Abstract
In a sensor for measuring an analyte in a biological sample whose measuring surface is covered by or comprises a membrane, the membrane has free groups on the surface facing the sample. The surface is modified such that a hydrophilic component is immobilized on the surface in such a manner that chains of the hydrophilic component are chemically bonded to free groups on the surface. Thus, the surface is provided with a more hydrophilic character relative to its unmodified state.
