MXenes in the application of diabetic foot: mechanisms, therapeutic implications and future perspectives

Diabetic foot represents a significant healthcare challenge, accounting for a substantial portion of diabetes-related hospitalizations and amputations globally. The complexity of diabetic foot management stems from the interplay of poor glycemic control, neuropathy, and peripheral vascular disease, which hinder wound healing processes. The high incidence, recurrence, and amputation rates associated with diabetic foot underscore the urgency for innovative treatment strategies. Recent advancements in nanotechnology, particularly the emergence of MXenes (two-dimensional transition metal carbides and/or nitrides), have shown promising potential in addressing these challenges by offering unique physicochemical and biological properties suitable for various biomedical applications. It is a novel potential strategy for diabetic foot wound healing in the future. This review comprehensively summarizes current knowledge, unique characteristics, and underlying mechanisms of MXenes in the context of diabetic foot management. Additionally, we propose the potential application of MXenes-based therapeutic strategies in diabetes foot. Furthermore, we also provide an overview of their current challenges and the future perspectives in related fields of diabetic wound healing.
