Noninvasive real-time breath test for controlling hormonal background of the human body: detection of serotonin and melatonin with quantum point-contact sensors
Significant progress in development of noninvasive diagnostic tools based on breath analysis can be
expected if one employs a real-time detection method based on finding a spectral breath profile
which would contain some energy characteristics of the analyzed gas mixture. Using the fundamental
energy parameters of a quantum system, it is possible to determine with a high accuracy its
quantitative and qualitative composition. Among the most efficient tools to measure energy
characteristics of quantum systems are sensors based on Yanson point contacts. This paper reports
the results of serotonin and melatonin detection as an example of testing the human hormonal
background with point-contact sensors, which have already demonstrated their high efficiency in
detecting carcinogenic strains of Helicobacter pylori and selective detection of complex gas
mixtures. When comparing the values of serotonin and melatonin with the characteristic parameters of
the spectral profile of the...
