FIELD: electrical equipment.
SUBSTANCE: invention relates to device (100), intended for non-invasive extraction of specimens of interstitial fluid medium containing one or more analytes, from derma (101a) to skin surface (101b) using magnetohydrodynamic effect. This device comprises: first electrode (102a) and second electrode (102b), made with possibility of positioning with adjacency to skin surface and located at distance (103) from each other; power source (104), configured to generate electric current passing through first electrode, interstitial fluid medium and second electrode; as well as magnet (105), configured to generate a magnetic field acting on the interstitial fluid medium, wherein the direction of the magnetic field generated by the magnet, and direction of electric current generated by power supply are selected so that Lorentz force created by them moves fluid from derma in direction of skin surface.
EFFECT: disclosed is a device for selective sampling of one or more analytes.
