description	The invention discloses silk protein-tannic acid-ferroferric oxide nano particle hydrogel with a natural source and a preparation method of the silk protein-tannic acid-ferroferric oxide nano particle hydrogel. The fibroin-tannic acid-ferroferric oxide nanoparticle hydrogel disclosed by the invention is prepared by reacting a tannic acid aqueous solution with a fibroin-ferroferric oxide nanoparticle mixed aqueous solution at normal temperature; wherein the mass ratio of the tannic acid to the fibroin to the ferroferric oxide nanoparticles is (0.2-0.4): 5: (0.1-5). The fibroin-tannic acid-ferroferric oxide nanoparticle hydrogel obtained by the invention has the advantages of low price, environmental protection, good biocompatibility, degradability, antibacterial property, relatively strong tissue adhesion, promotion of osteogenesis under the action of an external static magnetic field and the like, and has a good clinical application prospect as a bone tissue adhesive; the selected raw materials are huge in st
