| Outline of Final Research Achievements |
In the present study, we aim to develop novel molecular separation and crystallization techniques based on plasmonic optical tweezers. For the goal, we mainly demonstrated three intriguing results: (1) semi-selective optical trapping of fluorescent dye nano-aggregates, (2) plasmonic molecular extraction and detection based on plasmonic optical trapping of thermoresponsive polymers, and (3) development of nanostructured semiconductor-assisted optical trapping.
