Biologically inspired self-healing structural color hydrogels were developed by filling glucose oxidase (GOX) and catalase (CAT) additived glutaraldehyde cross-linked bovine serum albumin (BSA) hydrogel into methacrylated gelatin (GelMA) inverse opal scaffolds . The composite hydrogel materials with the polymerized GelMA scaffold could maintain the stability of an inverse opal structure and its resultant structural colors, whereas the protein hydrogel filler could impart self-healing capability through the reversible covalent attachment of glutaraldehyde to lysine residues of BSA and enzyme additives2. We have demonstrated that a series of unprecedented structural color materials with 1D linear structures, 2D patterns and 3D counterfeit-prevention objects and photonic path structures could be created by assembling and healing the hybrid hydrogel elements. In addition, the biocompatibility and biological applicability of the GelMA and proteins hybrid structural color hydrogels were also demonstrated. These features of the self-healing structural color hydrogels indicated their versatile values in different areas.
