The endeavor was to adopt a facile bi-layered approach to fabricate a novel PVA-chitosan-collagen-licorice nanofibrous mat (PCCLNM) with maintaining the spinning parameters and conditions to assess the synergistic antibacterial action of two biopolymers and having properties for repairing tissues. Bonding behavior, morphological orientation, antibacterial activity, and moisture management features of the electrospun nanofibrous mat were investigated using various characterization techniques. The FTIR analysis of the manufactured nanofibrous mat revealed characteristic peaks of licorice, chitosan, collagen, and PVA polymer, confirming the presence of all polymers in the sample. Additionally, a scanning electron microscopy (SEM) image attributes the development of nanofibers with an average diameter for top and bottom sides were 219 and 188 nm respectively. Furthermore, moisture management tests (MMT) confirm PCCLNM's slow absorption and drying capabilities. Apart from that, a disk diffusion method was used to investigate antibacterial activity against the bacteria , which revealed a strong presence of antibacterial activity with a 20 mm zone of inhibition due to the chemical constituents of licorice and chitosan compound. The developed bio-nanocomposite could have a potential application as wound healing material.
本研究采用简便的双层方法制备了一种新型的 PVA-壳聚糖-胶原-甘草纳米纤维垫(PCCLNM),同时保持纺丝参数和条件不变,以评估两种生物聚合物的协同抗菌作用,并具有修复组织的特性。利用各种表征技术研究了电纺纳米纤维垫的结合行为、形态取向、抗菌活性和保湿性能。制造的纳米纤维垫的傅里叶变换红外(FTIR)分析显示出甘草、壳聚糖、胶原和 PVA 聚合物的特征峰,证实了样品中存在所有聚合物。此外,扫描电子显微镜(SEM)图像显示,顶部和底部的纳米纤维平均直径分别为 219nm 和 188nm。此外,保湿性能测试(MMT)证实了 PCCLNM 的缓慢吸收和干燥能力。除此之外,还使用圆盘扩散法研究了对细菌的抗菌活性,结果表明由于甘草和壳聚糖化合物的化学成分,抗菌活性很强,抑菌圈达到 20mm。开发的生物纳米复合材料可能具有作为伤口愈合材料的应用潜力。
