Antimicrobial Hydrogel for Diabetic Wound Treatment
Summary: This review summarizes recent advances in antimicrobial hydrogels designed for diabetic wound treatment. Hydrogels maintain a moist healing environment, offer controlled release of antimicrobials (silver, antibiotics, natural agents), and provide mechanical support while reducing bioburden and biofilm formation. Various formulations (chitosan, alginate, PEG, hyaluronic acid-based) demonstrate antibacterial activity against common DFU pathogens, modulation of inflammation, and promotion of angiogenesis/collagen deposition. Preclinical and early clinical data show accelerated wound closure, reduced infection rates, and improved healing in diabetic models. Highlights advantages over traditional dressings: better conformability, sustained action, and multifunctionality. Discusses challenges (scalability, regulatory approval) and future directions for smart/smart-responsive antimicrobial hydrogels in chronic diabetic foot ulcer management.
Key Highlights:
- Moist environment + controlled antimicrobial release
- Effective against DFU pathogens and biofilm
- Promotes angiogenesis and tissue repair
- Relevance: Multifunctional platform for hard-to-heal diabetic wounds
