Wound healing is a normal biological process which is achieved through four indeed and highly involuntary phases: hemostasis, inflammation, proliferation and remodeling. All four phases must be happened in the appropriate sequence and time frame work to heal a wound successfully. Nanotechnology has appeared as a major platform to treat acute and chronic wounds. Various nanotechnology based drug delivery systems represents multiple functions and unique possessions associated with mechanism of wound healing. Gold, silver and copper nanoparticles and zinc oxide nanoparticles have shown impending therapeutic effects on wound healing. Nanoparticles such as nanocapsules, solid lipid nanoparticles and polymeric nanocomplexes are ideal vehicles to improve the effect of drugs (antibiotics, growth factors, etc.) in wound healing due to their specific characteristics. In this review, discussed on the significant findings in the area of nanoparticles in wound treatments.
