This Breathalyzer Reveals Signs of Disease – Science Nation

This invention could give new meaning to the term “bad breath!” It’s the Single Breath Disease Diagnostics Breathalyzer, and when you blow into it, you get tested for a biomarker—a sign of disease. For as amazing as that sounds, the process is actually very simple thanks to ceramics nanotechnology. All it takes is a single exhale. With support from the National Science Foundation (NSF), Professor Perena Gouma and her team at Stony Brook University in New York developed a sensor chip that you might say 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…
