ABSTRACT

Synthesis of nanoparticles by using plants is green synthesis also called biosynthesis that is ecofriendly as well as low cost. Naturally available precursor in the form of plants extract is used. In our research we used four different plants such as Curcuma longa, Ocimum sanctum, Azadirachta indica and Momordica charantia that are easy to cultivate and also available everywhere. By using above mentioned plants we synthesize Copper nanoparticles (CuNPs). The nanoparticles synthesized from chemical methods are medically non applicable because of contamination from precursor chemicals. In this present study all four plants were taken to investigate their potential for synthesizing CuNPs. These nanoparticles synthesized were confirmed by their change of colour due to the phenomenon of surface plasmon resonance. The characterization studied was done by UV-Vis spectroscopy and FTIR spectroscopy. All the four plants synthesized CuNPs showed good antimicrobial activity against S.aureus and A.niger.
