Viability of MCF-7 cells after 72 hours exposure to 20–100 µg.ml−1 of (a) GO or MGO, (b) walnut green husk extract, (c) Ag-GO-І, (d) Ag-GO-П and (e) AgNPs. (f) shows a summary comparison of cytotoxic activity of the nanomaterials after 48 hours exposure to 60 µg.ml−1. Triplicate incubations for each treatment were conducted in each independent experiment. P values were calculated using one-way ANOVA test (*P < 0.05).
