Outline of Final Research Achievements

Hybridization of lipid nanotubes and nanocarbon materials on carbon electrodes are investigated. Enzymes are deposited on the electrodes and the electrodes were subjected to electrochemical measurements. Instead of lipid nanotubes, amine functional polymers were also examined. The results showed that the amine functional polymers accelerated cathode reaction by bilirubin oxidase (BOD) but decelerated anode reaction by fructose dehydrogenase.
Positive effect of the addition of the amine functional polymers were also observed in thermostable enzyme. Addition of chitosan accelerated the enzymatic reaction of thermostable BOD.

Academic Significance and Societal Importance of the Research Achievements

酵素燃料電池の電極修飾にこれまで種々の化合物が検討されてきた。脂質ナノチューブは新しい材料で炭素材料との複合化についても知見がなかった。本研究では両溶媒から高濃度で脂質ナノチューブと炭素材料を複合化する手法を見出すことできた。炭素材料に限らず、脂質ナノチューブと無期刑材料の複合化に向けて、可能性が広がることが期待できる。また、種々のアミノ基含有高分子の添加効果やナノ炭素材料を検討し、酵素燃料電池に好適な材料を見出した。
