Abstract

In the current study, cupric oxide nanoparticles (CuO NPs) are chemically synthesized and blended with polyvinyl alcohol and chitosan (PVA-CS) solution to produce nanofibrous wound dressing material using an electrospinning technique. The fibrous morphology of CuO-blended nanofibers was studied by SEM, showing smooth beads and uniform nanofibers with an average diameter of around 86.4 nm. The nanofibers are further characterized using XRD to confirm the presence of CuO NPs. The incorporation of CuO NPs with polymer is evident from the peaks obtained from infrared spectrum. The addition of CuO NPs retained the hydrophilic nature of scaffold, as evident from the contact angle measurement. Further, the wound healing properties of scaffold are apparent from the studies such as antioxidant activity, MTT assay, wound scratch assay, and antibacterial studies. These results indicate the greater efficacy of CuO NPs incorporated in PVA/CS for wound healing applications.

用于伤口愈合的浸渍有 CuO 纳米粒子的电纺 PVA/ 壳聚糖纳米纤维支架的合成
在本研究中,采用电纺丝技术化学合成了氧化铜纳米粒子(CuO NPs),并将其与聚乙烯醇和壳聚糖(PVA-CS)溶液混合制成纳米纤维伤口敷料。通过扫描电子显微镜研究了 CuO 混合纳米纤维的纤维形态,结果显示纳米纤维呈光滑珠状,均匀一致,平均直径约为 86.4 nm。使用 XRD 对纳米纤维进行了进一步表征,以确认 CuO NPs 的存在。从红外光谱得到的峰值可以明显看出 CuO NPs 与聚合物的结合。从接触角测量结果可以看出,CuO NPs 的加入保持了支架的亲水性。此外,从抗氧化活性、MTT 试验、伤口划痕试验和抗菌研究等研究中也可以明显看出支架的伤口愈合特性。这些结果表明,PVA/CS 中的 CuO NPs 在伤口愈合应用中具有更高的功效。

期刊介绍: Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
