| 摘 要： | 利用病毒滴度测定和MDCK细胞电镜观察法,初步探讨了在365nm的黑光灯(UV)照射下,纳米Cu2+/TiO2抗菌膜对禽流感病毒(H9N2)的光催化灭活效应,并分别考察了UV强度、UV照射时间以及H9N2病毒量对H9N2病毒光催化灭活效应的影响.实验结果表明,在365nm黑光灯的照射下,纳米Cu2+/TiO2抗茵膜对H9N2病毒具有显著的灭活效应,在UV强度为0.5mW/cm2、UV照射时间为2.5h、病毒量为0.1ml时,H9N2病毒的灭活率达到了100%.研究结果表明,纳米Cu2+/TiO2抗菌膜在抑制禽流感(H9N2)病毒在环境媒介中的扩散与传播方面有潜在的应用价值.

| Abstract: | Nano-Cu2+/TiO2 was synthesized through a sol-gel method,and its photocatalysis of inactivation efficiency on avian influenza(H9N2) were evaluated under 365nm UV black light.Hemagglutination tests were used to determine the change of the titer of H9N2.Microscope was used to observe the deformation of MDCK cells.The inactivation efficiencies of nano-Cu2+/TiO2 sol on H9N2 virus were studied by adjusting the UV intensity,the UV illumination time,and the quantity of H9N2.The results show that nano-Cu2+/TiO2 has ... |
