Abstract (original English)

Diabetic wounds, especially diabetic foot ulcers, pose a major global clinical challenge due to their slow healing and high infection susceptibility. Their typical pathological features include impaired angiogenesis, chronic hypoxia, persistent inflammation, oxidative stress, bacterial colonization, and neuropathy. Traditional treatment methods have limited efficacy, creating an urgent need for innovative therapeutic strategies. In recent years, biomaterials have emerged as a research focus in diabetic wound treatment, owing to their biocompatibility, versatility, and tissue regeneration potential. This article comprehensively reviews the pathological mechanisms of diabetic wounds. It also summarizes the application progress of biomaterials in diabetic wound healing. Over the past decade, researchers have explored the properties, mechanisms of action, and roles of various natural and synthetic biomaterials. These biomaterials include DNA nanomaterials, peptide hydrogels, cells, exosomes, and cytokines. These biomaterials play significant role in promoting angiogenesis, regulating inflammation, inhibiting bacteria, and enhancing cell proliferation and migration.
