Fig. 7. Catalase activity in the WRL-68 cell lines on exposure to the CuO NPs. The catalase activity was measured using cell lysates of the cells. The WRL-68 cells were exposed to concentrations of 250 μM, 500 μM, 750 μM, and 1000 μM of CuO NPs for 24 h. The experiments were performed in triplicate and the data were expressed as the mean of three independent experiments.
