Figure 5. Cytotoxicity effect of gold nanoparticles synthesised from R. rubescens (RR-AuNP) against lung carcinoma cell line A549 and Human lung fibroblast cells MRC-5 cells treated with different doses of RRAuNP. (A) Human lung fibroblast cells MRC-5 cells; (B) lung carcinoma cell line A549. Each bar represents mean ± SEM of three independent observations. Significant at *p < .05.
