Diabetic Foot Ulcers, Diabetes Mellitus, Silver Nanoparticles, Nanomedicine, Chronic Ulcers.


Diabetic foot ulcers are highly susceptible to microbial infections and are the leading cause of lower limb hospitalization and amputation in diabetic patients. Due to their antimicrobial and anti-inflammatory properties, silver nanoparticles (AgNPs) are the most widely used nanomaterial in biomedicine. Herein, we present the usage of AgNPs for the treatment of diabetic foot ulcers with a stage II in Wagner classification. In addition to conventional antibiotic treatment, the ulcers were treated with topical administration of AgNPs at a concentration of 1.2 mg/ml of metallic silver. The results showed a significant improvement in the evolution of the ulcers, where the edges of the lesion were effectively approached, granulation tissue being observed, edema decreased and fibrin plaques. These results form the basis for further studies on the use of AgNPs for the treatment of chronic ulcers of different origins.
