Treatment of burn injury is clinically challenging one, therefore several steps and noteworthy approaches have been taken to improve wound mechanisms. Citrus pectin plays a stabilizing agent to synthesis of ZnO nanoparticles (ZnO NPs). The present study is focused on ZnO loaded collagen/chitosan nanofibrous were synthesized by electrospinning method using ZnO NPs. The chemical structure, phase purity and morphological observation were investigated under spectroscopic and mircoscopic techniques and demonstrated their suitable properties as a wound healing material. In addition, that prepared nanoparticles loaded biopolymeric fibrous nanomaterial showed suitable antibacterial activity against S. aureus and E. coli bacterial pathogens and also in vitro studies was confirmed the enhanced proliferation, cell viability and biocompatibility. In vitro evaluations have been exhibited acceptable cell proliferation is observed throughout the ZnO loaded Coll/CS nanofibrous within 3 days, which was comparable to the control material. In vivo wound healing ability was monitored on the rat wound experimental model. From the in vivo observations, revealed that the loaded of ZnO NPs with Coll/CS nanofibrous can effectively quicken wound healing mechanism, expressed in the initial stage healing process. These results suggest that ZnO loaded collagen/chitosan nanofibrous is a potential candidate for wound healing applications with enhanced biological properties.
烧伤的治疗在临床上具有挑战性,因此已经采取了几个步骤和值得注意的方法来改善伤口机制。柑橘果胶在合成氧化锌纳米粒子(ZnO NPs)中起到稳定剂的作用。本研究专注于通过电纺丝方法合成负载 ZnO 的胶原/壳聚糖纳米纤维,使用 ZnO NPs。通过光谱和显微镜技术研究了化学结构、相纯度和形态观察,并证明了它们作为伤口愈合材料的合适特性。此外,制备的负载纳米颗粒的生物聚合物纤维纳米材料显示出对金黄色葡萄球菌和大肠杆菌等细菌病原体的合适抗菌活性,并且体外研究证实了增强的增殖、细胞活力和生物相容性。体外评估表明,在 3 天内观察到负载 ZnO 的 Coll/CS 纳米纤维具有可接受的细胞增殖,与对照材料相当。在大鼠伤口实验模型上监测体内伤口愈合能力。从体内观察结果表明,负载 ZnO NPs 的 Coll/CS 纳米纤维可以有效地加速伤口愈合机制,在初始愈合过程中得到体现。这些结果表明,负载 ZnO 的胶原/壳聚糖纳米纤维是一种具有增强生物学特性的潜在伤口愈合应用候选材料。
