Abstract
- Owing to their anticancer effects and tremendous potential in medicine, green synthesis of silver nanoparticles (AgNPs) using plant extracts has gained considerable attention recently. In this study, silver nanoparticles (AM-AgNPs) were synthesized using Artemisia monosperma and their anticancer effects were tested against MCF-7 cells. The synthesized AM-AgNPs were characterized by UV–vis spectroscopy, Fourier transform-infrared (FT-IR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and X-ray diffraction (XRD) methods. The anticancer potential of AM-AgNPs was evaluated by MTT and NRU assays. Furthermore, mechanism(s) of anticancer effects of AM-AgNPs was assessed by cellular morphological damage, ROS production, and mitochondrial membrane dysfunction. Our results revealed that the AM-AgNPs were crystalline and face-centered cubic, with an average size of 24 nm. The green synthesized AM-AgNPs induced a significant decrease in cell viability by 13–86% in 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and 9–79% in neutral red uptake (NRU) assay at 10–100 μg/mL, respectively, indicating potent anticancer properties. The IC 50 value for both assays was nearly 32 μg/mL. Additionally, imaging studies revealed that AM-AgNPs triggered cell death. Furthermore, our results indicated that the anticancer activity exhibited by AM-AgNPs in MCF-7 cells was mediated by ROS generation and mitochondrial dysfunction. Overall, AM-AgNPs are excellent candidates for treating breast cancer.
