Clinical applications for thesematerials are expected to include uses inregenerative medicine.Outlook for students after graduationGraduates are primarily employed by materialand chemical manufacturers, although somework atinvolved in medicalequipment or pursue clinical applications suchas regenerative medicine.companiesAssociate ProfessorTERAMOTO AkiraAssociate ProfessorNIIHORI YoshikiDepartment ofChemistry and MaterialsDepartment ofChemistry and MaterialsAssociate Professor Teramoto tookhis current position in 2008 afterworking as a researcher at a privatedairy company and as a researchassociate and assistantprofessorin the Faculty of Textile Science andTechnology at Shinshu University.His areas of research include thedevelopment of substrates for cellfunctionalandculturingevaluation of cultured cells.Dr. Yoshiki Niihori received his Ph.D.in Science from Tokyo University ofScience in 2013. He conductedresearch on metal nanoclusters atRikkyo UniversityTokyoUniversity of Science. In 2025, hejoined Shinshu University. Hisexpertise lies in the synthesis ofnanomaterials and the explorationof their photophysicalproperties.B yn a n o c l u s t e rc o m p o s i t i o n a n d s t r u c t u r e , w e c a n t u n e t h e i rT h i sP h o t o p h y s i c a l p r o p e r t i e s .t h ee n a b l e sl i g h t - e m i t t i n g a n dd e v e l o p m e n t o f e f f i c i e n ta ne n e r g y - c o n v e r s i o nn a n o t e c h n o l o g yi n t e r d i s c i p l i n a r ya l s oi n c a t a l y s i s a n d m e d i c a ld r i v e sa c r o s sd e v i c e sc h e m i s t r y , p h y s i c s , m a t e r i a l s s c i e n c e , a n d l i f es t e ps c i e n c e s.

With strong technical andpresentation skills, our graduates are prepared to lead inboth academia and industry.Examples of Geometrical structures of ligand-protected metal nanoclusters(illustrated here: thiolate-protected gold clusters, Aun(SR)m)Blue upconversion emission observed from a solution sample (left) and asolid sample (right) containing platinum-doped silver nanoclusters and dyemolecules under 785 nm excitation.When metals are miniaturized to the nanoscale, they exhibit novelproperties not seen in bulk materials. “Nanoclusters” — structures madeof just a few atoms — can behave in surprising ways. For example, inertgold becomes catalytically active, or gains magnetic and luminescentproperties when clustered. Even a single-atom difference can drasticallyalter their behavior. We synthesize these nanoclusters with atomicprecision to reveal how their unique properties emerge. Our goal is todesign next-generation, high-performance nanomaterials.Osteoblasts from mice cultured on a non-woven material made from cellulose nanofibersTissue cells are cultured over a long period of time using a petri dis hwhose bottom is coated with the material we created, and then theyare kept in a device that maintains sanitary conditions so that we canexamine their functionality.A st h e f i r s td r i v e nThe body identifies artificial materials as foreign objects andattempts to eliminate them from the body and neutralizethinking of, andany harmful effects. Consequently,developing, new polymer materialsthat are morecompatible with living organisms are extremely importantsteps in the treatment of numerous diseases.theandDevelopment of Functional Polymeric Materials for Bio-ApplicationsNanocluster Engineering
