The lab draws out new functions from the nanostructures of polysaccharides derived from forests.

AboutAbout the lab
Discovering and using new functions from the structures that form life
The Bioresource Chemistry Lab studies the precise nanostructures of forest-derived polysaccharides and the interfacial functions that arise from them.
Using structural information on natural polysaccharides as a guide, the lab works on creating biomedical functions and developing cosmetic and agricultural materials.
The lab has a Biomedical Group and a Cosmetics and Agriculture Group, and a Frontier Group is in the planning stage.
On the lab's website, the lab is also introduced under the name 'Kitaoka Lab.'
Key terms
- Cellulose

The lab focuses on the precise nanostructures of forest-derived polysaccharides and the interfacial functions that arise from them, aiming to discover and use new functions. The Biomedical Group and the Cosmetics and Agriculture Group pursue the creation of biomedical functions and the development of cosmetic and agricultural materials.
*Illustrative imageMaterials for regenerative medicine and immune control
The lab regards the nanofiber form of natural structural polysaccharides, and the interfacial structure of regularly arranged sugar chains, as functions that act on living systems. It works on developing culture substrates for cells and tissues and active emulsions, which are challenges in regenerative medicine and immune control.
*Illustrative imageNanomaterials for cosmetics and agriculture
Focusing on properties of cellulose such as its ultrafine nanofiber form, structural regularity, and self-assembled crystals, the lab explores new functions of nanomaterials that make use of regular interfacial structures. It works on cosmetics, agricultural materials, and composites with lignin.
