In the current study, a sustainable approach was adopted for the green synthesis of silver nanoparticles, green synthesis of copper nanoparticles, and the investigation of the phytochemical and biological screening of bark, leaves, and fruits of Ehretia acuminata (belongs to the family Boraginaceae). Subsequently, the prepared nanoparticles and extracted phytochemicals were loaded on cotton fibres. Surface morphology, size, and the presence of antimicrobial agents (phytochemicals and particles) were analysed by scanning electron microscopy, dynamic light scattering, and energy-dispersive X-ray spectroscopy. The functional groups and the presence of particles (copper and silver) were found by FTIR and XRD analyses. The coated cotton fibres were further investigated for antibacterial (qualitative and quantitative), antiviral, and antifungal analysis. The study revealed that the herb-encapsulated nanoparticles can be used in numerous applications in the field of medical textiles. Furthermore, the utility of hygienic and pathogenic developed cotton bandages was analysed for the comfort properties regarding air permeability and water vapour permeability. Finally, the durability of the coating was confirmed by measuring the antibacterial properties after severe washing.
在当前研究中,采用了一种可持续的方法用于银纳米颗粒的绿色合成、铜纳米颗粒的绿色合成,以及对尖叶厚壳树(紫草科)树皮、树叶和果实进行植物化学和生物学筛选研究。随后,将制备的纳米颗粒和提取的植物化学物质负载到棉纤维上。通过扫描电子显微镜、动态光散射和能量色散X射线光谱分析表面形态、尺寸以及抗菌剂(植物化学物质和颗粒)的存在情况。通过傅里叶变换红外光谱(FTIR)和X射线衍射(XRD)分析确定官能团以及颗粒(铜和银)的存在情况。对包覆的棉纤维进一步进行抗菌(定性和定量)、抗病毒和抗真菌分析。研究表明,草本植物封装的纳米颗粒可用于医用纺织品领域的众多应用。此外,针对透气性和水蒸气透过性等舒适性能,分析了卫生型和致病型棉绷带的实用性。最后,通过测量剧烈洗涤后的抗菌性能来确认涂层的耐久性。
