Current Research

Optical tweezers use the radiation forces generated from a strongly focused beam to trap small particles. The ability to trap a living cell non-invasively with optical tweezers has the potential for many biological applications. In this project, we attempt to integrate optical tweezers with an optofluidic microscope (OFM). The current design utilizes a high-powered Ti-Sapphire laser and a 40x water immersion lens for trapping. With this setup, the trapping of live Chlamydomonas on the order of 10um by 10um has already been shown. The completion of this project will provide a new and innovative way to image cells.
