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

Figure 15

Antibacterial activity of ZnO/Ag nanocomposite against S. aureus. The paper disks were impregnated with the following suspension of copper oxide nanoparticles: A = 5 mg/ml, B = 2 mg/ml, C = 1 mg/ml, D = 0.5 mg/ml. E = 0.25 mg/ml, F = 0.1 mg/ml, and G = 0 mg/ml.
