| Outline of Final Research Achievements |
Enzymatic biofuel cells, which mimic the metabolic pathway and employ oxidoreductases as catalysts, generate electricity when enzymes metabolize organic compounds. However, there are at least two issues to solve for the application. One is how efficiently enzymes are concentrated on electrodes, and the other is how efficiently extracted electrons are transferred to electrodes. In this study, I tried to resolve these issues by using enzyme crystals, in which enzymes are most concentrated, homogeneously located, and work normally. As a result, I have observed 10 times of current response for anode and 5 times of that for cathode. These results suggest that this new technique enables the production of a biofuel cell with high output.
