Titanium oxide (TiO(2)) nanoparticles (NPs) in their two forms, anatase and rutile, were synthesized and deposited onto the surface of cotton fabrics by using ultrasonic irradiation. The structure and morphology of the nanoparticles were analyzed by using characterization methods such as XRD, TEM, STEM, and EDS. The antimicrobial activities of the TiO(2)-cotton composites were tested against Escherichia coli (gram-negative) and Staphylococcus aureus (gram-positive) strains, as well as against Candida albicans. Significant antimicrobial effect was observed, mainly against Staphylococcus aureus. In addition, the combination of visible light and TiO(2) NPs showed enhanced antimicrobial activity.
锐钛矿型和金红石型二氧化钛(TiO2)纳米粒子(NPs)通过超声辐射被合成并沉积到棉织物表面。采用 XRD、TEM、STEM 和 EDS 等表征方法对纳米粒子的结构和形态进行了分析。测试了 TiO2-棉复合材料对大肠杆菌(革兰氏阴性)和金黄色葡萄球菌(革兰氏阳性)以及白色念珠菌的抗菌活性。观察到显著的抗菌效果,主要针对金黄色葡萄球菌。此外,可见光和 TiO2 NPs 的组合显示出增强的抗菌活性。
