Abstract:

Bacteria are becoming resistant to the antibiotics prescribed and therefore new treatments are essential to be developed. Multiwall carbon  nanotubes (MWNTs) have interesting antibacterial activities and offering a promising new treatment preventing bacteria from becoming resistant. With this aim, we report for the first time three novel modified carboxylated multiwall carbon nanotubes consisting of  MWNT-Dapsone, MWNT-Dapsone-imine and MWNT-Dapsone-imine. Copper complex.  The functionalized carboxylated multiwall nanotubes were then characterized by FT-IR, Raman, TEM. Moreover, the antibacterial activity of the MWNT-COOH (A), MWNT-dapsone (B), MWNT-Dapsone-imine (C) MWNT-Dapsoneimine.Copper complex (D) ,  Dapsone (E(, Dapsone-imine (F),    has been investigated against  gram-negative Escherichia coli and gram-positive Staphylococcus aureus. These results show that compund F exhibited significant antibacterial activity and have a potential to be used as antibacterial agent.
