Description

Gelatin Methacryloyl (GelMA) is a photocrosslinkable derivative of gelatin, a natural macromolecule containing RGD cell‑adhesion motifs and enzyme‑degradable sites that support cell attachment, proliferation, and differentiation. Through methacryloyl (MA) modification, gelatin gains light‑induced crosslinking capability and can be rapidly cured into hydrogels under UV or visible light in the presence of a photoinitiator. GelMA hydrogels retain the excellent biocompatibility, biodegradability, and cell affinity of native gelatin while offering far greater structural stability and mechanical strength than thermosensitive gelatin gels, making them highly suitable for 3D scaffold fabrication and widely used in cell 3D culture, tissue engineering, and bio‑3D printing.

Our GelMA is compatible with a range of photosensitive polymers containing vinyl or o‑nitrobenzyl (NB) groups, such as PEGNB, HANB, HAMA, CMCMA, and PEGDA. Under light exposure, these components undergo rapid polymerization and crosslinking to form high‑strength hydrogels within seconds, providing users with flexible and tunable material solutions for advanced biofabrication.
