HA-based materials cross-linked using reversible guest–host chemistry. The guest and host functional chemical groups bind to form a guest–host complex, which serves as a noncovalent cross-link. The guest–host cross-links are shear-thinning and rapidly self-healing, making this platform promising for minimally invasive injection for CNS applications.
