Nanomedicine In Healing Chronic Wound

Chronic wounds, such as diabetic foot ulcers, pressure sores, and venous leg ulcers, represent a significant global healthcare burden due to their prolonged healing times, high risk of infection, and resistance to conventional therapies. Nanomedicine offers a promising frontier in wound management by enabling targeted drug delivery, antimicrobial action, and enhanced tissue regeneration at the nanoscale. This review explores recent advances in the application of nanotechnology for chronic wound healing, including the development of nanoparticle-based dressings, nanocarriers for controlled release of bioactive agents, and nanosystems that mimic the extracellular matrix to support cellular proliferation and angiogenesis. We highlight the mechanisms by which nanomaterials—such as silver, gold, silica, and polymeric nanoparticles—promote wound repair, reduce inflammation, and combat multidrug-resistant pathogens. Furthermore, the review discusses current challenges in clinical translation, including biocompatibility, scalability, and regulatory hurdles, while outlining future perspectives on integrating nanomedicine with smart biosensors and personalized wound care strategies. Overall, nanotechnology holds transformative potential to overcome the limitations of traditional wound therapies and accelerate healing in chronic, non-healing wounds.
