Biofiber Science Lab
Machine-translated · View original
The lab studies biomass materials such as cellulose, aiming to understand them, control them, and put them to use in new materials.
AboutAbout the lab
Understanding, controlling, and using biomass materials
The Biofiber Science Lab investigates the solid-state structures, physical properties, and distinctive phenomena of various polysaccharides, centered on cellulose.
Based on fundamental knowledge of structure and properties, the lab also works on developing highly functional materials.
Undergraduate students join the lab in their fourth year (graduate school: Division of Forest Science, Graduate School of Agriculture).
Key terms
- Polysaccharide
- A large molecule made of many sugars, such as glucose, linked together. Examples include cellulose and chitin.
- X-ray diffraction
- A method that shines X-rays on a substance and examines the arrangement of its atoms and molecules from the pattern in which the X-rays are diffracted.
- Hydrogel
- A jelly-like solid that contains a large amount of water.

ResearchResearch themes
The lab investigates the solid-state structures and physical properties of polysaccharides, centered on cellulose, and aims to develop highly functional materials based on that knowledge.
*Illustrative imageUnderstanding the structure of biomass materials
The lab examines the structures of polysaccharides and wood, from the solid state to the dissolved state, using X-ray diffraction, NMR, MRI, and microscopy. It also studies data analysis methods, aiming to understand complex structures through new techniques such as image analysis.
*Illustrative imageControlling structure with magnetic fields and gels
The lab studies methods that align polysaccharides by applying a magnetic field, and methods for making hydrogels with nanosized pores. It evaluates the properties of the resulting materials, aiming to understand the relationship between structure and properties.
*Illustrative imageMaking highly functional materials
Drawing on its understanding of structure and its techniques for controlling it, the lab aims to develop films whose strength differs by direction and materials that adsorb substances in nanosized pores. It also uses as raw materials polysaccharides that do not exist in nature and are synthesized through the action of enzymes.
