Synthesis, characterization and anti-bacterial screening of complex nanocomposite structures of SiO2@ZnO@Fe3O4 and SnO2@ZnO@Fe3O4

In this research paper, the synthesis was aimed at the development of complex nanocomposites of SiO2@ZnO@Fe3O4 and SnO2@ZnO@Fe3O4. These materials were achieved through the chemical double co-precipitation technique. The nanocomposites were characterized by Powder X-ray Diffraction (PXRD), Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Selected Area Electron Diffraction (SAED), EDAX and Elemental mapping techniques. The developed nanocomposites were further evaluated by magnetic studies at room temperature. Also, the nanocomposites were subjected to antimicrobial studies. The minimum inhibitory concentrations indicated that the silica coated nanocomposite found better antibacterial activity due to is porous surface.
