  • Synthesis and preparation of novel functional artificial bone materials based upon calcium phosphate ceramics.
  • Creation of novel high-functional materials utilizing microstructures of biominerals.

A porous artifi cial bone (Left: Already commercialized) and a self-setting bone paste (Right) in which hydroxyapatite and collagen have a bone-like nanostructure.


  • Chemical compositions and nanostructure of materials induce appropriate reaction from cells and higher structures such as interconnected pores affect viability and carrying of cells.
  • We are preparing hydroxyapatite and other calcium phosphates; and their composites with biopolymers and synthetic polymers. Further, we are optimizing their nano to micro scale structures to depelop novel bone regeneration materials and prostheses for hard tissues.
  • In addition, we are utilizing biomineral microstructures, which still cannot be mimicked artifi cially, to create novel and high functional materials for artifi cial bone and environment cleanup.

Removal of fluoride ion using water cleanup material prepared from sea urchin test, a marine waste. Fluoride ions removed less than 8 mg/L, the emission standard of Japan.
