In this work utilizing sol-gel process we synthetized Ag/TiO2-SiO2 nanomaterial containing 0.1, 1.0, 5.0, and 10% weight of silver. The samples were characterized with infrared (FTIR), Ultraviolet-visible (UV-VIS), Scanning Electron Microscopy (SEM), Z-Sizer and N2 adsorption-desorption. The Nanoparticles (NPs) were tested in ten different types of strains by studying Kirby-Bauer susceptibility. The results show that the nanoparticles exhibit antimicrobial activity at all concentrations. We determinate de Minimum inhibitory concentration (MIC) which shown that Candida albicans ATCC 10231 and Staphylococcus epidermidis NRS 101 showed the highest sensitivity to silver NPs at concentrations of 10 and 1%.
