39Functional Polymer ScienceYoshiro OgomaAssociate ProfessorUtilizing biological materials in engineering to create biosensors and new materialsDepartment of Chemistry and MaterialsI am working to develop a biosensor capable of easily identifying the appropriate amount of medicine to administer by affixing CYP, which plays a central role in the liver, to an electrode. Diatoms, a type of phytoplankton, use a protein called silaffin to form their silica shells. My lab has succeeded in using a polymer that imitates that structure to create new silica materials in numerous forms.Associate Professor Ogoma received his Doctorate of Science at Tohoku University after completing the textile research course at Shinshu University Graduate School. He took his current position in 1999. From 2001 to 2002, he studied at the University of Cologne in Germany as an exchange student. His specialty is biopolymer engineering.By recombining countless biological molecules to apply biological materials to engineering, it becomes possible to develop new materials based on new principles.Outlook for researchAlthough many graduates are employed in the areas of chemical materials and medical equipment, I strive to give them an education that can be applied to companies in all elds.Outlook for students after graduationFormation of silica in numerous shapes by adding polymers (an example use in new materials)A CYP immobilized electrode that demonstrates a dierent electrical current and voltage response depending on the type of chemical (an example use as a biosensor)-1.00E-07-5.00E-080.00E+005.00E-081.00E-07-0.7-0.5-0.3-0.10.1Current(A)Potential(V)基質なしリドカインテストステロンニフェジピンlidocainesubstrate-freetestosteronenifedipineFunctional Polymer ScienceNecklace-shaped supramolecules and cellulose/chitin nano-whiskersDepartment of Chemistry and MaterialsI am pursuing two principal areas of research. The first involves utilization of necklace-shaped supramolecules called polyrotaxanes in order to develop functional materials such as gels, fibers, and films through chemical modification. The second involves applications of nano-whiskers, that is, rod-like microcrystal particles of cellulose obtained primarily from trees and plants and those of chitin from crab and shrimp shells for use as reinforced nanocomposites.Jun ArakiAssociate ProfessorAssociate Professor Araki took his current position in 2012 after working as a JST-CREST postdoc researcher, a technical advisor to Advanced Softmaterials Inc., and an assistant professor under the Shinshu University Young Researchers Empowerment Project. His areas of specialization include supramolecular chemistry and polysaccharide chemistry.Polyrotaxane and cellulose/chitin nano-whiskers are both materials with diverse future potential. These carbohydrate-based, eco-friendly, and biodegradable components will nd wide application in society.Outlook for researchGraduates are employed primarily by chemical and material manufacturers.Outlook for students after graduationA certain polyrotaxane derivative, that is, a nano-sized necklace molecule with a width of 1 nanometer, can be used to form a exible lm that has been utilized to paint cell phones.Cellulose nano-whiskers from plants (left). These nano-sized bers have an elastic modulus higher than that of steel. They can form a liquid crystal that shows vivid birefringence between crossed polarizers (right).
