In this scinetific article we show thatby highly reactive oxyen plasma treatment we can rapidly alter surface chemistry of titanium nanotubes and produce different crystalinity, such as rutil or antase phase. The results are importaint as altered crystalinity of the surface can significantly influence on the biological response. It was shown that platelate adhesion is highly influenced by the altered in surface crystaline structure.

In this book chapter commonly employed vascular implants are presented as well as clinical conditions associated with such implants. Emphasis is given on nanostructured surfaces, especially on TiO2 nanotubes of different sizes and diameters, which could be used as support system for vascular implants. Surface modification techniques are further discussed especially plasma treatment, which was shown to significantly influence on the biological response. Moreover systematic in vitro studies with endothelial cells and platelets are presented providing valuable information on surface interaction with vascular implants. Chapter also deals with antibacterial properties of nanostructured surfaces and provides evidence that desired biological response could be achieved by fine tuning specific nanotopography and surface chemical composition by highly reactive oxygen plasma.

Formation of TiO2 nanotubes on titanium surfaces is a promising way to alter surface properties of titanium implants. However the stability of nanotubes and their surface properties could be altered after the use of common sterilization techniques. In this paper we show that autoclave sterilization destroys nanostructure of the surfaces, regardless of the nanotube size. While UV light sterilization and commercial H2O2 plasma and non-commercial oxygen plasma sterilization did not influence on nanotube morphology. Moreover the in vitro results of our study show that oxygen plasma treatment promotes proliferation of osteoblast like cells.

In the invited talk the treatment by electrochemical anodization and gaseous plasma were presented. Nanostructured surfaces obtained from electrochemical anodization were presented and gasous plasma tretament technique was presented as one of intresting approaches to modify the surface proeprties of Ti surface. The results of in vitro studies conducted with whole blood and endothelial cells were also presented.

The invited talk given on the scientific meeting was mainly focused on presentation of various types of surface finishing procedures, the most empahsis was given to the electrochemical anodization process and gaseous plasma treatment. Significant part of presentation was focused on the in vitro biological response of surfaces treated by this methods. The possible application of such surface treatment techniques for the 3D printed parts of implants was also discussed, as 3D printing technologies gained significant importance in medicine and are alreadly vastly used in the ortopaedic surgeries.
