“…The ultimate effect is an increase in oxygen vacancies in the TiO 2 lattice to compensate the charge neutrality, thus promoting antase-to-rutile transformation in doped samples1264. However, such concept does not take into account of the diffusion and agglomeration processes of silver nanoparticles during the annealing treatment, as observed in this and other studies196566.…”

The effect of silver on the phase transition and microstructure of titanium oxide films grown by pulsed cathodic arc had been investigated by XRD, SEM and Raman spectroscopy. Following successive thermal annealing up to 1000 °C, microstructural analysis of annealed Ag-TiO2 films reveals that the incorporation of Ag nanoparticles strongly affects the transition temperature from the initial metastable amorphous phase to anatase and stable rutile phase. An increase of silver content into TiO2 matrix inhibits the amorphous to anatase phase transition, raising its temperature boundary and, simultaneously reduces the transition temperature to promote rutile structure at lower value of 600 °C. The results are interpreted in terms of the steric effects produced by agglomeration of Ag atoms into larger clusters following annealing which hinders diffusion of Ti and O ions for anatase formation and constrains the volume available for the anatase lattice, thus disrupting its structure to form rutile phase. The effect of silver on the optical and wetting properties of TiO2 was evaluated to demonstrate its improved photocatalytic performance.

“…This devastating complication may result in chronic suffering and extremely huge medical expenses [11,12]. Therefore, it is highly desirable to introduce antimicrobial agents into implant surfaces to provide antibacterial activities and prevent peri-implant infections [13][14][15][16][17]. In comparison with organic antibiotics, inorganic antibacterial metal elements (e.g., silver (Ag) [18][19][20][21][22], copper (Cu) [23][24][25][26] and zinc (Zn) [27][28][29]) have attracted great attention due to their perfect stabilities, superior broad-spectrum antibacterial properties, relatively low toxicity to human cells and low risk of producing resistant strains [30,31].…”

Ti and its alloys are the most commonly-used materials for biomedical applications. However, bacterial infection after implant placement is still one of the significant rising complications. Therefore, the application of the antimicrobial agents into implant surfaces to prevent implant-associated infection has attracted much attention. Scientific papers have shown that inorganic antibacterial metal elements (e.g., Ag, Cu, Zn) can be introduced into implant surfaces with the addition of metal nanoparticles or metallic compounds into an electrolyte via micro-arc oxidation (MAO) technology. In this review, the effects of the composition and concentration of electrolyte and process parameters (e.g., voltage, current density, oxidation time) on the morphological characteristics (e.g., surface morphology, bonding strength), antibacterial ability and biocompatibility of MAO antimicrobial coatings are discussed in detail. Anti-infection and osseointegration can be simultaneously accomplished with the selection of the proper antibacterial elements and operating parameters. Besides, MAO assisted by magnetron sputtering (MS) to endow Ti-based implant materials with superior antibacterial ability and biocompatibility is also discussed. Finally, the development trend of MAO technology in the future is forecasted.

“…For example, CNT-doped TiNT on glass by dip-coating [11], Ag/TiO 2 composite films [12], CdS/Pt-TiNT [13] and highefficient CdS/TiNT films [14] on the Ti substrate have been reported. However, most of these surfaces showed either low-effectiveness under illumination by bright light or were toxic due to the application of CdS.…”

“…In the past decade, to avoid the cleaning of tested solutions, immobilization of the TiO 2 -based photocatalyst species onto various substrates have been proposed [11][12][13][14]. For example, CNT-doped TiNT on glass by dip-coating [11], Ag/TiO 2 composite films [12], CdS/Pt-TiNT [13] and highefficient CdS/TiNT films [14] on the Ti substrate have been reported.…”

Nanoparticulate surfaces possessing antimicrobial and fungicidal properties under visible light illumination have found wide applications in a number of fields. In this study, titania nanotubes, as well as titania compact films were designed with pure Cu 2 O crystals in a mildly acidic copper acetate solution using a simple alternating current (AC) deposition approach. In this way, the thermally oxidized Ti substrate was coated by densely packed pyramidal and bipyramidal shaped Cu 2 O crystals with dominant (111) planes and investigated against several types of fungi and bacteria. For comparison, TiO 2 nanotube (TiNT) films were also decorated with similar crystals and tested. The results showed that, compared to bare TiO 2 films, both Cu 2 O-inTiNT and Cu 2 O-on-TiO 2 heterostructures exhibited remarkably enhanced activity against tested fungi and bacteria. We also demonstrated that the high photoactivity of these crystals remained even after 50 h stability tests under bright light illumination. The results obtained from in vitro tests indicated that Cu 2 O-in/on-TiO 2 heterostructures show promise as visible light driven antimicrobial materials.
