Application note: Surface enhanced Raman spectroscopy (SERS) imaging using the inVia confocal Raman microscope (pdf)

Raman imaging is a powerful research tool for understanding the molecular composition, structure and distribution of different chemical species. Nano silver/gold colloids and roughened metallic substrates can be used to amplify the intensity of the Raman scattering of adsorbed molecules via SERS. This can increase the sensitivity and/or the specificity of the analysis. SERS imaging can be used to evaluate the efficacy of delivery of nanoparticles (NPs) into cells/animals. SERS measurement of labelled or surface-modified NPs can also be used for biosensing, multiplexing and theranostics.
