Nanotech Breath Sensor Prototype to Detect Diabetes and Potentially Serious Complication

Nanotech Breath Sensor Prototype to Detect Diabetes and Potentially Serious Complication: Scientists are reporting development and successful testing of a sensor that can instantly tell whether someone has Type 1 diabetes. It could also be used by emergency room doctors to determine whether a patient has developed diabetic ketoacidosis. This new sensor can detect acetone in extremely moist air, an attribute that is critical for any breath test. It is sensitive enough to detect acetone at 20 parts per billion, a concentration that is 90 times lower than the level at which it can be found in the breath of diabetic patients.
