Synthesis And Antibacterial Activity Of Zno And Fe Incorporated Zno: A Comparative Study

Abstract

Oxide nanocomposites have attracted much attention due to their potential application in environmental remediation. Among various semiconductor system, Zinc Oxide (ZnO) has been widely used for competent disinfection and antimicrobial activity. Reports reveal that by incorporation of foreign particles may modify the host material by inducing favourable properties. In the present study, ZnO and Fe incorporated ZnO were synthesized by sol-gel co-precipitation method. Synthesized material was characterized by X-Ray diffraction (XRD) for crystalline structure, UV spectroscopy for optical behaviour, scanning electron microscopy and energy dispersive spectroscopy for morphological and elemental investigation. Various characterizations show the formation of hexagonal wurtzite phase of ZnO and Fe incorporated ZnO. To investigate the antibacterial properties of ZnO and Fe doped ZnO, two gram negative bacteria (Escherichia coli, Pseudomonas aeruginosa) & two gram positive bacteria (Staphylococcus aureus Bacillus subtilis) were chosen and agar well diffusion method was adopted to investigate antibacterial activity. Compare to plane ZnO, Fe doped ZnO showed significant antibacterial activity.
