From: Synergistic antibacterial effect of copper and silver nanoparticles and their mechanism of action
Luminescence of biosensor bacteria as reaction to components. Luminescence (LC) of Escherichia coli MC1061 pSLcueR/PDNPcopAlux as a reaction to 4 h incubation with components alone (a). The significant shift of peak LC to the left in the mix of copper components with cAg compared to cAg alone (b). No shift of peak LC in the mixture of copper components with AgNO3 compared to AgNO3 alone (c). Representative Figures are from 3 independent experiments. cAg, Coated silver nanoparticles; AgNO3, Silver nitrate; CuO, Copper oxide; CuO–NH2, Copper oxide coated with amino groups; CuO–COOH, Copper oxide coated with carboxy groups; CuSO4, Copper sulphate.
