Background: Silver nanoparticles (AgNPs) are toxic to microorganisms and can potentially kill multidrug-resistant bacteria. Nanoparticles be synthesized in many ways, such as physical or chemical methods. Recently, it has been found that plant molecules perform the same reduction reactions necessary for production of but a much more efficient way. Results: Here, green chemistry was employed syn...
