Abstract
Convection- and bubble-assisted nanoaperture-based plasmonic tweezers are presented to overcome the diffusion-limited trapping. Opto-thermally generated convection and bubble-induced flows rapidly transported particles from large spatial extent to plasmonic nanoapertures without relying on diffusion. The trapping time was reduced by more than order of magnitude. Moreover, the trapping time was brought within practical time limits at ultralow particle concentrations for which it could take several hours to trap a single particle.
