PTFE材を用いたマイクロゼラチンファイバーの型成形

抄録

Gelatin is useful biomaterials for biofabrication. The property of gelatin is unique. The state is changed to sol or gel by temperature. Utilizing the property of gelatin, we are able to fabricate cave for artificial vessels in biodevices. Therefore, micro gelatin fibers are useful devices for fabrication of artificial vessels. In this paper, we made a mold for fabrication of micro gelatin fibers. We used PTFE for molds, because it has non-adhesive. Then, we made micro gelatin fibers which were 20～100 μm in width utilizing the mold. Machining marks of the mold were transcribed on the surface of micro gelatin fibers. We are able to fabricate cave with arbitrary shape for artificial vessels utilizing micro gelatin fibers.
