Root and shoot uptake of synthesized nano Zno and its impact on differences in bio-availability during exposure in aqueous suspension

Abstract

The proposed study highlights on the synthesis of Zinc oxide nanoparticles using chemical and green methods. In the field of nanotechnology Green synthesis is an eco-friendly development. The synthesis of ZnO is carried out using leaf extract of Azadirachta indica (neem) as a reducing agent. The synthesised products were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Analysis (EDAX). The present work is to investigate the effect of chemical and green synthesized zinc oxide nanoparticles on germination and growth of Lycopersicon esculentum (tomato) using petriplate seed germination method. The impact of concentration of applied ZnO nanoparticles via green synthesis and chemical methods were analyzed. It was observed that the growth of Seedling is maximum for green synthesized zinc oxide nanoparticles at appropriate concentration over chemically synthesized zinc oxide nanoparticles, bulk ZnO and control. Hence the green method is found to be more effective.
