Biosensors have various applications in many areas, a very prominent example being blood glucose monitoring for diabetes treatment. For this application, commonly enzyme electrodes are employed, in which an electrochemical transducer is combined with immobilized enzymes. A key challenge in the design and operation of such devices is the biocompatibility of the transducer. In this work, we fabricated microelectrodes from boron-doped nanocrystalline diamond, characterized by excellent biocompatibility and superior electrochemical properties. Furthermore, we investigated the modification of the electrodes with functional redox polymer brushes, which allowed a stable immobilization and the electrical “wiring” of enzymes.
