摘要：

Objective:To formulate a simple rapid procedure for bioreduction of silver nanoparticles using aqueous leaves extract of Moringa oleifera(M.oleifera).Methods:10 mL of leaf extract was mixed to 90 mL of 1 mM aqueous of AgNOand was heated at 60-80 ℃ for 20 min.A change from brown to reddish color was observed.Characterization using UV-Vis spectrophotometry, Transmission Electron Microscopy(TEM) was performed.Results:TEM showed the formation of silver nanoparticles with an average size of 57 nm.Conclusions:M.oleifera demonstrates strong potential for synthesis of silver nanoparticles by rapid reduction of silver ions(Ag~+ to Ag~0). Biological methods are good competents for the chemical procedures,which are eco-friendly and convenient.
