摘要
测定了单壁碳纳米管(SWNTs)在生理盐水及LB培养基中对革兰氏阳性菌枯草芽孢杆菌(B.subtilis)的抑菌率,探讨了SWNTs的抑菌机理及培养基对SWNTs抑菌性的影响。用扫描电镜(SEM)、透射电镜(TEM)对有无LB(Luria-Bertani)培养基的SWNTs进行了表征。结果表明:SWNTs的抑菌性受环境影响,在生理盐水及LB培养基中,抑菌性能表现迥异。
We conducted a study to characterize the antimicrobial properties of SWNTs to B.subtilis in a saline solution or in a LB culture. Dimensions and the antibacterial ability of SWNTs in a saline solution were different from those in a LB culture. Transmission and scanning electron microscopes were used to characterize the SWNTs structure with and without LB culture. The antibacterial ability of SWNTs was affected by the environment of bacterial growth. The antibacterial mechanism of SWNTs was studied, too.
