Increasing use of silver nanoparticles (AgNPs) in various fields as mentioned recently like cosmetology, clinical nanotechnologies and medicine causes the growth of a nontoxic and green synthesis methodology. The present study provided a facile stable one-step synthesis of AgNPs in the presence of Artemisia herba-alba, Mentha, Rosmarinus and Ranunculus aqueous oil extract as reductant and stabilizer via oil-in-water nano-emulsion.
