Abstract
⺠We show that investigated molecules bind to a colloidal silver surface mainly through Trp8 and Met14. ⺠Trp8 adsorbs at the surface almost perpendicularly. ⺠Met14 appears on the surface mainly as a PC-G conformer. ⺠His12 practically does not take part in the adsorption process. ⺠Substitution of Leu13 by Phe does not change substantially the pattern of the adsorption mechanism. ⺠Modification such Phe12 and Tyr6 cause changes in the SERS spectra.
