"Using the sol-gel method bioactive layers on basis of TiO2\u00A0, SiO2 and calcium phosphates will be prepared, their bioactivity in vitro will be established and possibillity of their modification by Ca2+ and Na+ will be verified.\u00A0In addition\u00A0active nanolayers based on TiO2 will be prepared on substrates of various types of materials. Besides TiO2 also layers combined with other oxides, layers with dispersed silver nanoparticles, doped by other additives, and hybrid layers where polydimethylsiloxane(PDMS) is used as polymer component, will be synthesised. Standard mechanical and chemical properties conditioning of practical using of the layers will be determined and their photocatalytic activity and antibacterial properties will be followed experimentally. Besides the issues oriented on practical using of the above layers also some data on microstructure, composition and texture of the layers will be obtained, mechanism of their formation will be completed and mathematical description of"@en . .
