AbstractThe potent antimicrobial efficacy of nanoparticles compounds represents new solution to microbial challenges in many infectious diseases. In the present study TiO2 nanoparticles which prepared by sol-gel method with 33nm size posses marked antibacterial effect on gram positive Staphylococcus aureus strain and gram negative Escherichia coli strain. The minimum inhibition concentration of TiO2 nanoprticles was found to be 30 μg/ml for S. aureus and40μg/ml for E. coli, which was determined by broth dilution method with and without TiO2 nanoparticles. The results were confirmed by agar diffusion assay.
