About Our Group

We are interested in multiple aspects of optical micromanipulation, new microscopy techniques, and imaging. Current projects in our group primarily deal with the optics and applications of optical tweezers. Optical tweezers refer 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 on tiny particles. Optical tweezers with nanometer positioning ability, along with sub-picoNewton force resolution, have become a valuable tool for micromanipulation in biology and physical sciences.
