ABSTRACT
We explored experimentally and theoretically the optical properties of isolated silver trimer-dipeptide bioconjugates. The metallic moiety induces a strong enhancement of the optical absorption of the peptide. We also show that its binding to a peptide can reduce the conformational flexibility and induce transitions between secondary structures.
