Highly pure nanostructured titanium dioxide was synthesized from a titanium foil via atmospheric-pressure plasma jet technique with electrolyte medium. The structures and morphology have been investigated and approved by X-ray diffraction, field emission scanning electron microscopy (FESEM) and energy dispersive x-ray diffraction (EDX). X-ray diffraction shows approve the titanium dioxide nanoparticles have a domain peak of crystallinity structure (anatase and rutile phase). Application of Titanium dioxide has been actively explored during last several years, the products of this nanoparticles were used to decontaminate and inactivate of Escherichia coli, Staphylococcus strain, and Pseudomonas aeruginosa clinical isolates as the alternative sterilizing approach. The main constituents include reactive oxygen species. These species can be useful to synthesize biologically important nanomaterials or can be used with nanomaterials for various kinds of biomedical applications to increase human health. Escherichia coli, Staphylococcus strain, and Pseudomonas aeruginosa were verified by applying the disk diffusion method, with titanium dioxide nanoparticles addition and found that the inhibition zone.
