Abstract: The green synthesis of Copper and Lead nanoparticles were synthesized using ZingiberOfficinale stem extract. The stem extract acts as both reducing and capping agent. The synthesized Copper and Lead nanoparticles were confirmed by the change of colour after addition of stem extract into the Copper Sulphate and Lead Sulphate solution. The biosynthesized Copper and Lead nanoparticles were characterized by using UV-Visible analysis, X-ray diffraction analysis (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray analysis (EDX). From UV-Visible analysis, Copper and Lead nanoparticles shows the characteristic absorption peak at 208nm and 239nm. From the XRD, it was found that the average particle sizes of both nanoparticles were found to be 3nm.
