| Outline of Final Research Achievements |
The aim of this study is to develop an advanced trasnportation method for nanomaterials by exploring molecular trapping by optical radiation pressure or plasmothermal processes, thermophoresis and property-gradient-induced flow, induced by the surface enhanced plasmon resonance around metal nanostructures. A plasmic substrate with gold nanoparticles was fabricated and migration phenomena of nanoparticles in laser irradiation was evaluated. Also, novel temperature and velocity measurement techniques to characterize the plasmic transport were developed.
