This review focuses on recent developments in hybrid and nanostructured substrates for SERS (surface-enhanced Raman scattering) studies. Thus substrates composed of at least two distinct types of materials, in which one is a SERS active metal, are considered here aiming at their use as platforms for chemical detection in a variety of contexts. Fundamental aspects related to the SERS effect and plasmonic behaviour of nanometals are briefly introduced. The materials described include polymer nanocomposites containing metal nanoparticles and coupled inorganic nanophases. Chemical approaches to tailor the morphological features of these substrates in order to get high SERS activity are reviewed. Finally, some perspectives for practical applications in the context of chemical detection of analytes using such hybrid platforms are presented.
本综述重点介绍了用于 SERS（表面增强拉曼散射）研究的混合和纳米结构基底的最新进展。因此，这里考虑的是由至少两种不同类型的材料组成的基底，其中一种是 SERS 活性金属，旨在将其用作各种情况下化学检测的平台。简要介绍了与 SERS 效应和纳米金属的等离子体行为相关的基本方面。所描述的材料包括含有金属纳米粒子和耦合无机纳米相的聚合物纳米复合材料。综述了化学方法来调整这些基底的形态特征以获得高 SERS 活性。最后，提出了在使用此类混合平台进行化学分析物检测的背景下实际应用的一些展望。
