Polyacrylate glue protein analogs of the glue secreted by Phragmatopoma californica, a marine polycheate, were synthesized with phosphate, primary amine, and catechol sidechains with molar ratios similar to the natural glue proteins. Aqueous mixtures of the mimetic polyelectrolytes condensed into liquid complex coacervates around neutral pH. Wet cortical bone specimens bonded with the coacervates, oxidatively crosslinked through catechol sidechains, had bond strengths nearly 40% of the strength of a commercial cyanoacrylate. The unique material properties of complex coacervates may be ideal for development of clinically useful adhesives and other biomaterials.
加利福尼亚管栖蠕虫(一种海洋多毛纲动物)分泌的胶水的聚丙烯酸酯类胶水蛋白类似物,是通过磷酸盐、伯胺和儿茶酚侧链合成的,其摩尔比与天然胶水蛋白相似。模拟聚电解质的水性混合物在接近中性的pH值下凝聚成液体复合凝聚层。用凝聚层粘结的湿皮质骨标本,通过儿茶酚侧链进行氧化交联,其粘结强度接近市售氰基丙烯酸酯强度的40%。复合凝聚层独特的材料特性可能非常适合开发临床上有用的粘合剂和其他生物材料。
