All DropletSens™ products use a proprietary microfluidic liquid reagent based approach to measure analytes in water.
In our nanodroplet microfluidic sensors, sample is autonomously drawn into the device through an inlet filter, injected into a stream of oil and mixed with one or more reagents. The oil leads to the formation of segmented aqueous nanodroplets in which the water sample and reagents mix very efficiently, resulting in colour formation, which is detected and quantified. Via stored calibration curves, an analyte concentration can then be determined.
Bringing the lab to the water
The nanodroplet microfluidics approach allows us to build compact sensors that after initial set-up draw in and analyse water samples autonomously for continuous operator-free monitoring, providing a convenient means of bringing the lab to the water, to help manage this precious resource where it matters.
