Synthesis And Characterisation of Copper Nanoparticles Using Aqueous Leaf Extract of Lagerstreomia Speciose and Their Biological, Antioxidant and catalytic activities

Abstract

Nanotechnology is gaining importance at tremendous rate in every field of science and technology. Researchers have developed a large number of different methods for the synthesis of nanoparticles; among this green route method is of great importance as it is eco-friendly and cost-effective. In this study we synthesized copper nanoparticles through green synthesis using a plant called lagerstroemia speciose. The formation of copper nanoparticles has been observed due to change in colour of extract solution. The sample solution was characterized by different techniques in order to find out the various physiological parameters like shape, size and nature of bonding. Plant extract acts as both reducing and capping agent .The various instruments used for characterization are DLS (Dynamic Light Scattering), SEM (Scanning Electron Microscopy), X-ray Diffractometry (XRD) and Fourier Transform-Infrared (FT-IR). Cups obtained were of size 35nm. The synthesized copper nanoparticles were studied for their anti-microbial activity, antioxidant, antidiabetic and catalytic activities and cytotoxicity.
