Abstract

Delayed wound healing is one of the main complications facing diabetic patients worldwide. It can be followed by serious consequences such as ulcer, gangrene, amputation unless treated correctly. Four phases of normal wound healing are compromised in diabetic patients due to complex pathophysiology; thus, wounds healing time is prolonged. Consequently, the probability of wounds infections in diabetic patients is higher than non-diabetic patient and it is much higher with immunocompromised diabetic patients. There are several strategies for treatment of diabetic wounds such as; dressings, growth factors, stem cells, antidiabetic drugs, antihypertensive drug, etc. However, some of these strategies are still under investigations to ascertain their safety, while others are clinically non-applicable due to rapid biodegradation. Nanotechnology might be a novel and a promising alternative strategy for diabetic wound healing as nanoparticles could overcome limitations of medical products currently used. Some nanoparticles such as; metal-based nanoparticles (MBNPs) demonstrated an excellent antibacterial activity including resistant strains inhabitant diabetic wound, moreover, some of MBNPs could enhance the healing of wound in diabetic patients via modulating many disturbed issues recorded in four phases of wound healing. This review explores the recent literature in this area, discusses the complications associated diabetic patients with special focus on delayed wound healing, pathophysiology of wound healing in diabetic patients, treatment approved for wound healing and controlling wound infection. In addition, shedding the light on nanotechnology application to improve wound healing, with a special concern devoted to MBNPs including their antibacterial mechanisms and barriers faced to their clinical application.
