Description and Uses

Poly(ethylene glycol) diacrylate (PEGDA) is a blank slate hydrogel that gels rapidly at room temperature in the presence of a photoinitiator and light. PEGDA hydrogels are potent tools for uncovering basic cellular biology because they are considered biologically inert (“blank slate”), and their mechanical properties can be varied over an extensive range of moduli.PEGDA is an emerging scaffold for tissue engineering and regenerative medicine since polymerization can occur rapidly at room temperature, requires low energy input, has high water content, is elastic, and can be customized to include a variety of biological molecules.

PEGDA is used in dental compounds, offset inks, varnishes and flexible coatings.
