The objectives of our research group are to understand molecular-level interactions between biological systems and external signals, to control the interactions by synthetic molecules, and to develop new artificial materials on the basis of the interactions. Especially, our group wants to develop key molecular modules for efficient penetration into biosystems, for selective response to physical, chemical, or biological signals, and for escape from severe toxicity or foreign body reactions. We wants to combine the key molecular modules for overcoming the current limitations of biomaterials in clinical applications.
