In this study, nano composites of titanium dioxide and magnesium aluminate samples were synthesized using the chemical sol-gel method. Investigations are conducted on the antibacterial behavior of a low concentration of transition metal oxides like TiO2, with pre-transition metal oxides, such as MgO and Al2O3. The goal of the current work is to apply various nano composite samples of (TiO2)x and MgAl2O4, with 4 and 10 wt% of TiO2 in MgAl2O4, respectively, for antibacterial applications. The composite samples were examined using Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and the X-ray diffraction pattern. Gramme - positive bacteria S. aureus and B. subtilis, as well as gramme-negative bacteria P. aeruginosa and S. typhimurium, were tested for in the samples' antibacterial behaviour.
