    In this contribution we focus on optical forces acting upon a metallic particle or a core-shell particle confined in a standing-wave. The considered spheres are composed either by a gold or silver or the consists of of two layers, one of them is metallic (Au, Ag). We present the results of a computational study where we modify the geometrical parameters of the particles and the wavelength of the trapping beams. Except the optical forces we also deal with heating of the particles. This study may suggest optimal particle composition that may be utilized as an optically trapped probe for Surface enhanced Raman spectroscopy of biomolecules.
