surface-enhanced Raman spectroscopy 

Acronym: SERS
https://doi.org/10.1351/goldbook.08689
Measurement method of Raman spectroscopy by which the intensity of vibrational bands in the Raman spectra of molecules within a few nanometers of the surface of microscopically rough metals, metal colloids and metal nanoparticles is increased by several orders of magnitude.
Notes:
  1. The metals that give the largest enhancement are silver, gold and copper, but this phenomenon has been reported to occur with a range of other metals.
  2. Other mechanisms of enhancement are known but the common usage of SERS is with a metal or with related systems and implies enhancement through interaction with a surface plasmon.
