Stable self-healing hydrogel

Inspired by the wound healing properties of animals, researchers developed a self-healing hydrogel with stable structural color by filling a honeycomb-shaped inverse opal scaffold composed of a methacrylated gelatin hydrogel with a healable protein hydrogel, and created structured color materials by assembling the composite hydrogel. - Read at PNAS
