Plasmonic optical trap having very large active volume realized with nano-ring structure

Plasmonic optical trap having very large active volume realized with nano-ring structure

The feasibility of using gold nano-rings as plasmonic nano-optical tweezers is investigated. We found that at a resonant wavelength of λ=785  nm , the nano-ring produces a maximum trapping potential of ∼32k B T on gold nanoparticles. The existence of multiple potential wells results in a very large...
