Toxicity screening. a MTT assay performed in HepG2 cells after 24 h of exposure with AgNPs (0–10 µg/mL) or CDDP (0–200 µM). b MTT assay performed in HepG2 cells after 24 h of exposure with AgNPs (1–5 µg/mL), CDDP (10 or 40 µM) and corresponding combinations. Mean + standard deviation (SD) of three independent experiments in triplicate. Asterisks indicate difference in comparison to the control (***p < 0.001); sharp symbol (#) indicates toxicological interaction
