Abstract:   (1907 Views)
Optical trapping of metal particles, especially gold nanoparticles is very important for investigation of living cells. Despite, better trapping of metals with respect to polystyrene beads, so much heat is created during trapping because of their high absorption. Using hollow spheres are adequate to decrease the created heat. In this letter, optical trapping of hollow gold nanoparticles have been investigated. It has been shown that, trapping stiffness in the axial direction increases with reduction of shell thickness, dramatically.
Keywords: Optical tweezers, Lorenz-Mie theory, hollow spheres, gold nanoparticles
