Zwitterionic polymers or biocompatible polymers with improved properties for cell encapsulation, coating of devices, or a combination thereof are described. The biocompatible polymer contains a zwitterionic monomer, a monomer with a reactive side chain, and optionally another hydrophobic monomer or a neutral hydrophilic monomer. The zwitterionic polymers are cross-linked with a cross-linker via covalent bond to form a zwitterionic hydrogel in the presence of cells. Also provided, are methods of making and using the zwitterionic polymers.
描述了具有改进性能的带有离子交换基团的聚合物或
生物相容性聚合物,用于细胞包埋、器件涂层或二者的组合。
生物相容性聚合物包含一个带有离子交换基团的单体、一个带有反应性侧链的单体,以及可选的另一个疏
水性单体或中性亲
水性单体。这些带有离子交换基团的聚合物通过共价键与
交联剂交联,形成存在细胞的带有离子交换基团的
水凝胶。还提供了制备和使用这些带有离子交换基团的聚合物的方法。
