Abstract

A SERS substrate FP/Ag/ZIF-8 composed of filter paper (FP), silver nanoparticles (AgNPs) and zeolitic imidazolate framework (ZIF-8) film arranged in a layered structure was developed for sensitive detection of pesticide thiram in various samples. Roles of these components in analyte adsorption and Raman signal enhancement were studied using a pesticide intermediate 4-Aminothiophenol (4-ATP) as the probe. The substrate showed high adsorption and optimized SERS response with thick metal organic framework (MOF) coating (125 nm), which is different from previous reported plasmonic particle-MOF composite substrate, where thinnest MOF coating produced the strongest SERS signal. Detection limit for 4-ATP improved 1000-fold on FP/Ag/ZIF-8 (3 pM) compared with that on FP/Ag (3 nM). Importantly, the FP/Ag/ZIF-8 with porous and flexible property can efficiently capture pesticide thiram in different real samples using soaking, filtration or swabbing operation. The subsequent SERS detection of thiram showed advantages of low detection limit (soaking, LOD: 0.04 nM in lake water), fast detection (filtration, within 1 min in peach juice) and suitable for curve surface analysis (swabbing, LOD: 0.1 ng/cm on apple peel), respectively. The substrate also displayed good reproducibility, high stability and size-selective response for thiram detection. Such a layered plasmonic particle/MOF hybrid may hold great promise for toxicant analysis in environment and food.

摘要

一种由滤纸 (FP)、银纳米粒子 (AgNPs) 和沸石咪唑酯骨架 (ZIF-8) 薄膜组成的 SERS 基底 FP/Ag/ZIF-8 被开发用于在各种样品中灵敏检测农药福美双。使用农药中间体 4-氨基噻吩 (4-ATP) 作为探针研究了这些成分在分析物吸附和拉曼信号增强中的作用。该基底具有高吸附性和优化的 SERS 响应,具有较厚的金属有机骨架 (MOF) 涂层 (125nm),这与以前报道的等离子体粒子-MOF 复合基底不同,在以前的基底中,最薄的 MOF 涂层产生最强的 SERS 信号。与 FP/Ag(3nM)相比,FP/Ag/ZIF-8 对 4-ATP 的检测限提高了 1000 倍(3pM)。重要的是,具有多孔和柔性的 FP/Ag/ZIF-8 可以通过浸泡、过滤或擦拭操作有效地从不同的实际样品中捕获农药福美双。随后对福美双的 SERS 检测显示出低检测限的优势(浸泡,在湖水的 LOD:0.04nM)、快速检测(过滤,在桃汁中 1 分钟内)和适合曲面分析(擦拭,在苹果皮上的 LOD:0.1ng/cm)。该基底还表现出良好的重现性、高稳定性和对福美双检测的尺寸选择性响应。这种分层等离子体粒子/MOF 杂化材料可能在环境和食品中毒素分析方面具有广阔的应用前景。
