Bioactive chitosan/poly(ethyleneoxide)/CuFe2O4 nanofibers for potential wound healing.

ABSTRACT

Wound healing is a complex process that often requires intervention to accelerate tissue regeneration and prevent complications. The goal of this research was to assess the potential of bioactive chitosan@poly (ethylene oxide)@CuFe2O4 (CS@PEO@CF) nanofibers for wound healing applications by evaluating their morphology, mechanical properties, and magnetic behavior. Additionally, in vitro and in vivo studies were conducted to investigate their effectiveness in promoting wound healing treatment. The nanoparticles exhibited remarkable antibacterial and antioxidant properties. In the nanofibrous mats, the optimal concentration of CuFe2O4 was determined to be 0.1% Wt/V. Importantly, this concentration did not adversely affect the viability of fibroblast cells, which also identified the ideal concentration. The scaffold's hemocompatibility revealed nonhemolytic properties. Additionally, a wound-healing experiment demonstrated significant migration and growth of fibroblast cells at the edge of the wound. These nanofibrous mats are applied to treat rats with full-thickness excisional wounds. Histopathological analysis of these wounds showed enhanced wound healing ability, as well as regeneration of sebaceous glands and hair follicles within the skin. Overall, the developed wound dressing comprises CuFe2O4 nanoparticles incorporated into CS/PEO nanofibrous mats demonstrating its potential for successful application in wound treatment.
