Surface structure and in vitro apatite-forming ability of titanium doped with various metals

Antibacterial properties of Cu-doped TiO2 prepared by chemical and heat treatment of Ti metal

“…Meanwhile, rutile, anatase, and metallic Ti (substrate) were detected in AL-Cu-HT. Enhancement of the anatase formation by Cu doping has also been reported [19]. Therefore, reasonable experimental results were obtained by the TF-XRD measurement.…”

“…Therefore, reasonable experimental results were obtained by the TF-XRD measurement. The compositions of the sample surfaces were analyzed by XPS, as per our previous report [19], which are summarized in Table 2. In both the samples, TiO 2 was the main component, and these results corresponded to the TF-XRD results (Figure 2 (b)).…”

“…Such materials prepared by the latter method exhibit antibacterial properties under visiblelight-irradiation conditions due to the reactive oxygen species formed by visible-light-responsive photocatalysis [17,18]. In our previous research, we established a technique to dope metal ions, including Cu ions, into the TiO 2 layer formed on Ti metal by modifying the alkaline-heat treatment method [19]. If a Cu-doped TiO 2 layer formed by the modified alkaline-heat treatment exhibits excellent antibacterial properties, then the material will be useful for dental applications, especially abutments.…”

Visible-Light-Enhanced Antibacterial Activity of Silver and Copper Co-Doped Titania Formed on Titanium via Chemical and Thermal Treatments

“…However, it is necessary to improve the antibacterial activity of N-doped or Cu-doped TiO 2 . One possible approach to achieve this is to increase the N or Cu content, but our method limits the amount of N or Cu that can be doped into TiO 2 to improve photocatalytic antibacterial activity and apatite formation ability [ 28 , 31 ].…”

Recent activities of titanium research and development in Japan

“…Preparation of TiO 2 layers on Ti and its alloys using processes like thermal oxidation [31], anodic oxidation [32], and NaOH treatment and heating [33] has been reported. Dual functionalization of both antibacterial activity and bone compatibility was oriented by using the TiO 2 layer as a visible-light active photocatalyst and carrier of metallic particles such as Cu, Zn, and Ag.…”
