New express method for melatonin determination in the human body

摘要: Original fundamental properties of Yanson point contacts allow their application to research and technology development at a wide range surrounding conditions. At low temperature these nanoobjects can be used as main instrument point-contact spectroscopy. room they serve sensitive element advanced nanosensors with excellent performance. The most important advantage sensors in investigating complex gas media is the spectral nature response signal. discovery capabilities analysis allows us speak terms multifunctionality expansion possibilities from spectroscopy electron-phonon interaction temperatures gaseous temperatures. Using sensors, this work we propose new non-invasive method for determination melatonin, one hormones characterizing state human body. A series procedures was proposed find melatonin concentration body function sensor action exhaled breath. It has been shown that accurate enough medical purposes real time. results study suggest problem successfully solved by using breath tests based on contacts.
