Title: METHOD FOR SELECTIVE CELL ATTACHMENT/DETACHMENT, CELL PATTERNIZATION AND CELL HARVESTING BY MEANS OF NEAR INFRARED RAYS
Abstract:
The present invention relates to a method for selective cell attachment/detachment, cell patternization and cell harvesting by means of near infrared rays. More particularly, conducting polymers or metal oxides having exothermic characteristics upon irradiation of near infrared light is used as a cell culture scaffold, thus selectively attaching/detaching cells without an enzyme treatment. The scaffold has an effect of promoting proliferation or differentiation of stem cells, and therefore, can be used as a stem cell culture scaffold. The scaffold enables cell attachment/detachment without temporal or spatial restrictions, thus enabling cell patternization.
