“…It was shown that silver or gold particle decoration led to a significantly higher photocatalytic activity [155]. The same increasing of photoactivity was also obtained by applying an external anodic voltage [156]. These facts suggest that in case of investigated objects, a valence-band mechanism dominates, and the observed accelerating effects have a common origin in increased band bending, either by applied voltage or by the junction formation [157].…”

The research efforts in understanding the influence of TiO 2 1D nanoarchitecture structure and morphology on its biological and photocatalytic activity absorbed a lot of attention during last few years. Nowadays, the application of TiO 2 coatings in biomedical technologies (e.g., in modern implantology) requires the material of strictly defined structure and morphology, possessing both high biocompatibility, as well as antimicrobial properties. The presented review is a compilation of interdisciplinary knowledge about the application of 1D TiO 2 nanostructural coatings (nanotubes, nanofibres, nanowires) in biomedical technologies. The methods and parameters of their synthesis, and the physicochemical techniques used in the characterization of their structure and morphology, are discussed. Moreover, their ability to be applied as innovative coatings for modern implants is presented.

“…It was shown that particle decoration with silver or gold led to a significantly increased photocatalytic activity, [325] and that also applying an external anodic voltage drastically enhances the photocatalytic activity. [138,389] These findings suggest that in the investigated cases, a valence-band mechanism dominates, and the observed accelerating effects have a common origin in increased band bending, either by junction formation or by the applied voltage. [38] To increase the photocatalytic activity, various mixedoxide tube layers were used, such as TiMo or TiW.…”

TiO(2) is one of the most studied compounds in materials science. Owing to some outstanding properties it is used for instance in photocatalysis, dye-sensitized solar cells, and biomedical devices. In 1999, first reports showed the feasibility to grow highly ordered arrays of TiO(2) nanotubes by a simple but optimized electrochemical anodization of a titanium metal sheet. This finding stimulated intense research activities that focused on growth, modification, properties, and applications of these one-dimensional nanostructures. This review attempts to cover all these aspects, including underlying principles and key functional features of TiO(2), in a comprehensive way and also indicates potential future directions of the field.

“…Numerous methods are available for the development of TNT, which includes anodization [55][56][57][58][59][60][61][62][63][64][65], sol-gel method [66][67][68][69], template method [70][71][72], hydrothermal method [38, [73][74][75][76][77][78][79][80][81], sonoelectrochemical [82][83][84][85], micro-wave irradiation [86,87], and alkaline synthesis [88]. Hoyer [89] was first reported the synthesis of TiO 2 -based nanotubes via template-assisted synthesis.…”

In this article, influence of anodization parameters on the formation of tubes, tube dimensions, formation mechanism, properties of TiO 2 nanotubes (TNT), and their applications in biomedical field are reviewed. The fabrication of TNT of a different shape such as pore size, length, and wall thickness by varying anodization parameters including electrolytes, pH, voltage, electrolyte bath temperature, and current density is examined and discussed. The crystallographic nature of the nanotube obtained by various methods has also been discussed. Finally, the article concludes by examining the key properties including the corrosion aspect and various applications in biomedical field in depth.
