ROS-Mediated Apoptosis and Genotoxicity Induced by Palladium Nanoparticles in Human Skin Malignant Melanoma Cells

Figure 4

ROS production induced by PdNPs. (a) The fluorescence image of A375 cells treated with 20–40 μg/ml of PdNPs for 24–48 h and stained with DCFHDA. Bar = 400 μm. (b) % ROS production due to PdNPs in cells. Images were snapped in phase contrast cum fluorescence microscope (Nikon, model 80i). Each value represents the mean ± SE of three experiments. and versus control.
