| Outline of Final Research Achievements |
The objective of this project was to prepare mechanically-flexible artificial bones, applicable to any bone-void shapes, with enhancing effect for bone regeneration through releasing inorganic ions such as calcium and silicate ions.
Siloxane-containing calcium carbonate particles were embedded in poly(hydroxylalkanoate), and the resulting composites were shaped into a cotton-wool-like structure composed of ~10 um-fiber skeletons. The fibers were successfully coated with hydrophilic aluminum silicate nanotubes (imogolite).
The materials could release calcium and silicate ions gradually, and showed an excellent protein adsorption ability and the healthy proliferation of osteoblast-like cells.
