Electrochemistry of peptides

This opinion is focused on the electrochemistry of peptides utilised in biological and technological processes. The redox behaviour of peptides important in biomedicine, neuropeptides and antimicrobial peptides is highlighted. In addition to peptides composed of essential amino acids, peptide-mimetic molecules such as peptide nucleic acid and artificial peptidic wires transferring protons and electrons are reviewed. The application of electrochemistry for the research of peptide–membrane and peptide–surface interactions is also discussed
