  • Patent number: 11261473
    Abstract: A method and an apparatus are described for the generation of microparticles containing an immobilized functional component, where the following measures are proposed: spraying a liquid (32) containing a soluble alginate and a functional component consisting of molecules or nanoparticles to generate a stream (60) of droplets, directing the stream (60) of droplets onto a precipitation bath (16) and capturing the droplets therein by application of high voltage (14), precipitating the droplets in the precipitation bath (16) via a precipitation liquid (18) containing an alginate complexing agent, such that the droplets are solidified to form microparticles (10) containing the functional component and extracting the microparticles (10) from the precipitation bath (16).

  • Patent number: 8814808
    Abstract: Body fluid sampling device comprising a skin-piercing element having a collection zone for receiving body fluid. In one embodiment, the collection zone includes a plurality of holes, e.g., 3 or more holes, or 50 to 100 holes. The hole size may be small, e.g., having a diameter of 0.01 to 0.5 mm. The holes may or may not extend through the lancet. In some embodiments, the holes have a depth of 50 to 500 ?m. In other embodiments, the collection zone is porous, or is a roughened area. The collection zone can take up a very small volume of body fluid, e.g., 3 to 10 nL, in a very short time period, e.g., less than 0.5 seconds. In other embodiments, the device further comprises a fluid receiving means spaced apart from the collection zone so that body fluid in the collection zone will not contact the fluid receiving means initially.

  • Patent number: 8404478
    Abstract: A diagnostic test tape for liquid samples is provided comprising a flexible transport tape and a plurality of test fields applied to the transport tape that are distributed in the longitudinal direction of the tape, where said test fields comprise a detection layer and a spreading net spanning the detection layer for a planar uptake of liquid sample, wherein the spreading net is formed from a lattice-like fabric comprising fabric threads that cross at right angles. In order to prevent the fabric from arching up under tape tension it is proposed that the fabric is oriented obliquely to the transport tape such that all fabric threads run obliquely to the longitudinal direction of the tape.
