New Device Uses Gold Nanoparticles to Test for Lung Cancer, University of Colorado Study

The metabolism of lung cancer patients is different than the metabolism of healthy people. And so the molecules that make up cancer patients' exhaled breath are different too. A new device pioneered at the University of Colorado Cancer Center and Nobel-Prize-winning Technion University in Haifa, Israel uses gold nanoparticles to trap and define these molecules in exhaled breath. By comparing these molecular signatures to control groups, the device can tell not only if a lung is cancerous, but if the cancer is small-cell or non-small-cell, and adenocarcinoma or squamous cell carcinoma.
