Synthetic approaches inspired by mussel adhesion. a Schematic illustration of mussel adhesive protein-inspired mimetic polymer systems. Dopa or a catechol mimic of Dopa covalently coupled to polymer chain ends or as side chains of polymerizable catechol monomers. b Histological results from implantation of the PEG-catechol hydrogel into mice. c Images of tissue adhesives with adhesive properties that combine high strength. d Key features of mussel foot protein and its synthetic homolog. e Key features of natural and translated mussel adhesion. The figure b, d, e was reproduced/edited from References [31, 52, 54], respectively
