Effect of peptide orientation on electron transfer

Effect of peptide orientation on electron transfer

We have developed a methodology for the in situ derivatisation of histidine residues in self-assembled monolayers of peptides with redox-active groups, and have shown by electrochemical methods that the average dipole of peptide films on gold affects the heterogeneous electron transfer properties.
