MIT engineers designed a portable, chip-scale sensor named PlasmoSniff that detects disease-related biomarkers exhaled by patients after inhaling nanoparticles tagged with synthetic biomarkers. These nanoparticles release biomarkers only when acted upon by enzymes specific to infections like pneumonia, enabling disease detection through breath analysis.
Unlike traditional lab-based methods needing bulky instruments, PlasmoSniff identifies these exhaled biomarkers at very low concentrations. The technology aims for a handheld device that could provide clinical or at-home pneumonia diagnostics within minutes, significantly reducing dependence on chest X-rays or slow lab results.
