This center makes efforts to create new functional materials technology to be solutions for social and economic issues and to be new core for creation of new industrial field. Here, the functional materials are defined as compounds and structures which exhibit responses against external output. Hence, our activity involves electronic and optical materials to be installed in electronic and optical systems, materials for separation and collection of ions and molecules in solution, biomaterials exhibiting designed interaction with cells and organs and so on. The goal of the center's research and development should be contributed to our society by the utilization of newly developed materials.


Research Group

Bioceramics Group
Bioceramics Group focuses on biomaterials based on ceramics and its composite with polymers, and functionalization of biominerals such as sea urchin bone. We studied on improvements of functions of hydroxyapatite/collagen nanocomposite such as coating on metals, self -setting paste and antimicrobial properties. Further, we research on phosphatized sea urchin bone for artificial bone and toxic ion removing materials.


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

Cooperation Profile

Biodegradable Bone Paste
Combination of the hydroxyapatite/collagen bone-like nanocomposite (HAp/Col) and silane coupling agent.
The HAp/Col paste was substituted with new bone by bone remodeling process in three months after injection.

Removing fluoride ions from waste water utilizing sea urchin bone
Calcium carbonate-calcium phosphate (C-P) composites were synthesized by soaking in orthophosphoric acid solution.
The C-P composite removed F– ion efficiently without severe leaching of phosphate ions.
After the F– removal, the C-P composites automatically separated into FAp and calcite. Thus, recycle of these resources become easier.
The C-P composites after F– removal has higher F– removal and sedimental ability than the conventional CaF2 method.
