We develop functional biomaterials that can treat intractable diseases based on multidisciplinary fields such as polymer science, biomaterials, drug delivery system (DDS), and regenerative medicine. In recent years, advanced medical technologies have been developed implementing new therapies including gene therapy and regenerative medicine for improved treatment. However, even with the cutting-edge technology treatment, they still have many problems such as severe side effects, insufficient efficacy, drug resistance, low patient compliance, etc. Biomaterials are expected to play an increasingly important role in the development of advanced medical technology, which enables the treatment of intractable or incurable diseases in the future. We have been developing innovative functional biomaterials to improve the limits of the current modern therapy having international collaboration with various research groups in Singapore, South Korea and the United States, and promoting our research toward clinical application and commercialization.
