Zwitterionic polymers are currently in the focus of interest for preparing non-toxic and highly biocompatible low-fouling surfaces. After a concise introduction to strategies for preparing zwitterionic surfaces, recent efforts are presented for diversifying the structure of zwitterionic monomers and polymers, which has been quite limited up to now and is considered to be a bottleneck. Key structural variables are identified, and their influences on essential properties such as overall hydrophilicity and long-term stability are considered. Finally, promising targets for new variants are discussed.
