Abstract
The invention relates to a method for providing a surface with carboxyl groups. A compound is applied to the surface with at least one functional group which can be converted into a carboxyl group. Thereafter, this surface is treated with a plasma to immobilize the compound, and then the functional group is converted into a carboxyl group.
