1. A method of producing an enzyme electrode arrangement, comprising:
- providing a substrate with a surface roughness in the range of 10 nm to 10 microns;
depositing a metal electrode layer onto the substrate;
depositing a semipermeable membrane in a thickness in the range of 10 nm to 100 nm; and
depositing at least one enzyme membrane;
wherein the method further comprises creating the surface roughness by providing a preprocessed master and subsequent replication by application of a fluid polymer precursor to the master and curing of the polymer precursor to provide the substrate with the surface roughness in the range of 20 nm to 10 microns.
