Biosensor Principle for Detecting Chemicals in Water

Caption

The color sensor principle developed at the HZDR is based on a red and a green fluorescent dye. If a substance to be detected is present in a water sample, then the sensor shines green; a red color, however, indicates that the substance is not present.
