Used as a non-ionic surfactant and stabilizer in pharmaceutical formulations, enhancing solubility and bioavailability of poorly water-soluble drugs. Commonly applied in drug delivery systems due to its biocompatibility and low toxicity. Employed in coatings for medical devices to reduce protein adsorption and improve hemocompatibility. Also utilized in tissue engineering scaffolds and hydrogels for controlled release applications. Shows promise in improving the stability of nanoparticles and liposomes in biomedical applications.
