Polyacrylate glue protein analogs of the glue secreted by Phragmatopoma californica, a marine po
synthesized with phosphate, primary amine, and catechol sidechains with molar ratios similar to th
proteins. Aqueous mixtures of the mimetic polyelectrolytes condensed into liquid complex coacerv
neutral pH. Wet cortical bone specimens bonded with the coacervates, oxidatively crosslinked thro
sidechains, had bond strengths nearly 40% of the strength of a commercial cyanoacrylate. The uniq
properties of complex coacervates may be ideal for development of clinically useful adhesives and
biomaterials.
