SERS Substrates

The SERS (Surface Enhanced Raman Scattering) technique is known to be a powerful method for chemical and biological sensing applications. It is now a very effective tool to analyze molecules by highly increasing the Raman signal intensity coming from molecules which have been adsorbed on nano-sized metal structures, in particular Au, Ag or Cu.

HORIBA Scientific proposes SERS substrates which offer excellent reproducibility and significant enhancement allowing detection of molecules which otherwise could not be detected using classical Raman spectroscopy, and easier/faster analysis of weak Raman scatterers. The substrates are available in different sizes, coated with pure gold.
