Time dependent induction of ROS by SWCNT (6 μg/ml) in BJ Foreskin cells. Cells were incubated in CO₂ incubator and treated as described in Figure 1. Fluorescence was measured after each time interval and the values were normalized with the protein content in each well. Values are mean±SD of 8 wells and is a representative from three experiments performed independently. (◇) DMF; (▲) SWCNT(■); H₂O₂.
