Figure 8From: Superparamagnetic core/shell GoldMag nanoparticles: size-, concentration- and time-dependent cellular nanotoxicity on human umbilical vein endothelial cells and the suitable conditions for magnetic resonance imaging ROS generation in HUVECs. (A) and (C) for HUVECs labeled with 30 nm GMNPs; (B) and (D) for HUVECs labeled with 50 nm GMNPs. * P < 0.05, compared with the control group. ROS induction depended on size, concentration and time. A significant elevation in the ROS was detected with increasing size, concentration and time.Back to article page
