Outline Activities
Structural polysaccharides such as cellulose, the skeletal framework of wood cell walls, are not just macromolecules, but have unique nanostructures built in a hierarchical manner during biosynthesis. The only-one features of living organisms and biomaterials, accumulated in a bottom-up manner through their biological activities, are the secrets of nature, which will probably be impossible to synthesize in an artificial way. These nanostructures, realized by the regular arrangement of simple molecules, are ubiquitous in nature, and are very attractive as a stage for creating new materials. I am fascinated by "cellulose nanofibers", the ultrafine nanofibers that support giant trees, and I have devoted myself to research in the biomedical and cosmetic fields to explore the "unknown functions" inspired by the nanostructures of natural polysaccharides.
(1) Development of xeno-free (animal components-free) biomaterials for regenerative medicine
The cells that make up our bodies are surrounded by fibrous materials such as collagen and polysaccharides with regular structures. By focusing on the unique nanostructures of wood-derived nanofibers to mimic the in vivo cellular microenvironments, we are challenging the controlled culture of stem cells useful for xeno-free regenerative medicine (xeno-free: containing no components derived from other animal species to avoid the risk of immune rejection or infection).
(2) Development of immunoadjuvants to enhance the efficacy of vaccines against infectious diseases
Vaccines have played a crucial role in the fight against infectious diseases and cancer, but their susceptibility to the human body still remains an issue due to the personal immune variation. We have discovered that a novel Pickering emulsion using natural polysaccharide nanofibers as an emulsifier can significantly activate human immunity, and we are challenging to develop its function as an immunoadjuvant.
(3) Development of marine biodegradable wood-mimetic spherical microparticles for cosmetic applications
Marine biodegradability of materials is extremely important to solve the problem of marine pollution caused by microplastics. Plants and trees are safe and secure materials that have been biodegraded by marine microorganisms for 380 million years. Therefore, we are challenging to develop core-shell microparticles from wood components, and promoting the "Sea Forest Project" to develop new materials that can be biodegraded and capture carbon dioxide, a cause of global warming, in the ocean.

Educational
Educational Activities
Education takes the form of lectures and seminars ranging from basic to frontier research, as well as research mentoring, in which each student is assigned an individual topic. We strive to develop human resources who can independently formulate questions, solve problems, make decisions, and communicate their findings to the outside world. The program emphasizes the ability to multi-task, to establish multiple perspectives and directions, and multiple operations within oneself, rather than the traditional one-pointed focus and rush to the front, which is the image of the conventional researcher. To return research results to society, we actively apply for patents for applied research and cooperate with industry, academia and government. They also participate in supporting academic society activities and presenting topics at symposia.
