Surface Enhanced Raman Spectroscopy (SERS)

A molecule adsorbed on a corrugated metal produces a Raman signal which is 6 to 12 orders of magnitude more intense than the signal it would emit if deposited on a flat substrate. The enhancement comes from the increase of the local optical field intensity in the proximity of sharp points of textured metals [Au, Ag, Cu], or in the nano-scale gaps between colloidal particles
