Autoadhesion 현상을 이용한 PCL 세포 지지체 제작 Fabrication of PCL scaffold using autoadhesion phenomenon
pp.25-29
In this article, we proposed a novel technique to fabricate cell‐culturing scaffold, that is, the hollowcylinder‐ grain assembly technique. This technique uses hollow cylindrical particles with sub‐mm thickness. Firstly, we fabricate PCL (polycaprolactone) hollow cylinder with sub-mm thickness using lab-made stainless steel mold. After that, we put the above-mentioned fabricated particles into a metal mold of which temperature could be controlled with hot plate and heat insulation system. PCL particles in the metal mold could be assembled together without severe collapsing under adequate temperature and time. Consequently, we could fabricate scaffold or foam structure with interconnected‐porosity and observed surface of cross section of fabricated scaffold by SEM.
