中文摘要: 从复杂和恶劣环境中有效地提取分析物对于促进表面增强拉曼散射(SERS)技术的实际应用具有重要意义。本文利用商业胶带的柔性、透明和粘接特性和Al2O3包裹的银纳米棒阵列的表面增强拉曼散射性能,提出了一种概念证明策略,用于农药残留的快速检测。胶带能够快速将分析物转移到表面增强拉曼谱仪衬底上,新型胶带表面增强拉曼谱仪是由一个简单的“粘贴,剥离,再次粘贴”的过程构成。易获取且能清楚区分表面增强拉曼散射信号的性能确保我们能够准确识别复杂分析物的成分,例如果蔬中的四甲基秋兰姆二硫醚和噻苯咪唑农药,该方法可应用于实际食品安全、环境监测和工业生产的过程控制。
外文摘要:The efficient extraction of analytes from complex and severe environments is significant for promoting the surface-enhanced Raman scattering (SERS) technique to actual applications. In this paper, a proof-of-concept strategy is proposed for the rapid detection of pesticide residues by utilizing the flexible, transparent, and adhesive properties of commercial tapes and SERS performance of Al2O3-coated silver nanorod (AgNR@Al2O3) arrays. The function of tapes is to rapidly transfer the analytes from the actual surface to the SERS substrate. The novel "tape-wrapped SERS (T-SERS)" approach was constructed by a simple "paste, peel off, and paste again" procedure. The easily obtained but clearly distinguished SERS signals allow us to quickly determine the constituents of complex surfaces, such as tetramethylthiuram disulfide and thiabendazole pesticides from fruits and vegetables, which may be practically applied to food safety, environmental monitoring, and industrial production process controlling.
