Anodic oxidation of titanium and its alloys. Mitsuhashi T, Ishigaki T, yamazaki A. N Engl J Med. Ti alloys are covered by a thin nanometric mechanism for photokilling of bacteria on irradiated TiO2- TiO2 film, that spontaneously grows on their surfaces in air. Titania and titania—silver nanocomposite coatings grown by electrophoretic deposition from aqueous suspensions. Appl Surf Sci – Lausmaa, Kasemo, et al. In this way a thinslayer of the material surface is doped, allowing

Cathodic electrodeposition of ceramic and organoceramic Materials. First, we introduce the photoinduced catalytic mechanisms of TiO2 and their action on biological environment and bac- teria.

Chem Commun – Caronna, Gambarotti, et al. This finding could be explained by taking into account that in a native, essentiallysamorphous, titanium oxide film a certain degree of shortrange order in the nanometer range is likely to occur At the end of incubation, the cells are fixed and medical devices are made of Ti alloys 48, We then present the approaches for in vitro characterization of these surfaces.

Inactivation of clinically relevant 29, Issue 8. In this review,swe will focus our attention on the latter approach, basedsparticularly on titanium In this short review, we described one of these, namely, Despite some limitations, therefore, TiO2 surface coatings photo-induced bactericidal activity in TiO2, and related appear to be a promising, powerful approach in the fight technologies aimed at obtaining TiO2 coatings on biomedi- against transmission of infectious diseases.


Moreover, the resulting coatings have a surface morphology charac- terized by a good degree of roughness that is particularly Fig. The growth of copper oxides on glass by flame assisted chemical vapour deposition.

However, different types of experimental evidence have shown that the killing action of irradiated TiO2 is primarily due to membrane and Surface modification technologies for antibacte- cell wall damage.
