Poly(ethylene glycol) diacrylate (MW 700)

Poly(ethylene glycol) diacrylate (MW 700) and cellulose nanofibers (CNF) jointly form a hydrogel scaffold. When the thickness of the scaffold reaches 0.4 mm, its surface is rich in micropores and the pore diameters are mostly between 20 and 50 μm, which is suitable for cell attachment^[2].

Product Properties:
This product is readily soluble in water and can be prepared into hydrogel precursor solutions of varying concentrations. Adding the photoinitiator LAP (HY-44076) to this precursor solution triggers crosslinking upon illumination, yielding a hydrogel with a certain mechanical strength.
Instructions:
1. Dissolve this product at a concentration of 10-20 (w/w)% in pure water or phosphate buffer at room temperature, depending on the intended use. Add 0.1-0.3% (w/w)% LAP photoinitiator to prepare a gel precursor solution.
2. Add the above solution to the mold and refrigerate. Irradiation under 405 nm light for 30-60 seconds will form PEGDA hydrogel.
