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)@CuFeO (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 CuFeO 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 CuFeO nanoparticles incorporated into CS/PEO nanofibrous mats demonstrating its potential for successful application in wound treatment.
伤口愈合是一个复杂的过程,通常需要干预来加速组织再生并预防并发症。本研究的目的是通过评估其形态、机械性能和磁性能来评估生物活性壳聚糖@聚(氧化乙烯)@CuFeO(CS@PEO@CF)纳米纤维在伤口愈合应用中的潜力。此外,还进行了体外和体内研究,以研究其在促进伤口愈合治疗方面的效果。纳米粒子表现出显著的抗菌和抗氧化性能。在纳米纤维垫中,确定 CuFeO 的最佳浓度为 0.1%Wt/V。重要的是,该浓度不会对成纤维细胞的活力产生不利影响,这也确定了理想的浓度。支架的血液相容性显示出非溶血特性。此外,伤口愈合实验表明,成纤维细胞在伤口边缘的迁移和生长显著。这些纳米纤维垫被应用于治疗全层切除伤口的大鼠。对这些伤口的组织病理学分析表明,伤口愈合能力增强,皮肤内的皮脂腺和毛囊也得到了再生。总的来说,所开发的伤口敷料由 CS/PEO 纳米纤维垫中的 CuFeO 纳米粒子组成,表明其在伤口治疗中的成功应用具有潜力。
