Used in creating hydrogels for tissue engineering due to its ability to form cross-linked networks under mild conditions. The acrylamide groups allow for rapid photopolymerization when exposed to light in the presence of a photoinitiator, enabling precise control over gel formation. This makes it ideal for encapsulating cells and biomolecules without causing damage. Commonly applied in 3D cell culture systems, drug delivery matrices, and regenerative medicine scaffolds where biocompatibility and tunable mechanical properties are essential. Its multi-arm structure provides higher cross-linking density, resulting in improved stability and mechanical strength of the resulting gel.
