Surface Enhanced Raman Scattering (SERS) is an anomalous enhancement of Raman scattering when molecules are adsorbed to gold or silver nanostructures – this enhancement can be as large as 10¹¹. The advantage of SERS over traditional Raman spectroscopy is its ability to detect analyte concentrations of parts per million, and even parts per billion levels, while Raman spectroscopy works best for pure samples and some simple mixtures.
