Synthesis of HA-based hydrogels via the covalent cross-linking of HA-AES and HASH. Fast thiol/acrylate Michael reaction contributes to the establishment of the primary network that is hydrolytically degradable. The disulfide crosslinks, formed gradually and spontaneously, stabilize the primary network, at the same time, introducing adaptable and dynamic features to the network to facilitate the 3D assembly of hS/PCs.
