ULTRA-THIN FILM SILK FIBROIN/COLLAGEN COMPOSITE IMPLANT AND MANUFACTURING METHOD THEREFOR
The present invention relates to an ultra-thin film silk fibroin/collagen composite implant for tissue engineering and a manufacturing method therefor. The ultra-thin film silk fibroin/collagen silk fibroin/collagen composite implant according to the present invention has no cytotoxicity and can minimize the influence on cell growth, due to the combined use of a refined silk fibroin aqueous solution, collagen and various biomaterials, and thus can be widely used as an ultra-thin film implant for implanting.
A METHOD FOR BUILDING A STRUCTURE CONTAINING LIVING CELLS
A composition comprising a first material and a second material, wherein said first material is cross-linkable by a first cross-linking reaction and said second material is cross-linkable by a second cross-linking reaction, wherein said first cross-linking reaction and said second cross-linking reaction are inducible by a common activator.

COMPOSITE COMPRISING FABRIC AND POLYAMPHOLYTE HYDROGEL AND PREPARATION METHOD THEREOF
A composite containing a fabric and a polyampholyte hydrogel is provided. In the composite, the polyampholyte hydrogel is a hydrogel of a polymer containing randomly dispersed cationic and anionic repeat groups and at least a part of the fabric is coated with the polyampholyte hydrogel. A method of preparation of the composite involves steps (a) to (c): (a) providing a monomer mixture for preparation of a polyampholyte hydrogel; (b) immersing a fabric in the monomer mixture solution; and (c) polymerizing monomers in the monomer mixture solution to obtain a precursor of the composite.
