The surface modification of implantable biomaterials with zwitterionic phosphorylcholine polymer is demonstrated through mussel-mimetic catecholamine polymer thin films. Using this method, the surfaces of alginate hydrogel microspheres and polystyrene microbeads, a model material known to produce robust foreign body responses and fibrosis, are successfully modified to reduce the tissue reaction by reducing the fibrosis in immunocompetent C57BL/6J mice.
通过模仿贻贝的儿茶酚胺聚合物薄膜,展示了用两性离子磷酸胆碱聚合物对可植入生物材料进行表面改性。使用这种方法,藻酸盐水凝胶微球和聚苯乙烯微珠(一种已知会产生强烈异物反应和纤维化的模型材料)的表面被成功改性,以通过减少免疫活性C57BL/6J小鼠的纤维化来降低组织反应。
