Antibacterial Activities of Titanium Oxide Nanoparticles

Titanium dioxide nanostructures are promising material for optical and antibacterial applications. In this study, TiO 2 nanoparticles have been synthesized using facile microwave-assisted hydrothermal process. The optical properties and the structure of the synthesized TiO 2 nanoparticles were characterized using several techniques such as Transmission Electron Microscopy (TEM), UV measurements, Fourier Transform Infrared (FTIR), Energy and Dispersive X-ray Spectroscopy (EDXS), X-ray diffraction, Scanning Electron Microscopy (SEM), and Thermogravimetric (TGA). The antibacterial activity of TiO 2 nanoparticles were assessed against the pathogenic strain E. coli ATCC 8739 . The reported results indicated superior antibacterial activity of TiO 2 nanoparticles tested against the pathogenic bacteria, which reveals potential applications of TiO 2 nanoparticles in biomedical and medical fields.
