MANUFACTURING AND CHARACTERIZATION OF TiO2 NANOTUBES ON PURE TITANIUM SURFACES FOR ADVANCED BIOMEDICAL APPLICATIONS

The purpose of the present work is to describe a technique of producing TiO2 nanotubes on pure titanium surfaces and to present some parameter affecting their geometry and surface density. Apart from this, the paper describes possible applications of TiO2 nanotubes to different branches of technology and especially to biomedicine. In the present investigation TiO2 nanotubes were created on pure titanium surfaces through anodizing method trying different types of electrolytes. The samples were analysed by SEM for defining surface parameters characteristics. Studies about the mechanism of attachment of the osteoblasts on the surface of titanium nanotubes were realized through the viscoelastic hybrid interphase model. Combining experimental procedure of creation of the nanotubes and SEM analysis, as well as the mathematical calculations for the nanotubes-osteoblasts interphase, data were derived about the required characteristics of TiO2 nanotube surfaces that could be used in order to design a new material for biomedical applications.
