Paper Title:
Properties of Different Nano-Metallic Particles in Optical Trapping
  Abstract

Metal nanoparticles are well-known to exhibit a strong interaction with light, which have very important applications and one of them, recent years, is optical trapping of the metallic nanoparticles. Based on the principle of the optical trapping for metallic nanoparticles, in this paper, the gradient forces and the scattering forces in the optical trapping for gold-, silver- and copper-nanoparticles have been analyzed and calculated numerically. Typical power spectra for gold-, silver- and copper-nanoparticles have been obtained. It is shown from the calculation results that under what condition these metallic nanoparticles can be trapped, and the stability of the potential well for these metallic nanoparticles has been analyzed in order to know whether the well was deep enough for overcoming the gravity and Brownian motion.
