  • METHOD FOR SELECTIVE CELL ATTACHMENT/DETACHMENT, CELL PATTERNIZATION AND CELL HARVESTING BY MEANS OF NEAR INFRARED RAYS
    Publication number: 20150044770
    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.

  • Alkali-soluble resin and negative-type photosensitive resin composition comprising the same
    Patent number: 8951713
    Abstract: An alkali-soluble resin is provided. The alkali-soluble resin is prepared using a polyfunctional thiol compound as a chain transfer agent. The alkali-soluble resin has a lower viscosity than a resin having the same molecular weight. Further provided is a negative-type photosensitive resin composition comprising the alkali-soluble resin as a binder resin. The use of the alkali-soluble resin lowers the overall viscosity of the photosensitive resin composition to effectively reduce the height of a stepped portion of a photoresist pattern using a small amount of the photosensitive resin composition.
