Development of materials, analytical methods, and treatments based on biomolecules


There are various types of living organisms, including humans, and each has various functions. Living organisms also produce macromolecules such as proteins and polysaccharides, which can be utilized as analytical, environmentally recyclable, and medical materials. Our laboratory develops materials, analytical methods, and therapeutic methods to solve various problems based on bacteria, cells, and the proteins, polysaccharides, and other biomolecules they produce. Recently, global warming caused by greenhouse gases from human social activities, abnormal weather, and environmental destruction caused by macroplastics have become major problems, and we hope to develop basic technologies to solve these problems.


Information

Start of the new fiscal year!

Publicationaward

D3 Kugo's paper has been published in Polymer Journal (IF=2.8). We have succeeded in improving the crystallinity of cellulose type II by about 20% by performing multiple dilute alkali post-treatments. This method makes it possible to prepare highly crystalline cellulose type II and is expected to lead to the development of cellulose type II materials with high mechanical strength.

Publicationaward

The results of joint research with the Macromolecular Chemistry Laboratory have been published in ACS Macro Letters with Dr. Mizukami as the first author (IF=5.8). Polysaccharides with various structures can be synthesized by ring-opening polymerization using monomers derived from cellulose, which exists in large quantities as a renewable resource. The polysaccharides can be chemically recycled by depolymerization, and are expected to contribute to the circular economy.

Publicationaward

D3 Kugo's paper has been published in Carbohydrate Polymers (IF=11.2). We succeeded in clarifying the mechanism of crystal transition from cellulose type I to type II in low-temperature dilute alkali treatment. It is suggested that the crystal transition can be controlled by adjusting the treatment conditions of low-temperature dilute alkali treatment, and the creation of new cellulose materials consisting of cellulose type I and II is expected by using this method.
