As an associate fellow of the ITN project, I am not directly involved in the project itself. My work focuses on the development of self-powered glucose sensors based on enzymatic biofuel cells. Enzymatic biofuel cells use enzymes to convert the substrates, which are used as fuel (anode) and oxidant (cathode). The oxidation of the fuel at the bioanode generates electrons which can be used for the reduction of the oxidant at the biocathode. As result, the biofuel cell can operate without the need of external powered devices. For glucose detection, the glucose will be converted selectively by a glucose-converting enzyme at the bioanode. When combined with a non-limiting cathode, the power output of the biofuel cell is limited by the amount of glucose in the sample, which allows for its detection and possible quantification
