Recent reports indicated that in addition to charge neutrality, the zwitterion's segmental dipole orientation is an important factor for interacting with the environment. Accordingly, a series of polysulfobetaines with a novel architecture was designed, in which the cationic and anionic groups of the zwitterionic moiety are placed at equal distances from the backbone. They were investigated by in vitro biofouling assays, covering proteins of different charges and model marine organisms. All polyzwitterion coatings reduced the fouling effectively compared to model polymer surfaces of poly(butyl methacrylate), with a nearly equally good performance as the reference polybetaine poly(3-(N-(2-(methacryloyloxy)ethyl)-N,N-dimethylammonio)propanesulfonate). The specific fouling resistance depended on the detailed chemical structure of the polyzwitterions. Still, while clearly affecting the performance, the precise dipole orientation of the sulfobetaine group in the polyzwitterions seems overall to be only of secondary importance for their antifouling behavior.}, language = {en} } @article{SchanzenbachPeter1997, author = {Schanzenbach, Dirk and Peter, Martin G.}, title = {NMR spectroscopy of chito-oligosaccharides}, year = {1997}, language = {en} } @article{SchanzenbachPeter1997, author = {Schanzenbach, Dirk and Peter, Martin G.}, title = {Chromatography of chito-oligosaccarides}, year = {1997}, language = {en} } @article{SchanzenbachMaternPeter1997, author = {Schanzenbach, Dirk and Matern, Christa-Maria and Peter, Martin G.}, title = {Cleavage of chitin by means of sulfurice acid/acetc anhydride and isolation of peracetylated chito- oligosaccharides}, year = {1997}, language = {en} } @article{SchanzenbachMaternPeter1997, author = {Schanzenbach, Dirk and Matern, Christa-Maria and Peter, Martin G.}, title = {Synthesis of glycosylamines and glycopeptides}, year = {1997}, language = {en} } @article{RottmannSynstadThieleetal.1999, author = {Rottmann, Antje and Synstad, Bjoenar and Thiele, G. and Schanzenbach, Dirk and Eijsink, Vincent G.
