| Outline of Final Research Achievements |
The Raman spectroscopy studies based on the encapsulation of beta-carotene into SWCNTs revealed that there are three types of oxidative corrosion of SWCNTs, resulting in non-oxidized, end-cap oxidized (end-cap eliminated) and side-wall oxidized SWCNTs, have been sensitively separated from Raman spectra using the encapsulation of beta-carotene into the SWCNTs, and the diagram of oxidative corrosion types of potential vs. pH has been obtained.
The bioelectrocatalytic current for the DET reaction of Lac immobilized onto the N-doped SWCNTs (N-SWCNTs) tended to decrease with increasing N dopant ratio, whereas the amount of Lac adsorbed per BET surface area of the N-SWCNTs did not depend on the N dopant ratio. We carefully concluded that the above behaviors may be due to denaturation and/or decreasing of the DET reaction rate caused by the strong electrostatic interaction between Lac and the N-SWCNTs surface.
