| Outline of Final Research Achievements |
In the area of the endovascular treatment, the development and the clinical application have been widely used due to the high the therapeutic effect for cancer and tumor. In this research project, we have focused on supramolecular materials to apply the endovascular treatment. To prepare functional embolization materials, cyclodexterins (CDs) have been introduced into the supramolecular materials. By the introduction of CD molecules into the materials, we have successfully prepared the endovascular embolized supramolecular materials with drug delivery, self-healable, and high-elastic properties. Especially, self-healing and self-repairing materials formed by host-guest interactions recover to the initial strength even after the materials were cut in half, and then rejoined.
Moreover, we have prepared the high elastic supramolecular materials to show the reversible elastic deformation without breaking.
