“…Apart from the examples presented previously, mussel-inspired derivatives of various biopolymers [116] have attracted attention for their potential as multifunctional materials. Amongst the various catechol-derivatised biopolymers, polysaccharides (e.g., alginate [117,118], chitosan [119][120][121][122][123], hyaluronic acid [124], fucoidan [125], heparin [126,127]) hold a prominent position due to their set of attractive properties (e.g., biocompatibility, antimicrobial action, drug delivery). Coupling chemistries have either used dopamine reacting with available carboxyl groups [117,118,[124][125][126][127], or 3,4-dihydroxyhydrocinnamic acid reacting with available amine groups [119][120][121][122][123] such as in the case of chitosan (Scheme 12).…”
