Green Biosynthesis Silver Nanoparticles Using Leaf Extract

Using plant extract to synthesize silver nanoparticles is particularly worth of attention due to the simple, quick, affordable and friendly protocol with the environment. In our experiment, we have proved both the ability of common species (Mentha aquatic, Coleus blumei and Tagetes erecta) of achieving the synthesis of nanoparticles with a diameter between 8 and 300 nm, and the anti-bacterian effects of the obtained nano-silver.
