Abstract
Microgrippers adapted to capture, manipulate, and contain single cells in both in vitro and in vivo cell applications are disclosed. The energy required to actuate these microgrippers is derived from the release of residual stress and does not require any wires, tethers, or batteries. Because the microgrippers are made from biocompatible and biosorbable materials, they do not accumulate in tissue. Accordingly, they can be used for in vivo applications, such as for gripping single cells in tissue biopsies.
