| description | Different microorganisms are present in nature, some of which are assumed to be hazardous to the human body. It is crucial to control their continuing growth to improve human life. Nanomaterial surface functionalization represents a current topic in continuous evolution that supports the development of new materials with multiple applications in biology, medicine, and the environment. This study focused on the antibacterial activity of different nanocomposites based on functionalized multi-walled carbon nanotubes against four common bacterial strains. Two metal oxides (CuO and NiO) and two antibiotics (azithromycin and ciprofloxacin) were selected for the present study to obtain the following nanocomposites: MWCNT-COOH/Antibiotic, MWCNT-COOH/Fe<sub>3</sub>O<sub>4</sub>/Antibiotic, and MWCNT-COOH/Fe<sub>3</sub>O<sub>4</sub>/MO/Antibiotic. The present study included two Gram-positive bacteria (<i>Staphylococcus aureus</i> and <i>Enterococcus faecalis</i>) and two Gram-negative bacteria (<i>Escherichia coli</i> and <i>Pseudomonas aeruginosa</i>). Ciprofloxacin (Cip) functionalized materials (MWCNT-COOH/Fe<sub>3</sub>O<sub>4</sub>/Cip) were most efficient against all tested bacterial strains; therefore, we conclude that Cu and Ni reduce the effects of Cip. The obtained results indicate that the nanocomposites functionalized with Cip are more effective against selected bacteria strains compared to azithromycin (Azi) functionalized nanocomposites. The current work determined the antibacterial activities of different nanocomposites and gave fresh insights into their manufacture for future research regarding environmental depollution. |
