| Description
| - The objective of the work was to prepare and characterize titania sol-gel coatings on non-porous titanium and titanium alloys. Titanium substrates (Ti, TiSi5, TiSi10) were mechanically tretated. Basic titania sol contained two forms of silver (AgNO3, Ag3PO4). Titania sol without silver was used as a reference sample. Coatings were prepared by dip-coating technique during stirring and fired at 400°C. Coatings after firing were characterized by electron microscopy. All titania coatings were measured to determine their adhesive and bactericidal properties. Adhesion of the coatings to the substrate was measured by tape test (ASTM D 3359-2), where the cut area was evaluated visually by optical microscope. Gram-negative bacteria E. coli (strain DBM 3138) was used for the bactericidal test. Coated substrates were imersed into suspension of E. coli in physiological solution for a period of 24 and 4 hours at laboratory temperature. Cytotoxicity of the materials was also tested. Coated substrates were leached in MEM growth medium for 1 day at 37°C and the extrats were added to mouse fibroblast (L929 cell line, ATCC(R) CCL-1TM). The cytotoxicity test (ISO 10993-5) was performed after one day and was based on the metabolic reduction of the soluble tetrazolium salt (WST-1) to a colored formazan.
