Conventional substrates for surface‐enhanced Raman spectroscopy (SERS) present some limitations. Plasmonic colloids are unstable in complex real samples and do not present hot spots. Conversely, engineered thin films are expensive and allow the study of a limited volume of sample. Hybrid platforms based in the adsorption of colloids on optically inert nano or microscaled materials put together the advantages of both classical methods for analysis. As the particles are densely packed, their assemblies present the same optical activities as the thin films, and because the inert template is usually colloidally stable, the assemblies behave as colloidal particles. This review focus on the different strategies proposed, up to date, to produce homogeneous nanoparticles (NPs) assemblies supported on colloidal templates for different applications.

在光学惰性模板上制备用于表面增强拉曼光谱的胶体平台

用于表面增强拉曼光谱（SERS）的常规基材存在一些局限性。等离子体胶体在复杂的真实样品中不稳定，不会出现热点。相反，工程化的薄膜价格昂贵，并且允许研究有限的样品量。基于胶体在光学惰性纳米或微米级材料上的吸附的混合平台汇集了两种经典分析方法的优点。由于粒子密集地堆积，它们的组件具有与薄膜相同的光学活性，并且由于惰性模板通常是胶体稳定的，因此组件的行为就像胶体颗粒一样。这篇综述集中在最新提出的不同策略上，以产生支持在胶体模板上用于不同应用的均质纳米粒子（NP）组件。
