Advances in biomaterials and regenerative medicine for diabetic foot ulcer therapy

Abstract

Diabetic foot ulcer (DFU), a severe complication of diabetes mellitus, presents significant clinical challenges due to its rapid deterioration and high morbidity rates. While conventional therapies exist kinds of limitations, their clinical utility is frequently constrained. Recent advancements in biomedical engineering have introduced innovative therapeutic modalities, particularly nanomaterials and hydrogels. However, emerging technologies face translational barriers including immature manufacturing processes leading to elevated costs, and insufficient long-term safety data due to limited clinical validation periods. Current clinical studies remain constrained by small cohort sizes and preliminary-stage investigations. The purpose of this study was to review traditional primary treatment and simultaneously combine clinical data to increase the speed of innovative safety, cost, and effectiveness indicator testing.
