Advances in single-molecule electrical transport studies of peptides

The charge transport between peptide molecules is one of the crucial factors in sustaining various biochemical processes within biological organisms. Understanding the charge transport processes between peptide molecules is of great significance for further investigating life reaction processes. Through single-molecule electronic characterization techniques, we have reviewed the effects of peptide molecular stuctures and external experimental factors on charge transport. Additionally, we have summarized the latest research on supramolecular interactions between peptide chains, particularly focusing on the even-odd effect. This not only enhances our understanding of the charge transport mechanisms between peptide molecules but also lays a solid theoretical foundation for the widespread application of peptide molecules in fields such as biological devices.
