Production, Characterization, and Cytotoxicity Effects of Silver Nanoparticles from Brown Alga (Cystoseira myrica)

Figure 6

Cytotoxic effect on breast carcinoma cell line MCF-7 (a) and human hepatocellular carcinoma cell line HepG2 (b) treated with various concentrations of silver nanoparticles (from 0.1 to 100 μg/ml) synthesized by extract of Cystoseira myrica compared to breast carcinoma cell line and HepG2 human hepatocellular carcinoma cell line free from any treatment (control) after 48 hours of time exposure [different letters represent the significance between different groups and same letters express the nonsignificance between different groups].
