Interactions between Biomolecules and Zwitterionic Moieties: A Review.

Throughout the past decade, zwitterionic moieties have gained attention as constituents of biocompatible materials for exhibiting superhydrophilic properties that prevent nonspecific protein adsorption. Researchers have been working to synthesize zwitterionic materials for diverse biomedical applications such as drug delivery, protein stabilization, and surface modification of implantable materials. These zwitterionic materials have been used in assorted architectures, including protein conjugates, surface coatings, nanoparticles, hydrogels, and liposomes.
