| Outline of Final Research Achievements |
We developed a new method to modify metal nanoparticles in the vicinity of a base electrode surface using non-conducting supporting materials, such as paper or cloths, and explored the possibilities of the proposed modified electrodes for the advances of voltammetric analysis. Actually, non-conducting Kimwipe paper or cotton gauze could be modified to hold metal nanoparticles, such as gold or platinum, inward. Using the modified materials, we studied the mechanistic aspects of the promotion of electron transfer reactions on the metal nanoparticle-modified electrode and the effects of metal species on them. Furthermore, in the application for the electroanalysis of myoglobin, we verified the possibility of highly sensitive detection and clarified the effects of the holding properties of analytes on the vicinity of the electrode surface.
