Abstract
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.
