Patent number: 11920118Abstract: Provided are a method for fabricating a highly elastic porous polymer membrane, a method for manufacturing a cell culture system using a porous polymer membrane fabricated by the fabrication method, and a cell culture system manufactured by the manufacturing method. The porous polymer membrane can be fabricated by spin coating a mixture solution containing a biodegradable elastomeric polymer and a water-soluble moisture absorbent in an optimum ratio while maintaining a high relative humidity. The porous polymer membrane has a uniform thickness and a uniform pore size and is highly elastic. In addition, the thickness and pore size of the porous polymer membrane can be controlled. The porous polymer membrane can induce active cell-cell interaction during cell co-culture due to its high porosity. The porous polymer membrane enables control over cell alignment or array due to its high biocompatibility and elasticity.Type: GrantFiled: October 27, 2020Date of Patent: March 5, 2024Assignee: Korea Institute of Science and TechnologyInventors: Young Mee Jung, Soo Hyun Kim, Justin Jihong Chung, Jin Yoo, Tae Hee Kim
