| abstract |
The present invention relates to a bioink which is prepared from silk fibroin, a natural protein fiber, and from which biological tissues having improved cytocompatibility and outstanding mechanical properties can be prepared by means of a 3D printer, and a preparation method therefor. By 3D printing, the present invention can prepare a biological tissue having mechanical properties such as moisture absorbency, volume expansion rate, compressive strength, tensile strength, etc. In addition, the preparation of a bioink including silk fibroin as a base skeleton allows for the construction of a biostructure which causes almost no immune response in the body and thus is superb in biocompatibility. |
