Overview of Research

My dream is to realize artificial functional soft materials that exceed the functions of living tissues.
Living tissues, which are soft and wet, can be classified as “gel materials” and show various excellent functions. On the other hand, artificial gel materials do not show such functions although they are also soft and wet materials like living tissues. To create artificial functional gels, I am trying to understand essence of gels, which has been studied for a long time but not understood yet. Also, I am trying to create various tough and functional gels based on the understood essence.
I have created muscle-like self-growing gels inspired by metabolism., anisotropic hydrogels based on lipid bilayer, and extremely tough gels based on alignment of the components.



Gels can show unlimited functions beyond imagination by combination with other molecules and materials. Touch our gels and feel their amazing properties and possibilities!
