Morphological damage and increased ROS production of biosynthesized silver nanoparticle against MCF-7 breast cancer cells through in vitro approaches

In this study of anti-cancer activity, the cytotoxicity effect of the silver nanoparticle was shown excellent anti-cancer activity against MCF-7 breast cancer cells. The IC50 concentration of the synthesized silver nanoparticle against performed MCF-7 breast cancer cells was 1000 mg/ml concentration. Further, the shape modifications in the silver nanoparticle treated MCF-7 cells were viewed by phase contrast micro-scope and proved after comparison with untreated control. Next, the intracellular proliferation, chro-matin condensation, granular membranes cleavage and surface layers damage were effectively seen by fluorescence microscopy using AO/EB fluorescence dyes. The failure of matured nucleus was clearly shown after the treatment of Ag NPs and was effectively proved by fluorescence microscope using Hoechst 33342 stain. Finally, the anti-cancer effect identification through various invitro experiments was clearly favored to performed silver nanoparticle, and suggested that the nanoparticle was very effec-tive against multi drug resistant bacteria, biofilm producing bacteria and cancer cells.
