GREEN SYNTHESIS OF COPPER NANOPARTICLES USING ECLIPTA PROSTRATA LEAVES EXTRACT AND THEIR IMPACT ON SEED GERMINATION AND SEEDLING GROWTH OF SORGHUM VULGARE

Abstract

Nanotechnology is a vital and rapidly evolving breakthrough with a wide range of applications.It entails the mixing and application of materials with one of the measurements ranging from 1 to 100 nm. For the blending of nanoparticles, a variety of physico– synthetic techniques are presently being used (NPs). Nanoparticles' size, orientation, and physical features have been proven to alter the performance of any material. For several years, scientists have been experimenting with various nanoparticle synthesising processes. In contrast to chemicalmediated or green synthesis, the green technique of nanoparticle synthesis is simple, efficient,and environmentally benign. Chemical synthesis involves toxic solvents, high pressure, energy conversion, and high temperature. Microbial synthesis is not industrially feasible due to its laboratory maintenance. Since green synthesis is the best choice for nanoparticle synthesis, the focus of this research is on the cheapest and simplest way to synthesize copper nanoparticles using Eclipta Prostrata leaves extract. The synthesized lead nanoparticles were confirmed by Visible UV spectroscopy, XRD and particle size analyser. The toxicity was tested by studying the size of the 87 nm nanoparticles obtained, and the synthesized nanoparticles were used to
study seeds and the effects on growth. The antimicrobial activity of lead nanoparticles was analysed with pathogenic fungi, bacteria and adequate photographic algae. Synthetic nanoparticles showed an efficient antimicrobial activity against bacterial and pathogenic fungi.In the same way, synthetic nanoparticles showed an efficient activity against the aggregate to spirulina culture.
