Oxidative stress cytotoxicity induced by platinum-doped magnesia nanoparticles in cancer cells by Mohamed Qasim, Al-Fahdawi

“…Pt/MgO nanoparticles were cuboid and in the nanosize range of 30–50 nm. The cytotoxicity of Pt/MgO nanoparticles was determined via the 3-(4,5-dimethylthiazol-2-yl)−2,5-diphenyltetrazolium bromide assay on the human lung and colonic cancer cells (A549 and HT29 respectively) and normal human lung and colonic fibroblasts cells (MRC-5 and CCD-18Co repectively). …”
