New Sensor Detects Disease Biomarkers in Exhaled Breath
http://www.medgadget.com/wp-content/uploads/2016/04/Fujitsu-breath-sensor.jpg
Biomarkers in exhaled breath continue to be intriguing targets for detecting and monitoring of a variety of health conditions. Due to their low concentrations and the difficulty of*developing sensors, there’s still a lot of untapped potential for breath analysis. To speed this process along,*researchers at Fujitsu have developed a sensor that can accurately measure ammonia in exhaled breath, down to 10 parts per billion, *a marker that can point to signs of liver disease and the ulcer-causing H. pylori*bacterial*infection. Additionally, the researchers developed a modified device able of*measuring **nanal, a potential biomarker for lung cancer.
The researchers plan on expanding the capability of the sensor platform to detect a lot of other, still **t properly researched, compounds that we exhale.
Here are some details about the tech**logy according to Fujitsu:
Copper ions in copper(I) bromide, a P-type semiconductor, undergo a reversible adsorption with ammonia molecules. Making use of this property, Fujitsu Laboratories developed a sensor in which the film thickness and copper(I) bromide composition were optimized for use as a breath sensor. Because electron supply from the ammonia reduces the carriers in the film, this has the effect of increasing electrical resistance between electrodes. This phe**me**n was used and the reactions quantified. As a result, with a sensitivity differential of 2,500 times that for acetone, a**ther gas commonly found in the breath, the sensor was able to distinguish and measure just ammonia from a level of 10 parts per billion (ppb).
