Facile synthesis of high-performance SiO₂@Au core-shell nanoparticles with high SERS activity.

ABSTRACT: This study proposes a facile and general method for fabricating a wide range of high-performance SiO₂@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 SiO₂@Au NPs with highly uniform size and SERS activity could be ideal SERS tags for SERS-based immunoassay.
