Abstract
The word bio reduction of cu nanoparticles has attracted the minds of young researchers because of the need in developing an economical and efficient synthesizing technique. We put forward the green, a biogenic approach for the synthesis of Copper nanoparticles using the leaf extract of leucas aspera. Leucas acts as a potential reducing and stabilizing agent for the synthesis of copper nanoparticles. The biomolecule present in the leaf extract induce the reduction of copper ions from Copper Sulphate as a result of which leucas conjugated nanoparticles are formed. The first confirmation for the formation of copper nanoparticles was the physical colour change (yellow to green). Which was then confirmed by UV visible spectroscopy demonstrated a peak at 579nm corresponding to plasmon resonance of copper nanoparticles Furthermore extending towards the implementation of the synthesized nanoparticle to the ease of mankind. The biomolecules present in leucas enhances the biological property of the leucas conjugated copper nanoparticles .Antioxidant stands as an important application of nanoparticle in the medical world the percentage of radical scavenging exhibited by leucas mediated copper nanoparticle proves that it can act as a efficient antioxidant (DPPH assay proved it) .Dye happens to be a hazardous substances to the environment, Methylene blue was reduced biotically by the action of leucas capped copper nanoparticles, the decreasing value of absorbance at 660nm confirms it.
