Poly(ethylene glycol) dimethacrylate is widely used in the development of hydrogels for biomedical applications due to its biocompatibility and ability to form crosslinked networks. It serves as a key component in drug delivery systems, enabling controlled release of therapeutic agents. In tissue engineering, it is utilized to create scaffolds that mimic the extracellular matrix, promoting cell growth and tissue regeneration. Additionally, it is employed in the fabrication of contact lenses and other ophthalmic devices, providing flexibility and moisture retention. Its use in photopolymerization processes also makes it valuable in 3D printing and microfabrication for creating precise, complex structures.
