Fluorescence features of some organic compounds and proteins adsorbed on rough silver surfaces

摘要

Abstract: Fluorescence spectrum of flavin adenine dinucleotide adsorbed on the silver electrode was obtained. Dependences of the fluorescence intensity and the surface enhanced Raman scattering intensity on the electrode potential were similar. It was found that the 1,3,5- threephenil pyrasole molecules adsorbed on silver island films (SIF) undergo photo- transformation at a radiation with 458 nm. The products of this transformation have got an intensive fluorescence in the range from 500 to 600 nm. It was found too the surface enhanced fluorescence of 2,6-TNS bound with human serum albumin adsorbed on SIF. !11
