Figure 6. Effect of (A) Ag/TiO2 NPs (silver-modified TiO2 nanoparticles) and (B) Photo-excited Ag/TiO2 NPs on the viability of MCF-7 (low metastatic potential) and MDA-MB-231 (human breast adenocarcinoma, highly invasive) breast cancer epithelial cells. *p<0.05 vs. negative control, based on the Kruskal-Wallis test. MTT assay was employed to determine cell viability. Data represent means±standard deviation from five independent experiments.
