Green synthesis of silver nanoparticles using Hagenia abyssinica (Bruce) J.F. Gmel plant leaf extract and their antibacterial and anti-oxidant activities

Green synthesis of silver nanoparticles (AgNPs) was achieved by bio-reduction of silver nitrate using Hagenia Abyssinica plant leaf extract (HAPLE). The AgNPs formation was confirmed by Ultraviolet-Visible (UV-Vis) spectrophotometer. The synthesized AgNPs in solution have shown maximum absorption at...
