Schematic of a generic biosensor architecture. The target analyte interacts with an immobilized bioreceptor layer, and the resulting molecular recognition event is translated by a physico-chemical ...

Scientists can do some nifty things with microbes, including engineering bacterial cells to sense and signal the presence of specific compounds. These microbial whole-cell biosensors have numerous ...

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, ...
