Conducting polymer based amperometric enzyme electrodes

The construction and the properties of conducting-polymer based amperometric enzyme electrodes are reviewed. The main aim is to focus on the properties of conducting polymer films which are important for the construction of amperometric enzyme electrodes. Additionally, the review is focused on electron-transfer pathways between conducting-polymer integrated immobilized enzyme molecules and the modified electrode using free-diffusing redox mediators as well as direct electron transfer via the conducting-polymer wires. Possible future applications using microstructured conducting-polymer films will be discussed.
