Figure 7From: The oxidative potential of differently charged silver and gold nanoparticles on three human lung epithelial cell types Effect of FCS on the ROS production of chitosan-coated Au NPs (Au-CHIT-H) in a cell-free system. A. Incubated in RPMI w/o FCS. B. Incubated in PBS + FCS. Fluorescence was measured at 530 nm (excitation 485 nm) every 10 minutes after an initial incubation period of 15 minutes. Means ± SEM of n=3 are shown.Back to article page
