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...

Zusammenfassung: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 metal layer.
