Widely used as a zwitterionic monomer in the synthesis of smart polymers and responsive hydrogels, this compound contributes to biocompatible and antifouling surfaces. Its sulfobetaine structure provides excellent water solubility and resistance to protein adsorption, making it ideal for biomedical applications such as drug delivery systems, contact lenses, and coatings for medical devices. It is also employed in surface modification of nanoparticles and membranes to enhance stability and reduce nonspecific binding in biological environments. Additionally, it participates in copolymerization processes to create materials with tunable properties for use in biosensors and tissue engineering scaffolds.
