Used as a non-ionic, water-soluble polymer in biomedical and pharmaceutical applications due to its excellent biocompatibility and low toxicity. Commonly employed as a protein conjugate to enhance drug stability and circulation time, similar to PEGylation. Applied in drug delivery systems to improve solubility and reduce immunogenicity of therapeutic agents. Utilized in coatings for medical devices to create anti-fouling surfaces that resist protein adsorption and bacterial adhesion. Also explored in tissue engineering and hydrogel formulations for its tunable physical properties and biocompatibility.
