Surface-enhanced Raman spectroscopy or surface-enhanced Raman scattering (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.[1] The enhancement factor can be as much as 1010 to 1011,[2][3] which means the technique may detect single molecules.[4][5]
