A By using DAPI/TUNEL dual staining, Au NPs synthesized by Magnolia officinalis were determined to increase ROS-arbitrated apoptosis. B The cytotoxicity of biogenic Au NPs using bael fruit juice was studied against A549. C Anti-cancer ability of synthesized silver nanoparticle (Ag NPs) using phytochemical rich medicinal plant Lonicera japonica proved against A549 lung cancer cells by cell viability assay. D AO/EB staining of plant latex-capped silver nanoparticles in A549 (cells more dead cells (in red) and very few live cells (in green) in highest dose of LAgNP) exposed to (a) 0 μg/mL LAg NPs, (b) 1 μg/mL LAg NPs, (c) 10 μg/mL LAg NPs, (d) 20 μg/mL LAg NPs,(e) 50 μg/mL LAg NPs and (f) 100 μg/mL LAg NPs (A: under copyright (CC BY) from Taylor and Francis, B, C and D under copyright (CC BY) from Elsevier)
