GREEN SYNTHESIS OF COPPER OXIDE NANOPARTICLE USING CURCUMA LONGA POWDER AND ITS CHARACTERIZATION

Abstract

Nanotechnology is a rapidly advancing interdisciplinary field that has numerous applications in both academia and industry. It involves the creation and analysis of novel materials at the nanoscale. Recent breakthroughs in nanotechnology have given rise to the development of engineered nanoparticles, which have opened up new possibilities in various sectors such as electronics, optics, energy, biomedicine, and more. Metal and metal oxide nanoparticles, in particular, have gained significant attention and find applications in research institutes and industries. Researchers are increasingly interested in green nanotechnology, which focuses on creating nanoparticles using environmentally friendly and cost-effective methods. Among metal oxide nanoparticles, copper oxide nanoparticles pose itself as an attractive candidate due to its distinguishing properties and varied applications. Traditionally, these nanoparticles are synthesised using physical and chemical approaches which are known to be expensive and significantly harmful to the environment. Thus, employing a green synthesis approach to produce copper oxide nanoparticles is better for the environment and additionally provides the benefit of being cost effective. The study describes how powder extract from readily available plant material, Curcuma longa, can be used to produce copper nanoparticles. Various techniques such as Anti Bacterial Assay, UV-VIS spectrophotometry, Fourier transform infrared spectroscopy (FTIR), were employed to characterise the biosynthesized copper nanoparticles.
