Alamar blue assay to assess the cell viability of HeLa, MCF7 and SKBR3 cells incubated with PEG-DSPE (control) and various O-GNR-PEG-DSPE (10–400 μg/ml) concentrations at (A) 24 and (B) 48 hour time points. Data are presented as mean ± SD (n = 6 per group). * = p < 0.05 between groups at that particular concentration.
