Synthesis and Characterization of Nano-Aluminum Oxide Via Biological and Electrochemical Methods


In this research work, the nanoparticles of aluminum oxide were synthesized by two ways. The first way is the biological by using (Pseudomonas aeruginosa) bacteria with a rate diameter (102.35) nm. The second way is the electrochemical with a rate diameter (62) nm. These nanoparticles were characterized by Atomic Force Microscopy (AFM), X-Ray diffraction technique (XRD), Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM). Alumina nanoparticles are thermodynamically stable particles over a wide temperature range. The biological activity of these nanoparticles toward different species of pathogenic bacteria (Staphylococcus aureus) and (Pseudo monas) has been investigated. The nanoparticles prepared by chemical way was more effective in the inhibition of bacteria compared with that nanoparticles prepared by biological way.
