WebDec 2, 2024 · Trapped Objects. Whereas all particles that respond to certain criteria (shape, size, charge) can be trapped by optical tweezers, the most used particles in biology and biophysics experiments are microbeads. These commercially available beads can be made with silica or polystyrene, and have dimensions ranging from 0.5 to 10 microns. WebOptical tweezers produce a restoring force to hold the micrometer-sized plastic microsphere at the focus. This restoring force is linearly related to displacement (i.e., it is Hookean) over a distance of about ±250 nm. The bead position can therefore be used to measure both force and movement.
