Abstract


In recent years, green synthesis of metal nanoparticles is an interesting issue of the nanoscience and nanobiotechnology. There is a growing attention to biosynthesis the metal nanoparticles using organisms. Among these organisms, plants seem to be the best candidate and they are suitable for large scale biosynthesis of nanoparticles.  Nanoparticles produced by plants are more stable, and the rate of synthesis is faster than that in the case of other organisms. Moreover, the nanoparticles are more various in shape and size in comparison with those produced by other organisms. The present investigation was carried out to green synthesis of zinc oxide nanoparticles by using the medicinal plant Cassia auriculata(Tanners cassia).They were synthesized by mixing 1 mM aqueous of zinc acetate with aqueous extract of Cassia auriculataflower.The formation of nanoparticles was monitored by visualizing color changes and it was confirmed by Electron microscope (SEM), UV-Vis spectrophotometer and Fourier Transform Infra-Red (FT-IR) spectroscopy.The results of various techniquesconfirmed the presence Zinc oxide nanoparticles.

Keywords
