Outline of Final Research Achievements

The significant progresses have been seen in integrating chemical and biological laboratory on 10-100 um space (microspace). Recently, the research target is going into 10-100 nm space (extended-nano space). However, the extended-nano space is smaller than even wavelength of light, and the technololical difficulties exist for fabrication, detection, and fluidic control. Here, I focused on optical near-field light (ONF), which is generated around nanostructures with the size less than optical diffraction limit. In this study, I developed　photochemical processes for the extended-nano space by utilizing ONF, top-down fabrication method, and bottom-up fabrication method. This method will contribute to device technologies utilizing extended-nano space such as single cell and single molecule analytical devices.
