Outline of Final Research Achievements

Amorphous calcium phosphate (ACP) film known as bioresorbable material was focused on the surface modification of bone substitutes to improve the bone compatibility. Controlling the bioresorbability and giving the antibacterial activity to the ACP film were conducted by addition of elements and Ag, respectively. Nb and Ta addition to ACP film suppressed the bioresorbability of ACP film. Ag added ACP film showed antibacterial activity against E. coli and S. aureus.
