New technology to monitor drug therapy at home (IMAGE)
Caption
The sensing principle of these sensors is straightforward: the molecular target or drug to be monitored (shown in green in the illustration above) can interact with a specific DNA molecule, called aptamer (yellow molecule). Upon binding to the molecular target, this “aptamer” DNA can no longer inhibits another electro-active DNA (red DNA), that can then reach the surface of an electrode and generate an electrochemical current easily detectable with an inexpensive reader.
