Stable breathprints unique to each person may have diagnostic applications. This is according to an article published in the open access journal PLOS ONE by a research team supported by a Marie Curie European Reintegration Grant Choose translations of the previous link .

According to the article, there is an essential "breathprint" unique to each person that is very specific and might be related to its owner. Even though the factors are still unknown, diet, health conditions or exposure to other chemicals seem to be some of the causes of the breathprint. The research is coordinated by the Eidgenössische Technische Hochschule Zürich and supported by 45.000 euros in the frame of the "Cancer metabolic profiling through ion mobility and mass spectrometric-based methods" project.
