Gelatin methacrylate/carboxybetaine methacrylate hydrogels with tunable crosslinking for controlled drug release

In this work, methacrylated gelatin (GelMA) based hydrogels were fabricated with carboxybetaine methacrylate (CBMA) to manipulate the properties of the gelatin-based hydrogels, since CBMA is a much smaller compound compared to gelatin.
