Gelatin methacryloyl

Gelatin methacryloyl (GelMA) is a modified form of gelatin that has been chemically functionalized with methacryloyl groups, allowing it to form a stable hydrogel when exposed to UV light and a photoinitiator. This methacrylic anhydride-modified gelatin is used as a base for 3D printing hydrogel bioinks, particularly for applications in tissue engineering, 3D bioprinting, and regenerative medicine.
