Abstract: |
A tissue-engineered bionic bone scaffold with high biocompatibility, bioactivity, degradability and osteoplastic induction has a three-layer structure composed of external degradable compact biofilm layer, central porous layer with less pore diameter for high mechanical strength, and internal porous layer with big pore diameter for transferring nutrients. Said central and internal layers are a composition consisting of in-situ formed nano-phase Ca-P salt and degradable biologic material. |
