Synthesis of Ultra Small Nano-TiO2 and their Antibacterial Activity under Dark and UV Light

Ultra small and uniform TiO2 nano particles were synthesized via simple and economical chemical bath deposition method. The synthesized nano-TiO2 particles were characterized by powder X?ray diffraction (XRD), Scanning Electron Microscopy (SEM), FT-IR spectroscopy (FTIR) and transmission electron microscopy (TEM). XRD and TEM analysis reveals spherical TiO2 nanoparticles exhibits anatase phase with the average size range of 6-8 nm. Further antibacterial activity of the synthesized TiO2 nanoparticles were tested against human pathogenic microorganisms including bacterial and fungi under dark and UV light conditions. From the results of the assessment of antibacterial activity of TiO2 exhibited promising antibacterial agents. In addition nano TiO2 can be preferable to use in Ointments and Bandages for skin infections
