Abstract The aim of this study is to prepare nonwoven fabrics carrying silver nanoparticles (AgNPs), and to investigate their antibacterial activities and cytotoxicities in parallel. AgNPs were impregnated from their nanoemulsions onto two commercially available nonwoven fabrics: pure-cotton fabrics (PCF) and polyester/viscous fabrics (PVF), by a simple adsorption (dipping) and were then heat stabilized. PCF exhibited stronger antibacterial effects on both Staphylococcus aureus and Escherichia coli. In-vitro cell culture studies demonstrated that AgNPs nanoemulsions and also fabrics carrying them were cytotoxic on L929-fibroblasts in all concentrations used here (6.25-400 ppm) in different extends. Only the fabrics loaded with AgNPs using nanoemulsion with the lowest concentration of 6.25 ppm exhibited low cytotoxicity but were still antibacterial.
摘要 本研究旨在制备负载银纳米颗粒(AgNPs)的无纺布,并同时研究其抗菌活性和细胞毒性。通过简单的吸附(浸渍)方法,将AgNPs从其纳米乳液中负载到两种市售无纺布上:纯棉织物(PCF)和聚酯/粘胶织物(PVF),然后进行热稳定处理。PCF对金黄色葡萄球菌和大肠杆菌均表现出更强的抗菌效果。体外细胞培养研究表明,AgNPs纳米乳液以及负载它们的织物在此处使用的所有浓度(6.25 - 400 ppm)下,对L929成纤维细胞均有不同程度的细胞毒性。只有使用最低浓度6.25 ppm纳米乳液负载AgNPs的织物表现出低细胞毒性,但仍具有抗菌性。
