Composite thin films containing multi-walled carbon nanotube (MWCNT) and electro-deposited silver nanoparticles (Ag NPs) with varied size and density were prepared. The antimicrobial properties of the thin films were evaluated against two Staphylococcus aureus strains. Bacterial suspensions were put in contact with the MWCNT/Ag NP films and NBT assay was used to determine the antibacterial effectiveness of the surfaces following incubation. A significant reduction in the number of viable cells of both microorganisms was observed compared to bare glass and MWCNT surface. The results also showed that the density of Ag NPs had an effect on the antibacterial activity of MWCNT/Ag NP films.
