The sidewall modified single-walled carbon nanotubes (SWNTs) with amino-containing substituents were prepared using the radicals generated by the photolysis of acetonitrile. A subsequent treatment of modified SWNTs with the Ag colloid gave an attachment of Ag nanoparticles on the surface of SWNTs through the functionalized linkages. The Ag nanoparticle-modified SWNTs evaluated by antibacterial tests showed strong activities against Escherichia coli and Staphylococcus aureus. However, the use of Ag nanoparticle-modified SWNTs on simulated body fluid exhibited weaker antibacterial activity.
利用乙腈光解产生的自由基制备了带有含氨基取代基的侧壁修饰单壁碳纳米管（SWNTs）。随后用银胶体对修饰后的SWNTs进行处理，通过功能化连接使银纳米颗粒附着在SWNTs表面。经抗菌测试评估，银纳米颗粒修饰的SWNTs对大肠杆菌和金黄色葡萄球菌表现出很强的活性。然而，在模拟体液中使用银纳米颗粒修饰的SWNTs时，其抗菌活性较弱。
