| Outline of Final Research Achievements |
We studied the fundamental research of Layer-by-Layer (LbL) technique which employed weak polymer-polymer interactions, and created the polymeric materials made by LbL method. We demonstrated that the stereocomplexes prepared by LbL of stereoregular polymers showed high thermal stability, mechanical strength, and so on. On the other hand, we successfully fabricated the 3D tissues by coating extracellular matrix (ECM) nanofilms onto cell surfaces using LbL assembly. Moreover, our method could introduce blood vessel structures into tissues. By using these techniques, we could fabricate cancer models, cardiac tissues, skin models and revealed that these tissues would be useful for pharmaceutical applications and regenerative medicine. We also created the dental materials and novel vaccine systems. These results clearly demonstrated that fundamental researches of chemistry and polymer chemistry created a new field in biomedical area, and could provide novel approaches to the medical field.
