| Outline of Final Research Achievements |
In this study, the hybrid-interface control was applied to the interface between hydroxyapatite and bioabsorbable polymer. By control of the interface-control ratio, it was made possible to create hydroxyapatite/bioabsorbable polymer composite scaffold, which can improve the fracture and hydrolysis properties. Then, polycaprolactone was chosen as a bioabsorbable polymer, where hybrid-interface control can be applied and which can be dissolved by osteoclasts. It was suggested that osteoclastic metabolic behavior can be controlled by the control of the substrate elastic modulus. In addition, it was suggested that the microstructure, where both osteoblasts and osteoclasts can be controlled, can be designed by combination of hydroxyapatite and carbonate apatite.
