Engineering “hot” nanoparticles for surface-enhanced Raman scattering by embedding reporter molecules in metal layers
Ag is deposited on the surface of Au nanoparticles functionalized with 4-mercaptobenzoic acid (MBA). Exceptionally strong surface-enhanced Raman scattering (SERS) signals are observed from the resulting colloid. Using SERS as a tool, evidence is obtained for the embedding of MBA inside the nanoscale...
