Synthesis of Metallic Oxide Nanoparticles Using Cymbopogon citratus Through Conventional Sol-gel Method

Synthesis of Metallic Oxide of Nanoparticles

Abstract

Metallic oxide nanoparticles are synthesized through various methods for research and commercial purposes, with significant improvements observed over time. The sol-gel process is among the chemical methods employed for nanoparticle synthesis. Lemongrass (Cymbopogon citratus) was selected for synthesizing metallic nanoparticles using acetate salts of copper, cobalt and magnesium through the  conventional sol-gel method. This technique is relatively new for direct nanoparticle synthesis. The  nanoparticles have undergone characterization using various spectroscopic techniques (FT-IR, UV/Vis, SEM, EDS), along with the addition of their antibacterial activities. The EDS spectra have been confirmed through EDS mapping for all nanoparticles. The antibacterial activities of these nanoparticles have also exhibited a positive response to E. coli bacteria, revealing clear zones of inhibition against the tested micro- organisms.
