Remote-Excitation Surface-Enhanced Raman Scattering Using Propagating Ag Nanowire Plasmons

Abstract

Using propagating plasmons on silver nanowires as an excitation source we perform surface-enhanced Raman scattering (SERS) at a nanoparticle/wire junction located remotely from the laser illumination spot with sensitivities in a few molecules range. Simultaneous multisite remote-excitation SERS sensing can also be achieved.
