Widely used in biomedical and pharmaceutical applications due to its biocompatibility and water solubility. It serves as a key monomer in synthesizing stimuli-responsive hydrogels for drug delivery systems, where controlled release is achieved in response to temperature or pH changes. Commonly employed in surface modification of nanoparticles and medical devices to enhance stability and reduce protein adsorption. Also utilized in fabricating contact lenses and wound dressings because of its non-toxic and moisturizing properties. In tissue engineering, it forms part of scaffolds that support cell growth. Its ability to form copolymers makes it valuable in creating advanced coatings with anti-fouling characteristics for biosensors and diagnostic equipment.
