Plant mediated synthesis or green synthesis of nanoparticles is gaining importance due to its simplicity, eco-friendly nature, rapid rate of synthesis, less cost and due to the disadvantages associated with chemical synthesis. The bio-active molecules present in the plant extracts are utilized for the synthesis of zinc oxide nanoparticles from its bulk molecules. | Green synthesis of zinc oxide nanoparticles using neem (Azadirachta indica) and Tulasi (Ocimum tenuiflorum) leaf extract and their characterization
