摘要:表面增强拉曼光谱(SERS)是基于探针分子的指纹信息(分子振动、转动信息等),可应用于具有灵敏
度和特异性分子结构研究的分析技术。SERS 借助具有优异的等离子体性能的贵金属纳米材料作为基底,可对单
组分或复杂多组分的痕量农药残留物进行分析检测。其中,柔性 SERS 基底具有孔隙率高、制备成本低、柔韧
可折叠弯曲等特点,在复杂样品体系中提取、过滤、浓缩探针分子等应用中具有刚性 SERS 基底不可比拟的优
势。柔性 SERS 基底主要是由基于生物基材料、聚合物和碳材料的 3 类材料来支撑和固定修饰表面提供光谱增
强作用的贵金属纳米材料。重点综述了这 3 种类型的柔性 SERS 基底常用制备方法及应用,充分利用 SERS 的
“指纹图谱”分析优势,介绍了柔性 SERS 基底应用于不同农药残留的最新研究进展。最后,对 SERS 技术发展
和应用提出了亟待解决的问题。

Abstract: Surface-enhanced Raman spectroscopy (SERS) is a sensitive and specific analytical technology
based on the fingerprint information of probe molecules (molecular vibration, rotation information, etc).
With the help of precious metal nanomaterials with excellent plasma properties, SERS can be used for the
analysis and detection of single-component or complex multi-component trace pesticide residues. Among
them, flexible SERS substrate has the characteristics of high porosity, low preparation cost, flexibility,
folding and bending, etc. It has incomparable advantages over rigid SERS substrates in the extraction,
filtration and concentration of probe molecules in complex sample systems. Flexible SERS substrates are
mainly based on biobased materials, polymer and carbon materials to support and fix the modified surface
to provide spectral enhancement of precious metal nanomaterials. The common preparation methods and
applications of these three types of flexible SERS substrates are reviewed. The latest research progress in
the application of flexible SERS substrates to different pesticide residues is introduced by making full use
of the advantages of “fingerprint” of SERS. Finally, the problems to be solved urgently for the development
and application of SERS technology are put forward.
