A family of polysulfobetaines of novel architecture was synthesized. Different from the established design, the cationic and anionic groups of their zwitterionic moieties are located at equal distances from the backbone in these polymeric inner salts. Thin hydrogel films were prepared from the polymers and photo-cured. The coatings were studied with respect to their low-fouling capability in a set of in-vitro biofouling assays, covering proteins of different net charges as well as model marine organisms. All polyzwitterions were shown to minimize biofouling effectively. Their specific fouling resistance is controlled by the detailed chemical structure of the polyzwitterions, and reaches the performance of the benchmark polyzwitterion poly(3 (N (2 methacryloyloxyethyl)-N,N-dimethyl-ammonio)propanesulfonate).
