Photosensitive small intestinal submucosal hydrogels loaded with the KR-12-a5 peptide promote periodontal osteogenesis and antimicrobial activity

The IA/SIS/KR-12-a5 hydrogel exhibited rapid UV-induced gelation, strong mechanical properties, antibacterial efficacy, and significant osteogenic potential. These attributes suggest its suitability as an injectable biomaterial for bone regeneration and repair.
