Abstract：
The identification and detection of pesticides is crucial to protecting both the environment and human health. However, it can be challenging to conveniently and rapidly differentiate between different types of pesticides. We developed a supramolecular fluorescent sensor array, in which calixarenes with broad-spectrum encapsulation capacity served as recognition receptors. The sensor array exhibits distinct fluorescence change patterns for seven tested pesticides, encompassing herbicides, insecticides, and fungicides. With a reaction time of just three minutes, the sensor array proves to be a rapid and efficient tool for the discrimination of pesticides. Furthermore, this supramolecular sensing approach can be easily extended to enable real-time and on-site visual detection of varying concentrations of imazalil using a smartphone with a color scanning application. This work not only provides a simple and effective method for pesticide identification and quantification, but also offers a versatile and advantageous platform for the recognition of other analytes in relevant fields.
摘要：
农药的鉴定和检测对于保护环境和人类健康至关重要。然而,方便和快速地区分不同类型的农药可能是具有挑战性的。我们开发了一种超分子荧光传感器阵列，其中具有广谱包封能力的杯芳烃用作识别受体。传感器阵列对七种测试的农药表现出不同的荧光变化模式，包括除草剂，杀虫剂,和杀菌剂。反应时间只有三分钟，传感器阵列被证明是一种快速有效的农药鉴别工具。此外，这种超分子传感方法可以很容易地扩展,以便使用带有彩色扫描应用程序的智能手机实时和现场视觉检测不同浓度的伊玛唑。这项工作不仅为农药鉴定和定量提供了一种简单有效的方法,但也为识别相关领域的其他分析物提供了通用且有利的平台。
