Summary Nanomaterials are getting a great deal of attention because of their potential to achieve specific processes and selectivity, especially in biological and pharmaceutical applications including generation of bioactive compounds. TiO 2 nanoparticles because of their chemical stability, biological inertness and high stability are largely used in various fields. Thus, their toxicity evaluation becomes must. In the present study, TiO 2 nanoparticles were synthesized and characterized using TEM and XRD. Average particle size was estimated to be ∼18 ± 2 nm. Particles are agglomerated and mostly in spherical shape. TiO 2 nanoparticles were found to show inhibitory effect on the growth of E. coli bacterial strain in a dose dependent manner.
