Direct Manipulation of Adherent Cell by MEMS Tweezers

We developed MEMS tweezers to manipulate an adherent cell, which consists of probes for cell trapping, a comb-drive actuator, and a sensor to detect a dish surface. A double-folded beam was employed as a spring for a large displacement of the probe with stability. Peeling a HeLa cell off from a dish and trapping it were successfully conducted by the MEMS tweezers.
