Intracellular ROS production in HepG2 cells and L02 cells after gold nanoparticles (AuNPs) exposure was detected by confocal fluorescence microscopy. Cells were treated with different sized AuNPs at the concentration of 12.50 µg/mL for 4 hrs, respectively. Intracellular ROS was measured using 10 µM DCF-DA probe.
