Introduction of Research
To understand nanophotonics generated around nanostrcutres and to apply nanophotonics to novel analytical technologies and biosensors. Specifically, we work on the plasmonic enhancement field obtained by the resonance of light with free electrons in nanostructures. Understandings the plasmonic properties of various materials such as metals and graphene from the viewpoint of electronic and optical properties enable us to control them, and finally to analyze single molecules and/or single nanoparticles by using the plasmonic enhancement field. For example, we are recently interested in plasmonic nanopore devices for DNA, RNA, and bio-nanoparticles.
