Used in the production of soft contact lenses due to its high water content and biocompatibility, making it comfortable for extended wear. It is also applied in drug delivery systems, where its hydrogel properties allow for controlled release of medications. In medical devices, it serves as a coating to improve biocompatibility and reduce irritation. Additionally, it is utilized in tissue engineering scaffolds to support cell growth and regeneration. Its hydrophilic nature makes it suitable for use in wound dressings, promoting moisture retention and healing.
