| Research Abstract |
For preparing thermally modulated bio-interface that separates cells without the modification of cell surfaces for regenerative medicine and tissue engineering, thermo-responsive hydrophobic copolymer brushes were formed on glass substrate. Prepared copolymer brush surfaces were characterized by observing the adhesion at 37 C and detachment at 20 C or 10 C of four types of human cells. Endothelial cell and fibroblast exhibited their effective detachment temperature at 20 C and 10 C, respectively. Using cells' intrinsic temperature sensitivity for detachment from the copolymer brush, a mixture of endothelial cell and fibroblast was separated.
