The basic steps for preparing your sample and performing a dark reference measurement using OceanView Software by Ocean Optics. Both kinds of SERS substrate are used in this video. Surface-enhanced Raman spectroscopy (SERS) is a surface-sensitive technique that enhances Raman scattering by molecules adsorbed on rough metal surfaces or by nanostructures such as plasmonic-magnetic silica nanotubes. br br For more information, visit Get the latest from Ocean Optics.
