A new diabetes test – level 3
Australian scientists say that they’ve developed the ’holy grail’ of blood sugar testing for diabetics. A non-invasive strip checks glucose levels through saliva.
Scientists have developed a way of embedding an enzyme that detects glucose directly into a transistor, which is a very sensitive amplifier. The enzyme turns glucose into a signal that the transistor can detect. The transistor can be manufactured at a low cost using simple printing techniques because the electronic materials are all inks.
Scientists believe that this test is going to radically change the way we think about medical devices and sensors in particular. At the moment, the test is going to start clinical trials before it can be manufactured at a large scale.
Difficult words: holy grail (something that people want very much to have or achieve), embed (to fix firmly and deeply in a surrounding solid mass), enzyme (a substance in the body that helps it work), amplifier (an electronic device that increases the power of a signal).
