Antibacterial Activities of Titanium Oxide Nanoparticles

Titanium dioxide nanostructures are promising material for optical and antibacterial applications. In this study, TiO2 nanoparticles have been synthesized using facile microwave-assisted hydrothermal process. The optical properties and the structure of the synthesized TiO2 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 TiO2 nanoparticles were assessed against the pathogenic strain E. coli ATCC® 8739™. The reported results indicated superior antibacterial activity of TiO2 nanoparticles tested against the pathogenic bacteria, which reveals potential applications of TiO2 nanoparticles in biomedical and medical fields.
