Abstract:
A detection device for detecting a marker in a liquid, preferably a fuel, comprising: a reaction chamber 5, provided with a de-dopable conductive polymer 6 building a path between two conductive pads 10 connected to a resistivity measurement device, wherein the de-dopable conductive polymer 6 is able to be de-doped by a chemical reaction with the marker, changing its resistivity.
