| Research Abstract |
The plasmonic nanostructures for stable optical trapping of Brownian molecules and nanoparticles were obtained with electromagnetic simulation. The suggested structures were fabricated and their properties of light localization were assessed using a newly developed near-field microscope. Along my research proposal, it was quantitatively demonstrated that the plasmonic nanostructures significantly improves the trapping performance compared with conventional methods.
