Abstract
A fast, generic, and suspension-based route to highly SERS-active assemblies of noble metal nanoparticles (Au, Ag) with small core-satellite gaps and single-particle Raman sensitivity is presented. Rationally designed, heterobifunctional Raman reporters serve as molecular linkers for electrostatic conjugation of the small satellites to the large core.
摘要
本文提出了一种快速、通用且基于悬浮液的方法，用于制备具有小核-卫星间隙和单颗粒拉曼灵敏度的高表面增强拉曼散射（SERS）活性贵金属纳米颗粒（金、银）组装体。经过合理设计的异双功能拉曼报告分子用作小分子卫星与大核静电共轭的分子连接体。
