摘要
断然控告的单个围的碳 nanotubes (SWNTs+) 被与 CONHC6H12NH3+ 结合准备。双海滨 DNA (dsDNA ) 链经由静电的相互作用被装载到 SWNTs+ 上。SWNTs+ 表演改善了与为充电的自由单身者的相比向 dsDNA 装载效率(353.5 μ g /mg ) 围的碳 nanotubes (SWNT )(82.9 μ g /mg ) 。
The positively charged single walled carbon nanotubes (SWNTs^+) were prepared by conjugating with -CONH-C6H12-NH3^+. The double strand DNA (dsDNA) chains were loaded onto SWNTs^+ via the electrostatic interactions. SWNTs^+ shows improved loading efficiency (353.5 μg/mg) toward dsDNA compared with that of charged free single walled carbon nanotubes (SWNTs) (82.9 μg/mg).
