Scientists have developed experimental breath analyzers, but most of these devices only focused on a single type of disease, such as cancer. Researchers from the Israel Institute of Technology have created a device that can identify 17 different diseases, including lung cancer or Parkinson's disease. The researchers developed an array of nanoscale sensors to detect the components in breath samples from more than 1,400 patients who were either healthy or had one of 17 different diseases, such as kidney cancer, Parkinson's disease, pulmonary hypertension and other diseases. Each sample was then passed through the breathalyzer, which could detect the types of chemicals and in what quantities. As the researchers report in the journal ACS Nano, the data from the breathalyzer could detect if a person is suffering from diseases almost nine out of ten times.
