We foster researchers and engineers who lead the new era by exploring new aspects in the fields of material science and engineering of biobased materials, core materials in this century.
We foster researchers and engineers who play a leading role in the new era by exploring new aspects in the fields of material science and engineering of biobased materials, which will serve as core materials in this century. Biobased materials are defined as materials produced through a new process using the raw materials of plants and other renewable biomass resources. The following points are essential for exploration:
1. The understanding and effective use of biological resources, especially microbes and plants, as raw materials;
2. Methods for developing raw materials into practicable materials through chemical and biological control;
3. Methods for clarifying material properties, especially correlations between fine structures and functional expressions, and for reflecting this in material development; and
4. Technology for processing biobased materials into fiber, plastic, and other products
We are engaged in research and education not only in fundamental fields, such as organic chemistry, physical chemistry, polymer chemistry and physics, but also in a wide variety of interdisciplinary fields, such as environmentally-related chemistry, bio-related chemistry, material chemistry, fiber science, process engineering, functional biology, bio processing, bioscience, applied microbiology, bio molecule science, nano material science, and nano bioscience.
By offering courses in these fields, we can foster human resources who are equipped with a comprehensive understanding of a wide range of academic fields.

|Our laboratory is oriented toward research in the longitudinal areas of organic and biological chemistry.|
It goes without saying that each faculty member has a high level of expertise in their respective field. By venturing into research in other fields, they make new discoveries.
Our aim is to contribute to environmental issues and medicine at the global level.
Presently, we convert biomass into molecules that can be synthesized organically through the power of microorganisms. Using those molecules, we then research polymer synthesis as it applies to environmental problems and medical treatment.
In order to promote this type of budding research, students as well as faculty must study and work in a range of sciences.
Research themes: Production process for bio-based materials, Screening of microbes producing bio-vinyl monomers and its application to development of novel medical polymers, Synthesis of functional organic materials and biomolecule conjugates
Keywords: Microbial production/ Process engineering/Synthetic chemistry/Polymer chemistry
|Our laboratory conducts basic and applied research to synthesize practical bio-based materials using ingredients from biomass. In our research, we develop new synthetic methods (chemo/bio-conversion) for existing bio-based materials such as polylactic acid, design and synthesize molecules for new bio-based materials, and evaluate their properties and functions. We also create new plastics using natural polymers such as polysaccharides and DNA. It is our hope that our daily research efforts will contribute not only to replacing existing plastics, but also to establishing new areas of material science and engineering research to achieve a paradigm shift in materials in this century.

|We identify the relationships between the structures and functions of biomaterials such as polysaccharides and proteins in solution and gels, using X-ray measurement and molecular modeling methods. We also develop materials using cellulose nanofibers. Our results are used in applied research and the development of new fiber and functional materials. We also look at dyeing and functional processing of hair and fiber using bio-based materials. The properties of bio-based materials, such as sustainable availability, low environmental impact, and high safety, are important factors for materials expected to come into wide use. We also continue to examine the properties unique to certain materials with the purpose of developing materials that take advantage of those properties.

|We focus on processing all kinds of bio or biobased polymeric materials using advanced biofabrication methods for medical and clinical applications. According to the requirements of final products, biopolymers (carbohydrate, DNA, protein etc.) and biobased polymers (chemically and microbially synthesized polymers) will be fabricated into functionalized films, fibers, stent, tissues, 3D scaffolds, etc. using the manufacturing technologies of electrospinning writing, electrospinning, electro-centrifugal spinning and bioprinting. To understand and to control the polymer manufacturing, the physical and chemical properties of the processed polymers, as well as the polymer forming mechanics will be systematically characterized and studied. Our promising research has attracted many international students worldwide. Why not join us?

|Properties of Nanomaterials|
|The research goal of our laboratory is to elucidate the relationship between static/dynamic nano-to-micro scale structures and properties of polymeric materials, especially biobased polymeric materials. We have investigated molecular aggregation structures (including ordered structures, amorphous structures and patterns) formed on polymeric materials in the solid state such as fibers and thin films of polymers or polymer alloys by using physicochemical techniques, spectroscopic methods and methods of scattering/diffraction of electromagnetic waves (X-rays (synchrotron X-rays), neutrons, visible lights). At the same time, we develop fabrication/design guidelines for new materials with the aim of generating unique properties. Elucidating the material properties of biobased polymers at the molecular level and developing structure evaluation technology for polymeric materials are areas of significant focus in our promotion of green innovation.
