Poly(ethylene glycol) diacrylate is widely used in the biomedical field for creating hydrogels, which are essential for drug delivery systems, tissue engineering, and wound healing. Its ability to form cross-linked networks makes it suitable for encapsulating cells and drugs, providing controlled release and biocompatibility. In the field of 3D printing, it serves as a key component in bioinks, enabling the fabrication of complex, cell-laden structures. Additionally, it is employed in the development of contact lenses and other medical devices due to its water retention and softness properties. In industrial applications, it is used as a cross-linking agent in coatings, adhesives, and sealants, enhancing durability and flexibility.
