Biosynthesis of Eudrilus eugeniae vermi wash based enzyme decorated copper oxide nanoparticles towards seed germination of green gram

Abstract

The present investigation explore the biosynthesis of copper oxide nanoparticles (CuO NPs) by simple Co-precipitation method using Eudrilus eugeniae vermi wash and its applications to the seed germination of green gram (Vigna radiata). UV–Visible Spectroscopy and Fourier Transform Infrared Spectroscopy (FTIR) confirm the formation of CuO and its interaction with the functional group of enzymes present in the vermin wash. X-ray Diffraction, Scanning Electron Microscopy; Energy Dispersive X-ray analysis reveals the crystalline structure morphology, and elements of the CuO NPs. In order to evaluate the bio-potential properties of CuO NPs, a seed germination studies were carried out with green gram (V. radiata) with different concentrations of CuO NPs, and the result reveals that CuO NPs show a positive influence on the germination of green gram.
