| Outline of Final Research Achievements |
I proposed novel nanofabrication techniques based on highly localized chemical reaction using a catalytically active atomic force microscope (AFM) probe. By employing a Pt-coated AFM probe as a tool for nanomachining, nanoscale grooves can be fabricated on a Si surface at room temperature via Pt-assisted catalytic chemical etching in just water without adding any chemicals to be used as an etchant for Si. Moreover, the photocatalytic decomposition (patterning) of DNA molecules can be performed under UV irradiation based on localized photochemical oxidation using a TiO2-coated AFM probe. I also demonstrated that this technique can be applied to penetrate a cell membrane for intracellular delivery.
