Silver nanoparticle-modified multiwalled carbon nanotubes (MWCNTs) nanocomposites (AgCNTs) were synthesized by photochemical reduction method, their antimicrobial effect on both Gram negative and Gram positive bacteria, using E. coli and Bacillus anthracis as model bacteria, respectively, were investigated. The results indicated that AgCNTs exhibited more potent antibacterial effects against both Gram negative and Gram positive bacterium compared to Ag nanoparticles (Ag NPs). The minimal inhibitory concentrations (MICs) of AgCNTs against E. coli cells (0.5 μg/mL) and B. anthracis cells (0.8 μg/mL) was 1/20 times and 1/17.5 of the MICs of Ag NPs against E. coli and B. anthracis, respectively. Further study on the antibacterial effect of combination treatment of AgCNTs with oxidizing antimicrobial.. View More»
