A researcher collaboration between scientists at University of Colorado–Denver and Technion–Israel Institute of Technology has successfully tested a gold nanoparticle (GNP)-based sensor that can detect lung cancer (LC) markers in a patient’s breath. The technology, which we’ve been following at Medgadget for a few years now (see flashbacks below), is able to rapidly identify small molecule volatile organic compounds that might point to the presence of lung cancer.
The team compared the sensor to gas chromatography–mass spectrometry identification finding that the new device provided “significant discrimination between (i) LC and healthy states; (ii) small cell LC and non–small cell LC; and between (iii) two subtypes of non–small cell LC: adenocarcinoma and squamous cell carcinoma.”
The researchers believe the new technology will not only help with diagnosing LC, but with monitoring how specific treatments are benefiting the patient.
