Optical Trapping and Manipulation of Superparamagnetic Beads Using Annular-Shaped Beams
We propose an optical tweezers setup based on an annular-shaped laser beam that is efficient to trap 2.8 [Formula: see text] m-diameter superparamagnetic particles. The optical trapping of such particles was fully characterized, and a direct absolute comparison with a geometrical optics model was pe...
