Outline of Final Research Achievements |
As a novel feature to be incorporated into atomic force microscopy (AFM), we conducted a fundamental study of a nanofabrication and nanomeasurement technique that can selectively degrade targeted membrane proteins at the single molecule level. In this study, we developed the photocatalytic nanofabrication of living cell membranes based on highly localized photochemical oxidation with a catalytic titanium dioxide (TiO2)-functionalized AFM probe. Moreover, we also developed antibody-modified AFM probes functionalized with Ag nanoparticles for incorporating a highly specific molecular recognition ability. The realization of the novel AFM-based technique is expected to be an innovative technology required to support future advances in nanotechnology and biotechnology.
