| Outline of Final Research Achievements |
Localized surface plasmon resonances are excited at surfaces of noble metallic nanostrcutres by resonant light, resulting in enhanced electromagnetic field of incident light at the surfaces. Plasmonic optical trapping is one of the recent hot topics in the field of plasmonics, since the enhanced electromagnetic field exerts strong radiation force on nanoparticles near the plasmonic nanostructures in comparison with the conventional optical tweezers. The plasmonic optical trapping is potentially applicable to selective trapping and sorting of nanoparticles with different size and shapes.
Plasmonic optical trappings of polystyrene nanoparticles and noble metallic nanoparticles were demonstrated with gold nanohole arrays. These trapping behaviors opened new channel to selective optical trapping and sorting.
