Zwitterionic or biocompatible polymers with improved properties are described for use in cell encapsulation, device coating, or combinations thereof. The biocompatible polymer contains a zwitterionic monomer, a monomer with reactive side chains, and optionally another hydrophobic monomer or neutral hydrophilic monomer. The zwitterionic polymers are cross-linked via covalent bonds with cross-linking agents to form zwitterionic hydrogels in the presence of cells. Methods of making and using the zwitterionic polymers are also provided. |
