He has been working on the research field of surface chemistry and nanotechnology. He has studied electrical and optical properties of low dimensional nanostructures and its growth. He has developed growth technique of metal oxide nanorods and SWCNTs. He has also developed measurement techniques with multiple-scanning-probe microscope and studied electrical properties of 1D nanowires. He has developed probe technology in particular. He has developed ultra fine probes for electrical conductance measurements in multiple-scanning-probe microscope. He has developed highly sensitive molecular identification SERS probe with metal oxide nanorods for application of multiple-scanning-probe microscope to bionanotechnology field.
