Fabrication and biological evaluation of a bioactive gelatin–sericin hydrogel for infected wound healing

, comparable to those of the gentamicin controls. Cytocompatibility was confirmed by >90% cell viability in MTT assays, and in vivo zebrafish models demonstrated significantly enhanced wound closure (72% by day 5) compared with untreated controls (38%). Collectively, these findings highlight the promising potential of GSH as a biocompatible, antimicrobial, and pro-healing hydrogel for wound management applications.
