Antimicrobial Effect of Azadirachta indica, gum Stabilized Cobalt Doped ZnO Nanoparticles

Abstract

The wet chemical approach was used to synthesize the AI gum stabilized ZnO nanoparticles doped with Cobalt. The structural, morphological, antibacterial, and antifungal activity of AI stabilized at various cobalt concentrations were investigated. X-Ray Diffraction (XRD) pattern shows hexagonal form oriented on the c-axis. The presence of a spherical-shaped object has been confirmed using a Field Emission Scanning Electron Microscope (FESEM). Zinc, cobalt and oxygen atom’s presence is confirmed by Energy Dispersive X-ray (EDAX). Antibacterial activity on S.aureus reveals the maximum inhibition zone compared with the antibacterial activity of E. coli. Antifungal activity against Aspergillus fumigatus reveals the maximum inhibitory zone in contrast to Candida Albicans.
