Abstract

Screening of zinc oxide nanoparticles for cell proliferation synthesized through Adhatoda vasica nees

Nano science is the basic Study of systems and materials at the nanoscale. The objective of the present study focuses on the Phytoconstituent mediated biological synthesis of ZnO-NPs by Zinc acetate and sodium hydroxide by utilizing the biocomponents of leaves of Adhatoda vasica .The samples are characterized by UV-Vis Spectroscopy, Scanning Electron Microscopy (SEM), Energy Dispersive Xray (EDAX), X-ray diffraction (XRD) and FT-Raman Spectroscopy. The Synthesized ZnO-NPs were found to be discoid in Shape with an average size of 19 - 60 nm .The diffraction pattern also confirmed that the higher percentage of ZnO with fine particle size. Phytochemicals present in the plant were responsible for the quick reduction of Zn+ ion to metallic Zinc Oxide nanoparticles. The synthesized ZnO-NPs had the potential to mitigate the bacterial cell proliferation particularly Escherichia coli, Bacillus thuringiensis, Pseudomonas aeurogonisa and Staphylococcus aureus. Adhatoda vasica is a good source for rapid reduction of metallic Zinc oxide in to nanoparticles with antibacterial activity. These green synthesized ZnO-NPs are possess therapeutic values.
