Many attentions have been paid to the beneficial effect of alkali-treated titanium to bioactivity and osteogenic activity, but few to the other biological effect. In this work, hierarchical micro/nanopore films were prepared on titanium surface by acid etching and alkali treatment and their biological effects on bacteria, cancer cells and mesenchymal stem cells were investigated. Gram-positive Staphylococcus...
12.8mol% calcia-zirconia coatings with nanostructured surface were prepared using plasma spraying technology. The bioactivity, cytocompatibility as well as their correlation with the surface topography and nanostructure of coatings were explored. Simulated body fluid (SBF) immersion test shows that the as-sprayed zirconia coating can induce apatite precipitation on its surface, whereas the heated...
The materials surface plays an extremely important role in the response of the biological environment to the artificial medical devices. The initial protein interactions with implant surfaces are very important and therefore, it is clear that if the surface morphology, structure, composition, and properties are changed, cell functions are influenced. Nanoscale materials are thought to interact with...
