Pesticides are a family of non-biodegradable chemical compounds which widely used in agriculture to control pests and increase yield production. However, overuse or abuse of pesticides and their metabolites may cause potential toxicity for the environment as well as human health and all other living organisms, even at deficient concentrations. Consequently, the development of sensors for monitoring these compounds is significant. Recently, nanoparticles-based sensors have been extensively employed as a potential alternative or complementary analytical tool to conventional detection methods for pesticides. Among them, gold nanoparticles (AuNPs) owing to their unique optical properties have been developed as smart sensors with high selectivity, sensitivity, simplicity, and portability. These comprehensive reviews have summarized various studies performed based on different detection strategies, i.e., colorimetric, fluorescence, surface-enhanced Raman scattering, and electrochemical, using AuNPs as sensing probes for pesticide analysis in various matrices. Additionally, the current challenges and future trends for developing novel AuNPs-based sensors for the detection of pesticides are also discussed.
农药是一类不可生物降解的化合物，广泛用于农业以控制害虫并提高产量。然而，即使在浓度不足的情况下，过度使用或滥用农药及其代谢物也可能对环境、人类健康以及所有其他生物造成潜在毒性。因此，开发用于监测这些化合物的传感器具有重要意义。近年来，基于纳米颗粒的传感器已被广泛用作传统农药检测方法的潜在替代或补充分析工具。其中，金纳米颗粒（AuNPs）因其独特的光学性质，已被开发成为具有高选择性、灵敏度、简便性和便携性的智能传感器。这些综述总结了基于不同检测策略（即比色法、荧光法、表面增强拉曼散射法和电化学法）进行的各种研究，这些研究使用金纳米颗粒作为传感探针，用于分析各种基质中的农药。此外，还讨论了开发用于检测农药的新型基于金纳米颗粒的传感器目前面临的挑战和未来趋势。
