Fig. 3. Effect of co-treatment with IONPs and fatty acids on Alexander and HepG2 cell viability. Alexander (a) or HepG2 (b) cells were co-treated with indicated concentrations of IONPs and either OA or PA in accordance with scheme Fig. 1b. Cytotoxicity was assessed using alamarBlue assay. The data were normalized to control values (no fatty acid and IONP exposure), which were set as 100% cell viability. Control cells were untreated. Data are expressed as mean ± SEM (n = 3). (**) P < 0.01 denote significant differences.
