The interaction between riboflavin and silver colloidal particles was studied with absorption and surface enhanced resonant Raman spectroscopy (SERRS). It was found that flourescence interference was completely quenched while Raman scattering was significantly enhanced upon addition of silver sol into ri boflavin aqueous solution. Tentative assignment of Raman modes was given. SERRS sp ectra suggest that Ag complexation of riboflavin in silver sol dose not resemble the aqueous solution complex of Ag. In addition, Raman bands below 1000 cm-1, which are mostly related to ring breathing and C-H torsion out of plane, were also obtained.
