To investigate the biomineralization behavior of silk fibroin and to valuate the biodegradation and biocompatibility of the hybrid biomaterial, the calcium phosphate deposits were identified with SEM, EDX, XRD and FTIR. The results reveal that supersaturated calcification solution is an effective method for the mineralization of fibroin film. Enzymatic degradation experiment demonstrates the biodegradability of the composites. Osteoblasts incubation shows an excellent cytocompatibility on the mineralized fibroin films.
