Figure 3From: 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 Growth curve of HUVECs exposed to different concentrations of 30 and 50 nm GMNPs (A) and the doubling time of these HUVECs (B). HUVEC proliferation was affected by the GMNPs in a size-, concentration- and time-dependent manner.Back to article page
