(XH)₄ peptide, which is composed of histidine that interacts with metal ions such as copper for catalysis in enzymes and other amino acids, was newly developed and its self-assembled structure on graphite in the presence of metal ions was evaluated by AFM. The results showed that the self-assembled structure was changed by the presence of copper ions.
