[13p-C302-10] Local Temperature Elevation and Thermophoresis in Plasmonic Optical Trapping
Keywords:Optical tweezer, Photon Force, Thermophoresis
Plasmonic enhanced electromagnetic field is applicable not only to SERS but also to chemical reaction promotion, and also even to optical trapping. Plasmon-based optical trapping is quite intriguing and is currently attracting much attention in nano-photonics and related research fields, since optical trapping based on surface plasmon can potentially overcome several disadvantages of conventional optical trapping technique using a focused laser beam.
We have developed a plasmonic optical tweezer system and succeeded in novel trapping so far.
(1) Plasmonic optical trapping for organic polymer system.
(2) Resonant optical trapping for polymer microsphere[2] and a protein.
(3) Micro-pattern formation (colloidal crystal formation) on a plasmonic nanostructure.
(4) Quantitative evaluation for radiation pressure and Soret force (temperature elevation at a plasmonic nanostructure) [1, 5].
(5) Femtosecond plasmonic optical tweezer for biomolecules (DNA).
Recent advances of our researches are summarized
