Copper nanoparticles were synthesized from green tea leaves extract. This method was proved to be an efficient method for the preparation of copper nanoparticles. The extract was prepared in deionised water. The extract was added to 10mMol of copper sulphate solution as 1:1 ratio and 0.5 m L- ascorbic acid was added as capping agent. The colour change of the solution indicates the formation of copper nanoparticles. The biosynthesized copper nanoparticles were characterized with the help of visual inspection, SEM (Scanning electron microscopy), EDX (Energy dispersive x ray spectroscopy). The size of the particle was found to be in the range of 60-80 nm. The synthesized copper nanoparticle efficiently inhibited various pathogenic organism. This method can be used for eco-friendly biosynthesis of copper nanoparticles.
