Poly(ethylene glycol) diacrylate is widely used in the development of hydrogels for biomedical applications due to its biocompatibility and ability to form cross-linked networks. It is employed in drug delivery systems, where it helps control the release of therapeutic agents over time. In tissue engineering, it serves as a scaffold material to support cell growth and tissue regeneration. Additionally, it is utilized in the fabrication of contact lenses and wound dressings, providing a moist environment that promotes healing. Its photo-polymerizable nature makes it suitable for 3D printing and microfabrication in creating precise medical devices and implants.
