Our lab aims to develop and improve the properties of biomaterials based on a detailed understanding of biological systems. Genetic or molecular engineering of biopolymers facilitates the flow of biological evolution and enables the amplification of specific abilities. Re-designing biomolecules for changing the affinity of antibodies, controlling the self-assembly of biopolymers for physically/mechanically robust biomaterials, and hybrid organic-inorganic materials for reinforced materials are good examples. The research on tuning the function and properties of biomaterials for specific purposes will solve the problems faced by humankind in medical, pharmaceutical, agricultural, and environmental fields.
