Isolating and Probing the Hot Spot Formed between Two Silver Nanocubes

Year: 2009

Type: article

Abstract: Out of the frying pan: Hot spots can greatly increase the sensitivity of surface-enhanced Raman scattering, but they remain poorly understood. A new strategy based on plasma etching (see picture) can be used to isolate and exclusively probe the SERS-active molecules adsorbed in the hot-spot region between two silver nanocubes.
