86% accuracy was achieved with the artificially intelligent nanoarray hreathalyzer for detection and discrimination of 17 disease conditions examined.
Before modern medical lab techniques became available, doctors diagnosed some diseases by smelling a patient’s breath. Scientists have been working for years to develop analytical instruments that can mimic this sniff-and-diagnose ability. Now, researchers report in the journal ACS Nano that they have identified a unique “breathprint” for each disease. Using this information, they have designed a device that screens breath samples to classify and diagnose several types of diseases.
Exhaled breath contains nitrogen, carbon dioxide and oxygen, as well as a small amount of more than 100 other volatile chemical components...
