Abstract: We demonstrated size-controlled synthesis of silver nanoparticles (AgNPs) using Zizyphus mauritiana fruit extract from an aqueous solution of silver nitrate. The size distribution of the resulting AgNPs were found to be dependent on the concentration of fruit extract and reaction time, at the same concentration of silver nitrate. The AgNPs were characterised byUV-Visible spectroscopy (UV-Vis), particle size analysis (DLS), atomic force microscopy (AFM), transmission electron microscopy (TEM) and X- ray diffraction (XRD). The sizes of the AgNPs were found to decrease with the increase of concentration of fruit extract from 300 nm to 70 nm. The increase in reaction time from 5 min to 20 min significantly decreases the size of the AgNPs from 350 nm to 100 nm.
