“…The anodization process is a surface modification method that is usually used in case of titanium-based materials, but anodization can be applied to a large number of metallic materials in order to obtain nanostructured surfaces. The equipment for anodization consists of a cell with two or three electrodes: titanium-based materials as the anode and working electrode, platinum as cathode and counter electrode and when the cell has three electrodes, the Ag/AgCl electrode is used as a reference electrode [12]. The advantage of the anodization process is the ability to make the nanostructured formation with a direct connection to the substrate.…”

Implant surface properties define the interaction of the implant with the surrounding tissue. To obtained advanced biological, mechanical and physical properties, metallic implants are often exposed to different kinds of surface modification. The electrochemical anodization process is an efficient method for nanostructured surface modification, which leads to the formation of nanotubular oxide layers on metallic surfaces. These obtained layers could be applied in biomedicine due to their chemical stability, biocompatibility and non-toxic nature in the human body. As a part of different kinds of medical implants such as dental implants, artificial hip joints, bone plates, screws, spinal fixation devices or stents, an oxide layer significantly increases cells adhesion and plays a significant role in improving the rate of osseointegration. However, an important topic in research of implants with a nanotubular oxide layer is integrity during fixation and exploitation and possible damage initiation and development. This review article aims to present the application of nanotubular oxide layers in biomedicine and to explain their influence on the biocompatibility and osseointegration of medical implants. Influence of the layers properties, such as roughness or contact angle, and the influence of their morphology on biocompatibility and osseointegration, as well as the influence of fixation and exploitation on the damage of the nanotubular oxide layer, are considered.

Commercially pure titanium (cpTi) and titanium alloys are the most commonly used metallic biomaterials. Biomedical requirements for the successful usage of metallic implant materials include their high mechanical strength, low elastic modulus, excellent biocompatibility and high corrosion resistance. It is evident that the response of a biomaterial implanted into the human body depends entirely on its biocompatibility and surface properties. Therefore, in order to improve the performance of biomaterials in biological systems modification of their surface is necessary. One of most commonly used method of implant materials surface modification is electrochemical anodization and this method is reviewed in the present work.Aim of the presented review article is to explain the electrochemical anodization process and the way in which the nanotubes are formed by anodization on the metallic material surface. Influence of anodizing parameters on the nanotubes characteristics, such as nanotube diameter, length and nanotubular layer thickness, are described, as well as the anodized nanotubes influence on the material surface properties, corrosion resistance and biocompatibility.

“…A double-or multi-layered nanoarchitecture is an interesting target with respect to the application of the nanotube layer in photovoltaic cells and bioengineering areas. Such multilayered TNTs were previously synthesized (Portan, Papanicolaou, Jiga, & Caposi, 2012); their manufacturing process represented a big challenge for the electrochemistry community. Figure 27.7(a) shows an SEM image of superimposed TNT layers.…”
