Raman and surface enhanced Raman scattering spectra of a black dyed silk sample were registered, and the spectral analysis was performed on the basis of spectra obtained from isolated samples of bombyx mori silk fibroin, reactive black 5 dye and the silk's motive peptide GAGAGS. The conformation of the silk, the peptide and the dye on a silver surface is proposed.
