The ability to synthesize metal nanoparticles with different shapes and sizes is important to explore their applications in electronics catalysis sensors optical and biological devices. As most of these applications were governed by silver gold and platinum. However the high cost constraint of these metals restricted their applications in high volume production. Presently copper nanoparticles provided a good alternative of silver gold and platinum nanoparticles because of their lower cost and catalytic activity novel electronic optical and magnetic properties or have antibacterial and antifungal properties . Compared to other metal nanoparticles materials the synthesis of copper nanoparticles are more .
