  • Publication number: 20160206778
    Abstract: Embodiments of the present invention relate to a biodegradable scaffold for replacing tissue or inducing tissue regeneration and a preparation method thereof, wherein the scaffold comprises at least one woven silk tube layer and a collagen layer inside the tube layer. The scaffold is excellent in terms of tissue regeneration and mechanical properties and causes little or no immune response after implantation. Thus, the scaffold can be effectively used as a matrix for the regeneration of ligaments and tendons and the repair of injured muscles.

  • Patent number: 8455373
    Abstract: The present invention provides ink-jet printing ink for organic semiconductors, and, more particularly, provides ink-jet printing ink for organic semiconductors, which can be used to form a uniform crystalline thin film. The ink-jet printing ink of the present invention includes a mixed solvent composed of a first solvent and a second solvent having a higher boiling point and lower surface tension than the first solvent, thus forming a uniform crystalline thin film in a volatilization process. Further, the present invention provides a circular organic thin film transistor having a high field-effect mobility of about 0.12 cm2V1S?1.
