New Breathalyzer Can Detect Lung Cancer

Israeli scientists have invented a breathalyzer-type device that can detect chemical markers for lung cancer in a patient’s breaths. The sensor relies on a film of gold nanoparticles, which conducts electricity, layered over a carbon-based substrate. When a patient breathes into the device, particulates in the breath accumulate on the carbon layer and the sensor swells [...]
