Flexible materials, such as fabric, paper and plastic, with nanoscale particles that possess antimicrobial properties have a significant potential for the use in the healthcare sector and many other areas. The development of new antimicrobial coating formulations is an urgent topic, as such materials could reduce the risk of infection in hospitals and everyday life. To select the optimal composition, a comprehensive analysis that takes into account all the advantages and disadvantages in each specific case must be performed. In this study, we obtained an antimicrobial textile with a 100% suppression of E. coli on its surface. These CeO nanocoatings exhibit low toxicity, are easy to manufacture and have a high level of antimicrobial properties even at very low CeO concentrations. High-power ultrasonic treatment was used to coat the surface of cotton fabric with CeO nanoparticles.
诸如织物、纸张和塑料等具有抗菌特性纳米级颗粒的柔性材料，在医疗保健领域和许多其他领域有着巨大的应用潜力。开发新的抗菌涂料配方是一个紧迫的课题，因为这类材料可以降低医院和日常生活中的感染风险。为了选择最佳成分，必须进行全面分析，考虑每个具体案例中的所有优缺点。在本研究中，我们获得了一种表面对大肠杆菌抑制率达100%的抗菌纺织品。这些CeO纳米涂层毒性低、易于制造，即使在CeO浓度非常低时也具有高水平的抗菌性能。采用高功率超声处理将CeO纳米颗粒涂覆在棉织物表面。
