Double‐network Heparin Dynamic Hydrogels : Dynagels as Anti‐bacterial and 3D Cell Culture Scaffolds

Double cross-linked dynamic hydrogels-dynagels have been prepared through reversible imine bonds and supramolecular interactions, which showed good pH responsiveness, injectability, self-healing property and biocompatibility. With the further encapsulation of heparin, the obtained hydrogels exhibited good anti-bacterial activity and promotion effects for 3D cell culture.
