Abstract
In one example embodiment, a protein-immobilized electrode is stably used for long time. In one example embodiment, a method of manufacturing the protein-immobilized electrode includes immobilizing cytochrome c552 having high stability to a chemically-stable gold electrode while maintaining electron transfer capability of the cytochrome c552. In one example embodiment, a self-assembled monolayer is formed on a gold electrode by using hydrophobic thiol and hydrophilic thiol. By dipping the gold electrode on which the self-assembled monolayer is formed in a cytochrome c552 solution, a protein-immobilized electrode in which a cytochrome c552 is immobilized to the gold electrode with the self-assembled monolayer in between is produced.
