Background: Chronic ulcers represent a significant challenge for patients with compromised microcirculation. As a novel branch of research, catalytic nanomedicine has exhibited promising outcomes with the development of nanostructured composites designed to disinfect and improve the healing of chronic wounds through the incorporation of bionanocatalysts within gel matrices.
Purpose: This study aimed to assess the impact of bionanocatalysts on 4 patients suffering from chronic venous ulcers, which had previously been indicated for lower extremity amputation.
Methods: Bionanocatalysts were synthesized and incorporated into a gel matrix. Monthly debridement was conducted with the objective of completely removing nonviable tissue. The bionanocatalyst-embedded gel was applied every other day, covering the entire wound surface and secured with a secondary dressing.
Results: Encouragingly, all cases exhibited complete wound closure, and patients reported no adverse side effects.
Conclusion: These findings offer robust support for the utilization of this technology in wound healing and prompt a reevaluation of the hypothesis regarding the mechanism of action of bionanocatalysts in chronic wounds. Future research endeavors should aim to quantitatively assess the bionanocatalysts' influence on the trajectory of wound healing, as well as address the myriad challenges associated with managing chronic wounds.
