SAEC Production of ROS by CoO and La2O3 nanoparticles. SAEC were treated for 6 or 24 h with CoO or La2O3 nanoparticles with the following doses: 0.0, 5.0, 25.0, and 50.0 μg/ml and for the last 30 min 5 μM DCFDA was added to analyze superoxide production. Fluorescence was measured using a plate reader. Values were normalized to 0.0 μg/ml control ± Standard error. n = 3, * indicates P < .05 compared to 0.0 μg/ml control. + indicates P < .05 compared to La2O3 nanoparticles.
