A Comparative Study of Antibacterial Activity of CuO/Ag and ZnO/Ag Nanocomposites

Table 3

The results of microdilution test presenting the relative percentages (%) of bacteria cell death by respective nanoparticles after 24 hours of antibacterial kinetic study. “EC” represents Escherichia coli, while “SA” represents Staphylococcus aureus.
