The MgO nanoparticles are widely used in many fields. However, the toxicity of these nanoparticles to cells and organs remains fairly undiscovered. In this study, the cytotoxicity of MgO nanoparticles on human umbilical vein endothelial cells (HUVECs) in vitro was examined. The morphology and size of MgO nanoparticles were analysed by the transmission electron microscope (TEM) and nanoparticle size...
When live endothelial cells imaged using atomic force microscopy (AFM), distortion of the cell shape could be caused by the interaction between the probe and cell membrane, which depends on the force and the scanning speed used. In this study, a shape recovering method was developed. Two forces were considered in the method: the vertical and the lateral force of the tip exerted on the cell membrane...
