Patent number: 10385303Abstract: 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.Type: GrantFiled: November 29, 2016Date of Patent: August 20, 2019Assignee: Industry-Academic Cooperation Foundation, Yonsei UniversityInventors: Eun Kyoung Kim, Hyun Ok Kim, Jung Mok You, Jeong Hun Kim, Tea Hoon Park, Byeong Gwan Kim, June Seok Heo, Han Soo Kim
