Ultrasensitive nanoscale sensors can identify lung cancer through exhaled isoprene

Exhaled breath contains chemical clues to what's going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses—and improve patients' prospects. In a study in ACS Sensors, researchers report developing ultrasensitive nanoscale sensors that in small-scale tests distinguished a key change in the chemistry of the breath of people with lung cancer. November is Lung Cancer Awareness Month.
