Article Synopsis
- Biocompatible tripeptide self-assembled monolayers (SAMs) were engineered with a carboxylate group to attract lysine around the cytochrome heme site, forming a specialized electroactive structure on a gold electrode.
- Exposure of the peptide/Au electrode to cytochrome led to a measured surface coverage of 11 ± 3 pmol/cm, and atomic force microscopy provided detailed images of the protein layer with minimal surface roughness.
- Electrochemical analysis showed that the protein's surface charge impacts its redox behavior, with shifts in formal potential and accelerated electron transfer rates observed for cytochrome when bound to tripeptide/Au compared to traditional SAMs.
