Science Nation: This Breathalyzer Reveals Signs of Disease

It’s the Single Breath Disease Diagnostics Breathalyzer, and when you blow into it, you get tested for a biomarker. Professor Perena Gouma and her team at Stony Brook University in New York developed a sensor chip that is the “brain” of the breathalyzer. It’s coated with tiny nanowires that look like microscopic spaghetti and are able to detect minute amounts of chemical compounds in the breath.
