration with electrochemiluminescence sensing technology has presented the hopeful potential in reporting the residual amounts of pesticides. Current trends in the application of nanoparticles are debated, with an emphasis on sensor substrates using aptamer, antibodies, enzymes, and molecularly imprinted polymers (MIPs). Different strategies are enclosed in labeled and label-free sensing along with luminescence determination approaches (signal-off, signal-on, and signal-switch modes). Finally, the recent challenges and upcoming prospects in this ground are also put forward.
农药在消除和控制昆虫、害虫、真菌以及各种与植物有关的疾病方面,对提高农业食品的整体生产力和产量起着重要作用。然而,农药的过度使用导致了水体和食品中农药的污染,以及环境和生态系统的破坏。在这方面,开发低成本、简单、快速检测方法,以准确、快速、高效、现场筛选农药残留,是一个持续的挑战。电致化学发光(ECL)具有灵敏度高、能够使用不同的发射波长或氧化还原电位来解析多种分析物、以及对光辐射进行时间和空间的精确控制等优点,是一种用于检测各种农药的强大策略。具有成本效益和简单的 ECL 系统允许在农业领域中对农药进行灵敏、选择性和准确的定量。特别是,纳米材料的开发和进展、适体/抗体识别、电/光传感及其与电致化学发光传感技术的结合,为报告农药残留量提供了有希望的潜力。目前,正在讨论纳米颗粒应用的趋势,重点是使用适体、抗体、酶和分子印迹聚合物(MIPs)的传感器基底。不同的策略包括标记和无标记传感以及发光测定方法(信号关闭、信号开启和信号切换模式)。最后,还提出了该领域目前的挑战和未来的前景。
