Abstract
Precisely focused laser beams produce optical forces when coming into contact with particles. Using these forces, it is possible to "tweeze" microscopic particles, moving them in 3D space. With the aid of a microscope and a photodiode, the location and velocity of these particles can be quickly and accurately tracked. This procedure could have applications in biomedical research, electrical microcircuits, and many other fields.
