Hydrogel-based electrical stimulation culture system to control the engineered cellular activities driven by nano biomolecules

The hydrogel-based electrical stimulation culture device composed of portable cellular micropatterns and the flexible and stretchable PEDOT/PU electrode arrays were developed to afford in vitro cell-based bioassay system. Electrical regulation of muscle cellular contraction driven by intracellular nano-actuator composed of biomolecules was successfully demonstrated by using this system.
