Super biofunctional materials

Super biofunctional materials

To maintain their sophisticated vital activities, living organisms precisely control diverse biomolecules that perform various higher-order functions. Among these biomolecules, proteins are the molecules that perform the most diverse and sophisticated functions. To ensure maximum utilization of the functional abilities of proteins, human beings should aim to create novel proteins with functions that exceed natural biological functions by employing actively modifying natural proteins or designing new protein molecules. Using this process of "Super Biofunctional Material Engineering," we have created various novel functional materials by making full use of our original fusion protein constructing techniques. The main targets of these functional materials are control of cellular functions and biosensing. Applying to tissue engineering and regenerative medicine, we have developed various super biofunctional protein materials produced by modifying or designing growth factors, transcription factors, and extracellular matrices. Further, we designed molecular materials and systems and used these systems to perform pioneering research and development in the fields of ultrasensitive biosensing systems, intermolecular-interaction analysis, molecular detection in living cells, etc.
