Abstract
Surface-enhanced Raman scattering (SERS) is a Raman spectroscopy technique often used to study processes occurring at a solid/liquid interface. In this work, SERS was used to investigate the adsorption of bombesin (BN) and its C-terminal fragments adsorbed onto colloidal gold nanoparticles. Briefly, the SERS results demonstrated that (1) the elongation of the C-terminal peptide fragment causes movement of the Met (L-methionine) side-chain in the direction of the gold nanoparticles and the weakening of the interactions between the amide bond and gold; (2) the His (L-histidine) residue assists in the peptides interaction with the gold nanoparticles; and (3) Trp (L-tryptophan) dramatically changes the SERS spectral pattern on gold.
