A recent study involved researchers testing the breath samples from over 1,400 patients in order to determine if they were suffering from cancer, Parkinson’s disease, Crohn’s disease, pulmonary hypertension or other diseases. This is a revolutionary breakthrough for the medical field ad will not only work in the diagnosing of cancer, but in 16 other different diseases as well.
Each ailment has a signature fingerprint that reveals its individual composition of organic compounds. “These odor signatures are what enables us to identify the diseases using the technology that we developed,” says Prof. Hossam Haick, leader of the research project. The project involved the team building an “artificially intelligent nanoarray”, which they decided to call the Na-Nose. This was able to pick up the presence and ratio of various chemicals using specific sensors made from nanoparticles and others that utilizes nanotubes to detect different compounds.
One data has been gathered from the breath test it’s then analyzed by an AI system which produces a result that’s got an 86 percent success rate. But, that’s not quite a high enough accuracy rate for it to be adopted for clinical use just yet. However it could one day be used as a routine test for the early detection of various diseases, making them much easier to treat. Haick said, “For example, in the case of lung cancer we can increase the survival rate from 10 to 70 percent by early diagnosis. It is available without the need for invasive and unpleasant procedures, it’s not dangerous, and you can sample it again and again if necessary.”
