In this study we consider the synthesis of silver nanoparticles from the aqueous leaf extracts of Phyllanthus maderaspatensis, which, we demonstrate, is a highly potential herb for the biosynthesis of NPs. Studies also indicated a gradual increase in the synthesis of NPs with time, thus proving the efficiency of P. maderaspatensis as an ideal catalyst in the formation of biologically synthesised phytonanoparticles. © 2014 Taylor and Francis Group, LLC.
