Title: Fabrication of gel sheet utilizing hysteresis characteristics of temperature responsive polymer
Inventor: TAKEUCHI MASARU
IPC: C12N11/08
Filed: 2013-08-04
Abstract: PROBLEM TO BE SOLVED: To provide a method for fabricating a reconfigurable structural object in which a structure including a cell scaffold can be easily built and erased.SOLUTION: As temperature responsive polymer solution, one having hysteresis characteristics in which gelation starting temperature is higher than solation starting temperature is used. As the temperature responsive polymer solution in a heat-retaining state is locally heated by using the solution heater, only a heated area exceeds the gelation starting temperature, and a gel sheet is generated around the solution heater. Then, when heating by the solution heater is stopped, the generated gel sheet does not return to sol due to the hysteresis characteristics and the shape of the gel sheet can be maintained. Thus, by using the hysteresis characteristics that the temperature responsive polymer solution has in which the gelation starting temperature is higher than the solation starting temperature, it becomes possible to maintain the fabricated gel sheet in a gel state.
