ABSTRACT
Biogenic synthesis of diverse nanoparticles via greener path has gained interest by researchers as they are eco-friendly, sustainable, and non-toxic. Present review article aims to update diversified copper nanoparticle (CuNPs) synthesis and their antibacterial activity thru greener method using different plant parts like leaves, fruits and roots. The phytoconstituents present in the plants acts as stabilizing and bioreducing agent for the synthesis of CuNPs. Various reports are available on the synthesis of CuNPs using precursors like copper sulphate, copper acetate and copper nitrate with different sizes of CuNPs ranging from 1-200 nm with spherical, rod and hexagonal shapes. CuNPs exhibited significant inhibition of gram positive and gram negative bacteria. This review highlights the synthesis of CuNPs using different parts of plants and their potential applications as antibacterial agents, which may act as a promising drug candidate through nano approach
