Zwitterionic polymers have anion and hydrated and render them unique biocompatibility. cation groups simultaneously, which make them highly Because of their unique zwitterionic pendant-side chain structures, sulfobetaine methacrylate （SBMA） polymers present the excellent anti-biofouling properties, i.e. the resistance to protein adsorption, the inhibition of bacterial and blood coagulation, which make them increasingly applied in a wide range of biological and medical related fields recently. The hydration theory, one of the widely accepted antifouling mechanisms, is briefly introduced. In this article, recent progress in the properties, synthesis methods and surface construction methods is reviewed, the applications of SBMA polymers in the materials for artificial organs, tissue engineering, biological separation, bio-rnonitoring system and temperature-sensitive materials are summarized. In addition, SBMA polymers holding great potential for use in biomaterials and issues existed in these applications are also discussed.
