Poly(ethylene glycol) diacrylate is widely used in the development of hydrogels for biomedical applications, such as drug delivery systems and tissue engineering scaffolds. Its ability to form crosslinked networks makes it suitable for creating materials with controlled porosity and mechanical properties. In drug delivery, it allows for the sustained release of therapeutic agents, enhancing treatment efficacy. Additionally, it is utilized in 3D bioprinting to fabricate complex structures that mimic natural tissues. In the field of photolithography, it serves as a key component in the production of microfluidic devices and sensors. Its biocompatibility and tunable properties also make it valuable in wound healing applications, where it can be incorporated into dressings to promote tissue regeneration. Furthermore, it is employed in the development of contact lenses and other ophthalmic products due to its water retention and comfort-enhancing characteristics.
