Abstract

Poisoning of agricultural products through the use of pesticides has created a high risk to the environment and human health. In recent years, substantial research has been devoted to replacing harmful chemical pesticides with naturally derived organic compounds and the safer detection of pernicious pesticide residues by selective and sensitive methods using suitable sensor systems has also been given equal priority. Among various sensing methods that are currently available, fluorescence-based sensing has acquired widespread acceptance and become a feasible technique for the trace analysis of pesticide residues due to several practical advantages. In this review article, we provide a systematic overview of the recent progress made in using fluorescence-based chemosensing of different classes of pesticides and their success in real-world applications. Various fluorescence chemosensors highlighted in this article are categorized based on their sensing propensity for a particular class of pesticides. In the initial section of the article, we have highlighted a detailed discussion on the classification of pesticides, and various methods available for pesticide detection, and the later sections report various chemosensors reported to date for sensing different classes of pesticides. Finally, we put forward a short discussion on the advantages and existing practical difficulties in employing fluorescent chemosensors for pesticide detection and also state the future perspective of this field toward developing practically useful sensing systems.

基于荧光的农药化学传感研究进展
农药对农产品的毒害给环境和人类健康带来了很大的风险。近年来,大量研究致力于用天然衍生的有机化合物取代有害化学农药,使用合适的传感器系统通过选择性和敏感的方法更安全地检测有害农药残留也得到了同样的重视。在现有的各种传感方法中,基于荧光的传感由于具有一些实际的优点,已经得到了广泛的接受,并成为一种可行的农药残留痕量分析技术。在这篇综述文章中,我们提供了最近的进展,利用荧光化学传感不同类别的农药及其成功的实际应用系统的概述。本文重点介绍的各种荧光化学传感器是根据它们对特定种类农药的传感倾向进行分类的。在文章的开头部分,我们重点介绍了对农药分类的详细讨论,以及用于农药检测的各种方法,后面的部分报告了迄今为止报道的用于检测不同类别农药的各种化学传感器。最后,对荧光化学传感器用于农药检测的优势和存在的实际困难进行了简要的讨论,并展望了该领域未来的发展方向,以开发实用的传感系统。
