The efficient extraction of targets from complex surfaces is vital for technological applications ranging from environmental pollutant monitoring to analysis of explosive traces and pesticide residues. In our present study, we proposed a proof-of-concept surface enhance Raman scattering (SERS) active substrate serving directly to the rapid extraction and detection of target molecules. The novel substrate was constructed by decorating the commercial tape with colloidal gold nanoparticles (Au NPs), which simultaneously provides SERS activity and “sticky” of adhesive. The utility of SERS tape was demonstrated by directly extracting pesticide residues in fruits and vegetables via a simple and viable “paste and peel off” approach. The obtained strong and easily distinguishable SERS signals allow us to detect various pesticide residues such as parathion-methyl, thiram, and chlorpyrifos in the real samples with complex surfaces including green vegetable, cucumber, orange, and apple.

柔性和粘性表面增强拉曼散射活性带，可快速检测水果和蔬菜中的农药残留

从复杂表面有效地提取目标物对于从环境污染物监测到爆炸痕迹和农药残留分析等技术应用而言至关重要。在我们目前的研究中，我们提出了一种概念验证的表面增强拉曼散射（SERS）活性底物，直接用于快速提取和检测目标分子。通过用胶体金纳米颗粒（Au NPs）装饰商业胶带来构造新型基材，该胶体同时提供SERS活性和粘合剂的“粘性”。通过简单，可行的“粘贴和剥离”方法直接提取水果和蔬菜中的农药残留，证明了SERS胶带的实用性。
