A Supramolecular Hydrogel Inspired by Elastin

Self‐assembly prevails in nature and learning from nature will lead to biofunctional materials. Inspired by the protein of elastin, we reported in this study on a supramolecular hydrogel bearing the elastin repeating peptide of VPGAG. The visco‐elasticity property, morphology of the nanostructures, and aromatic stacking in the self‐assembled nanostructure were characterized by a rheometry, transmission electron microscope (TEM), and fluorescence microscope, respectively. The biocompatibility of the gelator was also proved by an MTT assay. Though the supramolecular hydrogel failed to exhibit a high elasticity like elastin, the thixotropic hydrogel might have potentials for the applications in fields of cell culture, controlled‐drug release, etc.
