摘要: 基于金属包裹的多孔硅衬底具有制备成本低、检测能力强的优点。自20世纪表面增强拉曼散射(SERS)现象被发现以来,多孔硅-Au/Ag复合材料逐渐展现出作为SERS衬底的优势,被广泛应用于生物、化学、医疗等领域。本文综述了近些年来基于多孔硅复合Au/Ag纳米颗粒混合平台的研究,重点讨论了将贵金属Ag/Au复合于多孔硅衬底上的制备方法,介绍了它们在不同制备条件下枝晶结构的生长形貌和检测性能,并对多孔硅-Ag/Au枝晶复合结构作为SERS衬底的未来发展进行简要分析。

Abstract: Porous silicon-Au/Ag dendritic composites have gradually demonstrated their advantages as SERS substrates since the discovery of surface-enhanced raman scattering (SERS) in the 20th century. They have found widespread application in biology, chemistry, medical treatment, and other fields. The advantage of SERS substrate porous silicon, focusing on Ag/Au in preparing the porous silicon substrate method, was examined over recent years. The porous silicon substrate with a metal coating is cost-effective to fabricate and offers a high detecting capability. This paper illustrates the application in the morphology of dendritic structures under different conditions of preparation and detection. A short analysis carried out on the future evolution of the porous silicon-Ag/Au dendritic composite structure as a SERS substrate.

Key words: porous silicon, surface-enhanced Raman scattering (SERS), AgNPs/AuNPs, complex meterial, dendritic structure
