Paper Abstract

Gold nanoparticles have found broad applications in nanomaterials and nanobiotechnology and health care. They are considered to be superior handles or probes relative to polystyrene beads for their own specific physical characteristics. But unfortunately they are considered difficult to trap stably by optical tweezers still owing to their specific physical characteristics. In this paper, numerical studies are carried out to show that how the radiation forces on the gold particles dependant on the parameters of the lasers and of the particles. The results show that a stable trap for gold particles needs a more strictly choice of lasers than polystyrene nanobeads for given particle size and other conditions.
