Surface-Enhanced Raman Scattering of Luminol on Silver and Silver-Gold Alloy Nanoparticles

Description

We report assignments for the Raman and surface-enhanced Raman scattering (SERS) spectra of luminol on Ag and AgxAu1-x alloy nanoparticles. From this we can determine the relative orientation of luminol with regards to the surface and that as the amount of silver in nanoparticle composition increases, so does the intensity of the SERS signal. Systems with a strong SERS signal are of interest for their potential use in bioimaging techniques.
