Dithiocarbamate-coated SERS substrates : sensitivity gain by partial surface passivation

The surface-enhanced Raman scattering (SERS) activity of nanoporous gold (NPG) can be boosted by controlled surface passivation. The SERS activities of unfunctionalized NPG were first optimized by etching substrates with NaI/I(2) (triiodide) and using 2-mercaptopyridine (2-MP) as the probing analyte...
