Breathalyzer to see if your sniffling chap has man flu: Device uses sensors to detect the virus

A professor at University of Texas Arlington has built a device that when breathed into they are able to detect biomarkers associated with virus infection. The handheld monitor uses semiconductor sensors like those in a carbon monoxide detector. The current standard of practice for flu diagnosis is a nasal swab and using a PCR, which can take up to 30 minutes to complete. This can be cumbersome and uncomfortable. The device combines a nitric oxide and ammonia sensor, which Gouma found to be useful markers in confirming a flu infection. The device only takes seconds to complete and has the potential to catch illnesses early and be used in home settings. The device is more a proof of concept in its current rendition and clinical trials must be performed next in order to confirm the accuracy of the test.
