Fig. 4From: Elucidating the cellular response of silver nanoparticles as a potential combinatorial agent for cisplatin chemotherapyIntracellular concentrations of Ag and Pt in a HepG2 cells and b THLE2 cells exposed for 4 h. Results are expressed in ppm/103 cells. Mean + SD of three independent experiments. Asterisks indicate difference in comparison to the correspondent metal uptake for single exposures (*p < 0.05); sharp symbol (#) indicates toxicological interactionBack to article page
