Abstract

The microbial infection of biomaterials often causes clinic problems and sometimes even leads to the prosthesis failure. It is, therefore, important to prevent the biomaterials from bacterial contamination. This can be done by using anti-bacteria drugs. However, this method causes physiological burdens to the patients and does not always work. To stop the contamination from the just beginning is believed to be a better choice. The first step for infection is the attachment of bacteria on the material. In this work, the thin TiO2 nanotubes array films were constructed with totally different wettabilities showing either superhydrophobic or superhydrophilic. The bacterial attachment behaviors on them were evaluated. It is shown that the numbers of viable colonies on the superhydrophobic film were significantly less than those on the superhydrophilic one.
