Disclosed is a device for non-invasively sampling interstitial fluid including one or more analytes from dermis to the skin surface by employing the magneto-hydrodynamic effect and/or reverse iontophoresis. According to a preferable embodiment the device includes a first frame including a first electrode and a second frame including a second electrode, power source and preferably also a first magnet. The first frame is connected to the second frame by a formable connector adapted to provide mechanical connection between the first frame and the second frame and electrical connection between the power source and the first electrode. The direction of the magnetic field and the direction of the electric current produced by the magnet and the power source is such that the Lorenz force drives the fluid from the dermis towards the skin surface.

Device for sampling one or more analytes

The present invention relates to a device exploiting magneto-hydrodynamics (MHD) for localized delivery of material into a target or extraction of material from a target. The device includes a frame () comprising a space () for conductive fluid and the material, at least one pair of electrodes (A,B) facing each other, a source of electric current (), a magnet (), and an opening (). The electric current and the magnetic field are synchronized so that the material can be moved from the volume between the electrodes through the opening towards the target or from the target through the opening towards the volume. According to the invention the volume is &#x2264;2000 mm, in proviso that mean distance between tips of the electrodes is &#x2264;20 mm.

Device and method for localized delivery and extraction of material

The application relates to a device () for non-invasively sampling interstitial fluid comprising one or more analytes from dermis () to skin surface () by using the magneto-hydrodynamic effect. The device comprises a first electrode () and a second electrode () adapted to be positioned adjacent to the skin surface, the first electrode separated from the second electrode by a distance (), a power source () adapted to induce an electric current through the first electrode, the interstitial fluid and the second electrode, and also a magnet () adapted to produce a magnetic field to the interstitial fluid. Direction of the magnetic field and direction of the electric current produced by the magnet and the power source, respectively, is such that Lorentz force drives the fluid from the dermis towards the skin surface.
