摘要：

Here, multi-walled carbon nanotubes (CNT) were first functionalized with lysine under microwave irradiation. The water-dispersed CNT were obtained by diazonium-assisted functionalization. Formation of lysine on CNTs surface was confirmed by FUR, TGA, Raman and TEM techniques. Then, by minimal inhibitory concentration (MIC), antimicrobial activity of functionalized and pristine CNT was studied on three Gram-negative bacteria as well as three Gram-positive bacteria. The MIC results show that functionalized CNT with lysine were more effective than pristine CNT against all studied bacteria. This simple and efficient mechanism could be used to CNT functionalization with molecules containing primary amine groups. (C) 2011 Elsevier B.V. All rights reserved.
