Functional Materials Chemistry Lab
Machine-translated · View original
A lab that creates new medical materials compatible with the body, using ceramics and organic–inorganic hybrids.

AboutAbout the lab
Materials in harmony with living bodies and the environment.
The Ohtsuki Lab researches the creation of new functional materials that are in harmony with living bodies and the environment.
Its research targets are ceramics, organic–inorganic hybrids, biomaterials, and biomimetics.
The lab works on developing synthesis methods for medical ceramics such as artificial bone, and for materials inspired by how living organisms work.
It also studies the functions that materials show when the process of crystal formation is finely controlled.
Key terms
- Organic–inorganic hybrid
- A material that combines organic substances such as plastics with inorganic substances such as ceramics at the molecular or nanometer scale
- Biomaterial
- A material made for use inside the body, such as artificial bone or artificial joints
- Biomimetics
- An approach to creating materials and technologies by imitating the structures of living organisms and the ways they produce substances
- Simulated body fluid
- An aqueous solution containing ions at nearly the same concentrations as the liquid component of human blood. It is used to test outside the body whether a material will bond to bone

ResearchResearch themes
Targeting ceramics, organic–inorganic hybrids, biomaterials, and biomimetics, the lab aims to create new functional materials that are in harmony with living bodies and the environment. It works on medical ceramics, materials synthesis processes inspired by living organisms, nanostructure fabrication using interactions between organic and inorganic components, and precise control of crystal formation.
*Illustrative imageHow ceramics bond to bone
From the viewpoint of materials chemistry, the lab investigates how “bioactive ceramics”, which can bond directly to bone inside the body, work. It examines the mechanism by which a bone-like apatite layer forms on their surface, using tests in simulated body fluid.
*Illustrative imageOrganic–inorganic hybrids that bond to bone
The lab designs materials that combine, at the nanoscale, the inorganic and organic components needed for bonding to bone, giving them functions that bioactive ceramics alone cannot provide. The aim is materials that combine excellent mechanical properties with the ability to bond to bone.
*Illustrative imageBiomaterials with designed structures
The lab develops porous calcium phosphate ceramics whose resorption rate in the body can be adjusted by controlling pore size, shape, and amount. It also advances material design inspired by the forms and functions of living organisms.
