POLYMER MEMBRANE AND METHOD OF MANUFACTURING THE SAME

Provided is a method (100) of fabricating a polymer membrane (206) suitable for a cell culture device. The method comprises providing (102) a first polymer (200) having a first surface (201), and providing (104) a solution (204) on the first surface. The solution comprises a second polymer, a surfactant, and a solvent. The surfactant comprises surfactant molecules each having a polar moiety. The method further comprises evaporating (106) the solvent while the solution is on the first surface to provide the polymer membrane. The polymer membrane has a second surface (207) in contact with the first surface. At least the first surface of the first polymer has greater affinity for the polar moiety than the second polymer. Further provided is the polymer membrane per se, a fluidic device, such as a cell culture device, comprising such a polymer membrane, and a cell culturing method comprising encapsulating cells with one or more of the polymer membrane.
