Abstract
This paper reports on assembling method for 3D cellular structure. The precise and automated system for the 3D tissue construction is important for regenerative medicine. Large size functional 3D tissue needs blood vessel-like structure for supplying oxygen and nutrients. For constructing complicated structure like these, micro-heater and thermoresponsive gel is focused. Using this device and thermoresponsive gel, 2D arbitary structure can be constructed. And assembling the 2D structures, 3D structure having 2D arbitary structures is possible to be constructed. In order to put this in practice, at first, change of gelation ragne by heating time and electricity is confirmed. As the result, optimal condition for grasp is obtained. Furthermore, grasping and releasing two micro objects by heating and gelation two points is successed.
