Supramolecular hydrogels are rather weak but able to cause distinctive properties such as enhanced adaptability, high specificity, fast response, and good biocompatibility owing to their dynamic cross-linking nature. In this presentation, we exhibit the design of functional hydrogels on the basis of non-covalent yet interpenetrating polymeric networks. Both networks were formed by conformational change of natural polysaccharides and host-guest interaction between individual polymer chains that contain azobenzene or cyclodextrin moieties, and able to show macroscopic performance such as self-healing or injectable properties when interpenetrated. Furthermore, we could demonstrate the hydrogels as a responsive vector for programmed release of drug molecules or a smart bio-ink for patterning. |
