| Outline of Final Research Achievements |
The importance of nanomaterial characterization has been increasing with recent advances of nanotechnology and related technologies. In this study, we investigated a technique to accumulate nanomaterials by emitting light onto metallic nanoparticles or nanostructures to induce an amplification of electromagnetic waves called plasmonics, in order to realize improved sensitivity through the concentration of the target nanomaterials. As a result, it was found that concentration in irradiated location of a laser light, transport using temperature gradient, and accumulation using bubbles are possible.
