Isolating and probing the hot spot formed between two silver nanocubes

Angew Chem Int Ed Engl. 2009;48(12):2180-4. doi: 10.1002/anie.200806139.

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.
