Used in biomedical applications as a zwitterionic monomer for creating biocompatible coatings and hydrogels. Its unique structure enhances resistance to protein adsorption and cell adhesion, making it ideal for medical devices such as contact lenses, implants, and biosensors. Frequently copolymerized in surface modification to reduce biofouling and improve durability in physiological environments. Also applied in drug delivery systems due to its stability and low toxicity in aqueous media.
