Background: A number of natural and synthetic polymers were subjected to functionalization with catechol-containing modifiers, mimicking the chemical structure of Mytilus foot proteins of marine mussel, and affording materials with specific properties that are related to their adhesion ability. Objective: This review highlights the various applications of mussel-inspired polymers, worked out within the last five years, in separation processes, hydrogels making, and biomedicals. Method and Results: Marine mussel-inspired polymers were fashioned either by direct synthesis from catechol-containing monomers or chemical modification of existing polymers. Mostly, the catechol units attached to the polymer matrixes are 3,4-dihydroxyphenyl-L-alanine and dopamine. Conclusion: Michael addition and/or Schiff base reaction between catechol-containing molecules units and polyamines afford efficient separative membranes. Hydrogel-making from catecholcontaining polymers can be easily realized via oxidation with oxidants and coordination with transition metal ions.
