제목 Bio-inspired Oxygen-generating Gelatin Adhesives for Wound Management
초록 Mussel-inspired biopolymers have recently received considerable attention as tissue adhesives and sealants because of their strong adhesive strength in wet surfaces. Molecular oxygen (O2) has been implicated as an essential signaling molecule in the wound healing and tissue regeneration. Herein, we designed an O2-generating gelatin adhesive formed via calcium peroxide-mediated crosslinking reaction and in situ polymerization of dopamine. We demonstrate that the hydrogels rapidly generate O2 up to 70% pO2 and release O2 from hydrogels in a sustained manner (for up to 7 days in vitro). The hydrogels show controllable tissue adhesive strength (15−38 kPa) depending on dopamine concentrations. The hydrogels facilitate wound healing with enhanced neovascularization in vivo. These results suggest that the O2-generating tissue adhesive hold a great promise as tissue adhesives and sealants for wound management as well as tissue regenerative medicine.
