ANALYSIS OF CERAMIC IMPLANTS SURFACE WITH GOLDEN NANO-LAYER

Presented paper regards the research of the golden "nanocoatings" deposited on the plates made of zirconium oxide. Tests were carried out using a base material - zirconium oxide with a thin layer of gold. The coating thickness was about 10 microns. To investigation twelve samples were applied. Golden nanocoatings were prepared and analyzed in the Institute of Catalysis and Surface Chemistry - Laboratory of Surface Nanostructures. Investigations were divided into two stages: first - cells cultures toxicity tests and second - implantations to five adult male Wistar rats. All implants were tolerated in living organisms for a period of 5 months. All animals survived until the end of the experiment. Histological preparations obtained as a result of experiment and their analysis showed a good tolerance of implanted materials. Samples' surface examinations confirm high quality of golden coatings. Obtained results confirm necessity of further experiments with zirconium oxide as the base material and other biocompatible metals as the thin outside coating.
