The functioning of devices comprising low-dimensional structures as basic elements depends on quantum effects, which play a crucial role in the unique properties of nanomaterials
point contacts as the basic element of quantumsensor devices [3][4].
Of all modern nanosensors measuring a variation in electrical conductance, point-contact sensors have a number of unique properties. The nontrivial nature of point-contact sensors is based on the distinctive properties of the Yanson
mathematical models for obtaining the dependence of the concentration of the target substance on the output signal parameters of a quantumsensor yields an effective calibration function for a noninvasive analysis of the serotonin and cortisol levels in the human body using the breath test.
