Researchers Develop Compact Breathalyzer That Detects the Flu
Researchers at the University of Texas at Arlington have created a prototype breathalyzer-style device capable of detecting the influenza virus in its early stages -- before you start to show symptoms. "What I have created -- together with my research team and research collaborators working on this project -- is a single exhale, portable, handheld, potentially wireless, battery-operated, inexpensive, breathalyzer that relies on gas-selective sensing elements, and which detects the presence and monitors the concentration of biomarkers in breath that signal a disease," Perena Gouma, a professor in the university's Materials Science and Engineering Department, told Digital Trends. From the report: The specific biomarkers the breathalyzer looks for include traces of nitric oxide and ammonia, both of which can be measured using smart sensors. "This particular breathalyzer detects flu virus infection," she continued. "This is expected to be a personalized diagnostics tool available over the counter and it will allow the individuals to monitor their health, with the option of sharing the data obtained with their physician in real time." Gouma has previously developed other breathalyzers, for everything from asthma detection and diabetes monitoring to determining an endpoint for hemodialysis, the process of filtering waste products from the blood. The neat thing about breathalyzers, Gouma said, is that the technology involved can be easily modified to detect different diseases simply by changing the sensors. In this example, for instance, it could be upgraded to instead test for Ebola. As for when this technology may be available, Gouma said the team needs to carry out clinical trials, "but we are already exploring our options for commercializing this tool."Read more of this story at Slashdot.
