Welcome to IASBS optical tweezers group page!
Optical tweezer refers to a particular geometry where a laser beam is focused through a high numerical aperture lens. This geometry is used to generate a three-dimensional optical trap by exerting a radiation force to small objects. Present days optical traps have become calibrated tools to immobilize, orient and transport submicron particles. The nanometer positioning ability, along with sub-picoNewton force resolution, have turned optical tweezer into a valuable tool in biology and physical sciences. </
