The skin is one of the most essential organs of the body that plays a vital role. Protecting the skin from damage is a critical challenge. Therefore, the ideal wound dressing that has antibacterial, mechanical, biodegradable, and non-toxic properties can protect the skin against injury and accelerate and heal the wound.
In this study, a nano-wound dressing is designed for the first time. This work is aimed to optimize and act as a dressing to speed up the wound healing process.
Graphene Oxide (GO) was produced by the hummer method. In the next step, GO-copper (Cu) nanohybrid was prepared, then GO-Cu -Curcumin (Cur) nanohybrid was synthesized. Using the electrospinning method, polyvinyl alcohol (PVA)/GO-Cu -Cur were spun, and finally, related analyses were performed to investigate the properties and synthesized chemicals.
The results showed that the nanocomposite was synthesized correctly, and the diameter of the nanofibers was 328 nm. The use of PVA improved the mechanical properties. In addition, the wound dressing had biodegradable, antimicrobial, and non-toxic properties. The results of the scratch test and animal model showed that this nanocomposite accelerated wound healing and after 14 days showed 92.25% wound healing.
The synthesized nanocomposite has the individual properties and characteristics of an ideal wound dressing and replaces traditional methods for wound healing.
皮肤是人体最重要的器官之一,起着至关重要的作用。保护皮肤免受损伤是一个关键的挑战。因此,理想的伤口敷料应具有抗菌、机械、可生物降解和无毒的特性,可以保护皮肤免受伤害,并加速和治愈伤口。
本研究首次设计了一种纳米伤口敷料,旨在优化并用作敷料,以加速伤口愈合过程。
采用锤击法制备氧化石墨烯(GO)。下一步,制备 GO-铜(Cu)纳米杂化物,然后合成 GO-Cu-姜黄素(Cur)纳米杂化物。采用静电纺丝法纺制聚偏二氟乙烯(PVA)/GO-Cu-Cur,最后对相关性能和合成化学品进行分析。
结果表明,纳米复合材料的合成正确,纳米纤维的直径为 328nm。PVA 的使用提高了机械性能。此外,伤口敷料具有可生物降解、抗菌和无毒的特性。划痕试验和动物模型的结果表明,这种纳米复合材料能加速伤口愈合,在 14 天后,伤口愈合率达到 92.25%。
合成的纳米复合材料具有理想伤口敷料的个体特性和特征,可替代传统的伤口愈合方法。
