Optically-induced dielectrophoresis (ODEP)-based bio-manipulation is a new paradigm for cell manipulation as it offers most of the capabilities of laser-based tweezers, but requires 100 times less optical power and with at least a 10-times reduction in system cost. Our research groups at City Univer.....

The technology is a closed-loop cable driven system whose gondola or platform is free to move up and down with feedback control. The system with serving tools provides a positive contact with the wall surface. Contact pressure is maintained by the cable system itself as the cables remain taut while .....
