Abstract
Surface-enhanced Raman scattering (SERS) of xanthopterin adsorbed on colloidal silver was measured and the Raman spectrum calculated by the density functional theory method was also obtained. Xanthopterin can be detected down to 5 × 10-9 M and the enhancement of the scattering intensity is at least 105-fold. Xanthopterin molecules are adsorbed flatly on the surface of the Ag particles. This study shows that SERS could be another prospective method for the detection of pterines.
