Nanostructured TiO2 as the surface for the investigation of cell behaviour

This thesis deals with the study of cells on nanostructured surfaces of titanium dioxide, which are produced by the electrochemical method called anodic oxidation. The theoretical part is formed by an overview of manufacturing nanostructured surfaces using anodic oxidation method. It mentions the influence of external factors on the geometric parameters of the structure and description of methods of characterization structures. Furthermore there is processed outline of use for biomedical application and the description of interaction of the cell with surface. The practical part includes description of the production of nanoporous and nano-tubular structures made on thin films of titanium by direct method of anodic oxidation on which was studied the influence of external factors. Described a procedure and production of nanorods structures and nanodots generated using alumina template (AAO) which is subsequently carried out the study of the behavior of cells, which includes tests of adhesion, examination of morphology of cells, assays of proliferation and differentiation. Structures are under investigation of the interaction of cells with the nanostructured layer compared with the smooth surface of the titanium dioxide
