- A breath test could diagnose pneumonia in minutes
A portable breath test called PlasmoSniff, developed at MIT, could diagnose pneumonia and other lung conditions by detecting biomarkers in exhaled breath. The test uses nanoparticles that release biomarkers in the presence of infection-related enzymes, which are then measured via enhanced Raman spectroscopy. Researchers aim to create a handheld device for clinical or home use.
