Forming immobilized nanostructured titanium dioxide having antibacterial properties

Synthesis, Characterization and Antibacterial Properties of Titanium Dioxide Nanoparticles

Effects of Solvent on the Structure and Properties of Titanium Dioxide Nanoparticles and Their Antibacterial Activity

Titanium dioxide is semiconductor metal oxide having many applications in photocatalytic activities, cosmetics and in the food industry. It exists in three major crystalline forms: anatase, rutile and brookite. The solvents play a major role in the synthesis, stability and morphology of the metal oxide nanoparticles. It affects both the phase and particle size of metal oxide. T...

Photocatalytic inactivation of Cryptosporidium parvum on nanostructured titanium dioxide films.

Control of waterborne gastrointestinal parasites represents a major concern to water industries worldwide. In developed countries, pathogens in drinking water supplies are normally removed by sand filtration followed by chemical disinfection. Cryptosporidium spp. are generally resistant to common disinfection techniques and alternative control strategies are being sought. In the current study, ...

Green synthesis of titanium dioxide nanoparticles using Psidium guajava extract and its antibacterial and antioxidant properties.

OBJECTIVE To determine the efficacies of antibacterial and antioxidant activities of aqueous leaf extract of Psidium guajava mediated biosynthesis of titanium dioxide nanoparticles (TiO2 NPs). METHODS Synthesized TiO2 NPs were tested by disc diffusion method against against human pathogenic bacteria. The total antioxidant activity and phenolic content (Folin-Ciocalteau method) of synthesized ...

Antibacterial Properties of Visible-Light-Responsive Carbon-Containing Titanium Dioxide Photocatalytic Nanoparticles against Anthrax

The bactericidal activity of conventional titanium dioxide (TiO₂) photocatalyst is effective only on irradiation by ultraviolet light, which restricts the applications of TiO₂ for use in living environments. Recently, carbon-containing TiO₂ nanoparticles [TiO₂(C) NP] were found to be a visible-light-responsive photocatalyst (VLRP), which displayed significantly enhanced antibacterial properties...
