Abstract
Process for providing structures for an improved protein adherence on the surface of a body including the steps of a) providing a basic body made of titanium or a titanium alloy, b) acid-etching the basic body, c) storing the acid-etched basic body in an aqueous solution, whereby nanostructures are formed on the surface of the basic body, and d) drying the basic body with the nanostructures formed on its surface.

Process for providing structures for an improved protein adherence on the surface of a body, said process comprising
- a) providing a basic body made of titanium or a titanium alloy,
- b) acid-etching the basic body,
- c) storing the acid-etched basic body in pure water or an aqueous solution having a pH in a range of from 4 to 6 for at least two days, whereby nanostructures are formed on the surface of the basic body,
- d) drying the basic body with the nanostructures formed on its surface, and
- e) storing the basic body in a dry environment for at least one day after the drying according to d).
