Controlled formation of anatase and rutile TiO2 thin films

We discuss the formation of TiO2 thin films via DC reactive magnetron sputtering. The oxygen concentration during sputtering proved to be a crucial parameter with respect to the final film structure and properties. The initial deposition provided amorphous films that crystallise upon annealing to anatase or rutile, depending on the initial sputtering conditions.

Toxicity assessment of anatase and rutile titanium dioxide

Titanium dioxide nanoparticles (TiO 2 NPs), in the two crystalline forms, rutile and anatase, have been widely used in many industrial fields, especially in cosmetics. Therefore, a lot of details about their safety issues have been discussed by the scientific community. Many studies have led to a general agreement about TiO 2 NPs toxicity, in particular for anatase form, but no mechanism

nanoparticles below 40nm, anatase seemed more stable and transformed to rutile at greater than 973K [14]. Banfield et al found that prepared TiO 2 nanoparticles had anatase and/or brookite structures, which transformed to rutile after reaching a certain particle size [15]. Once rutile was formed, it grew much faster than anatase. They found

Only anatase-rutile containing samples, in contrast to the pure anatase samples, induced significant LDH leakage or mild DNA damage (Fpg-comet assay). Evaluation of the metabolic competence of the cells (WST-1 assay) revealed a highly significant correlation between the SSA of the anatase samples and cytotoxicity. The anatase/rutile samples showed higher toxicity per unit surface area than the
