Figure 10. Photo-activated Ag/TiO2 NPs (silver-modified TiO2 nanoparticles) induced DNA laddering in the MDA-MB-231 (human breast adenocarcinoma, highly invasive) cell line. Representative patterns of DNA laddering in (A) MCF-7 (low metastatic potential) and (B) MDA-MB-231 cells. Cells treated for 24 h with cisplatin (0.8 mg/ml) were used as positive controls for the induction of DNA laddering.
