Green Engineered Biomolecule-Capped Silver Nanoparticles Fabricated from Cichorium intybus Extract: In Vitro Assessment on Apoptosis Properties Toward Human Breast Cancer (MCF-7) Cells. Biol Trace Elem Res. 2018 May 28;: Authors: Behboodi S, Baghbani-Arani F, Abdalan S, Sadat Shandiz SA Abstract The current experiment reveals the anticancer properties of silver nanoparticles (AgNPs) synthesized using aqueous leaf extract of Cichorium intybus, a significant medicinal plant. The characteristics of AgNPs were continuously studied by powder X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), zeta potential, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS) analysis. Current microscopic results show that produced AgNPs were spherical in shape with an average size of 17.17 nm. A strong peak between 2 and 4 keV showed the greatest ratio of the elemental silver signals, due to surface plasmon resonance (SPR). The AgNPs, fabricated by green method, had a negative zeta potential of - 9.76 mV, which indicates that the synthesized AgNPs is dispersed in the medium with high stability. The in vitro cytotoxicity effect of AgNPs showed promising anticancer activity against human breast cancer MCF-7 cells. Annexin V-FITC/propidium iodide assay, Hoechst 33258 staining, and upregulation of caspase 3 activity revealed significant apoptosis activities of AgNPs ag...
