Metallic nanoparticles such as zinc oxide (ZnONPs), copper oxide (CuONPs), and silver (AgNPs) were synthesized in gram scale using green methods. The antibacterial cotton fibers/nanoparticles (cotton fibers/NPs) composite pads were prepared, and nanoparticle binding/release tests were performed. All the NPs were crystalline and showed characteristic XRD diffraction peaks and showed the characteristic FTIR bands of the respective nanoparticles. All the NPs showed strong antimicrobial activity against Gram-positive and Gram-negative pathogenic bacteria. The NPs were attached to the cotton pad by adsorption at different extent depending on the types of nanoparticles. The adsorption and release of nanoparticles on and from cotton pads were also dependent on the types of nanoparticles. The NPs-adsorbed cotton pads showed potent antibacterial activity against pathogenic bacteria such as Escherichia coli, Listeria monocytogenes, Staphylococcus aureus, and Staphylococcus epidermis. The developed NPs-adsorbed cotton pads have potential to be used as wound dressings and antibacterial food packaging applications.
采用绿色方法在克级规模上合成了氧化锌 (ZnONPs)、氧化铜 (CuONPs) 和银 (AgNPs) 等金属纳米粒子。制备了抗菌棉纤维/纳米粒子（棉纤维/NPs）复合垫，并进行了纳米粒子结合/释放测试。所有的 NPs 都是结晶的，显示出特征的 XRD 衍射峰和各自纳米粒子的特征 FTIR 带。所有的 NPs 对革兰氏阳性和革兰氏阴性病原菌都表现出很强的抗菌活性。纳米粒子通过吸附不同程度地附着在棉垫上，这取决于纳米粒子的类型。纳米粒子在棉垫上的吸附和释放也取决于纳米粒子的类型。吸附了纳米粒子的棉垫对大肠杆菌、单核细胞增生李斯特菌、金黄色葡萄球菌和表皮葡萄球菌等病原菌表现出很强的抗菌活性。开发的吸附纳米粒子的棉垫具有用作伤口敷料和抗菌食品包装应用的潜力。
