Magnetoplasmonic nanoparticles, such as Au-Fe alloys, are very interesting for their properties. In this article, the optical trapping of Au-Fe nanoparticles are investigated as a function of Fe atomic percent doped in gold nanoparticles, theoretically. Using a generalized Lorenz–Mie theory, it is shown that the maximum force exerted on the alloyed nanoparticles enhances about 75% with increasing Fe atomic percent. It is shown that the trapping strength is depth-dependent and shows a 20% increment in shallow positions and a 17% decrement in the axial direction in the optimal depth, which is deep inside the sample. Wavelength dependence of alloyed nanoparticles is studied too.

Standard optical tweezers are often built as inverted microscopes consisting of reflective, diffractive or refractive optical components. These optical elements are used to adapt the laser beam size, shape the beam profile and finally to generate the optical trap. Each optical component potentially suffers from various aberrations. In this contribution we investigate the effect of aberrations on the trapping performance.
