MIC of Cu₂O NPs against P. aeruginosa CB1 and B. subtilis CN2 at different pHs evaluated by measuring optical density at 600 nm (OD₆₀₀) after incubation at 37 °C, 180 rpm for 24 h. Data are presented as mean ± SD of three independent experiments, each performed in triplicates. Variation between sample means are analysed by ANOVA.
