Current Research Topics

Nature is often giving us a hint to fabricate useful materials for human life, because biological organisms have a range of strategies to respond for diverse environments. Using the detail analyses by proteomic and molecular biological techniques, M Tanaka's group seeks how to produce novel bionanomaterials/molecules for nanotechnological and biomedical applications. Now we are focusing on the production of functional nano-wires using a bio-inspired process of membrane morphological regulation. In biological cells, from bacteria to human, the membranous structure is highly regulated by various proteins. The biological phenomenon has inspired the development of novel technology to capsulate different morphology of nanomaterials such as particles, rods, and nanowires within the biological membrane. Since these biofunctional materials capsulated in lipid membrane generally show high biocompatibility and dispersibility, now we are trying to apply these material for nanotechnological and biomedical applications.
