Effect of Photoinitiation Process on Photo-Crosslinking of Gelatin Methacryloyl Hydrogel Networks.

ABSTRACT: Gelatin methacryloyl (GelMA) has emerged as a widely utilized biomaterial in tissue engineering due to its tunable mechanical properties, cell-adhesive motifs, and photo-crosslinkability. However, the physicochemical characteristics and biomedical utility of GelMA hydrogels are greatly influenced by the choice and concentration of photoinitiating systems. Despite increasing acceptance of visible-light and UV-sensitive initiators, a systematic comparative evaluation of their impact on GelMA hydrogel properties has not been studied. In this study, we present the first systematic investigation of how individual photoinitiators, Eosin Y (EY), Lithium Phenyl-2,4,6-trimethylbenzoylphosphinate (LAP), Ruthenium (II) trisbipyridyl chloride ([RuII(bpy)₃]²⁺) (Ru), affect the vis
