Patents by Inventor Byeong Gwan Kim

Byeong Gwan Kim has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

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

  • Patent number: 9096779
    Abstract: An electroconductive transparent adhesive composition containing a transparent adhesive monomer, any one electroconductive mesoporous filler selected from the group consisting of porous carbon, an electroconductive polymer and combinations thereof, and a polymerization initiator, and an electroconductive transparent adhesive produced using the composition are provided. The electroconductive transparent adhesive composition is less expensive and highly economically efficient, and has excellent electrical conductivity and transparency, and has excellent mechanical strength. Thus, the electroconductive transparent adhesive composition can be used in a variety of electrical and electronic applications such as touch screens, displays, and electronic devices.
