Photocrosslinkable Gelatin

Scaffolds for Tissue Engineering / Hydrogels

Trans-4-nitrocinnamate (NC) pendant groups were covalently linked to gelatin (Gel) via amide bonding through gelatin’s primary amino groups. Upon 365 nm UV light irradiation on Gel-NC aqueous solutions, insoluble gelatin hydrogels were formed as a result of fast [2+2] photocycloaddition of the NC groups. This photocrosslinking approach together with reverse emulsification was utilized to prepare micro-sized gelatin hydrogels. Gel-NC and its hydrogels had low toxicity to human neonatal fibroblast cells.
