Multifunctional chito-oligosaccharide-and deferoxamine-modified GelMA-OHA hydrogel dressing with antibacterial, antioxidant, and pro-angiogenic activities for infected wound healing
Infected wounds resist healing due to multidrug-resistant bacterial colonization and persistent inflammation, which render conventional antibiotic therapies largely ineffective. Consequently, non-antibiotic strategies that coordinate infection control with tissue regeneration are urgently required. We design a dual-cro...
