제목 pH-Tunable Supramolecular Networks Formed by Double-Axle Inclusion for Advanced Biomatierials
초록 We report on supramolecular networks assembled by a unique system, named double-axle intrusion (DI) system, using gamma-cyclodextrin and the linear block copolymers grafted onto dextran, which can modulate rheological properties in response to pH changes. The supramolecular network induced drastic changes in the rheological properties in response to pH variation. Our knowledge based on supramolecular research demonstrates that such macroscopically rheological changes are results of molecularly mechanical actuations of the DI system in supramolecular networks. As a result, the molecular mobility allows to modulating the length of cross-linked part in polymeric network under pH changes. It is expected that our pH-tunable supramolecular network system can be utilized to achieve advanced functional biomaterials such as smart hydrogels and drug carriers.
