Abstract

This study proposes a facile and general method for fabricating a wide range of high-performance SiO@Au core-shell nanoparticles (NPs). The thicknesses of Au shells can be easily controlled, and the process of Au shell formation was completed within 5 min through sonication. The fabricated SiO@Au NPs with highly uniform size and SERS activity could be ideal SERS tags for SERS-based immunoassay.

摘要

本研究提出了一种简便通用的方法来制备多种高性能的SiO@Au核壳纳米粒子（NPs）。金壳的厚度可以轻松控制，并且通过超声处理在5分钟内即可完成金壳的形成过程。所制备的尺寸高度均匀且具有表面增强拉曼散射（SERS）活性的SiO@Au NPs可成为基于SERS的免疫分析的理想SERS标签。
