Advanced Antibacterial Dressings for Chronic Ulcers: Alginate-Collagen-Cotton Hydrogel Composites Functionalized with Green CuO Nanoparticles
Background: Chronic ulcers are a major healthcare challenge due to their prolonged course, recurrence, persistent microbial colonization, and impaired tissue repair. This study developed sodium alginate–collagen hydrogel dressings reinforced with cotton fabric and functionalized with green-synthesized copper oxide nano...
