  • Method for fabricating an embedded pattern using a transfer-based imprinting
    Patent number: 9791601
    Abstract: In a method for fabricating an embedded pattern using a transfer-based imprinting, an adhesive layer is formed on a substrate. The adhesive layer has a photo curable resin. A stamp having a protruded pattern is prepared. A thin-film layer is formed on an outer surface of the protruded pattern of the stamp. The stamp having the thin-film layer contact with the adhesive layer is pressed to selectively transfer the thin-film layer of the protruded pattern to the adhesive layer. Ultraviolet rays (UV) are irradiated to cure the adhesive layer. The stamp is removed.
    Type: Grant

  • Nano-fibered membrane for western blot and manufacturing method of the same
    Patent number: 8512612
    Abstract: The present invention relates to a membrane for Western blotting which has a three-dimensional open pore structure, an average pore diameter of 0.1-1.0 ?m and a thickness of 30-200 ?m, wherein the membrane for Western blotting is manufactured by subjecting nanofibers having an average fiber diameter of 50-1000 nm, obtained by electrospinning, to a hot-plate calendering process, and a method for manufacturing the same. The method comprises the steps of: dissolving a hydrophobic material in a solvent to prepare a spinning solution; subjecting the spinning solution to a spinning process to obtain a hydrophobic polymer nanofiber web; and calendering the obtained nanofiber web to obtain a membrane for Western blotting.
