  • Publication number: 20120276592
    Abstract: A microfluidic system for a polymerase chain reaction is disclosed. The system includes a substrate having three chambers fluidically connected to one another in series, which chambers are held at different temperature levels. An elastic film on the substrate closes the chambers, wherein the chambers connected to one another in series are fluidically closable at the ends of the serial connection. The film above a chamber is movable into the chamber for emptying of the chamber. Thus, without a separate pump, it is possible for a PCR solution to be pumped through the chambers or temperature levels, with the PCR solution in a chamber acquiring the temperature thereof very rapidly.

  • Publication number: 20110306930
    Abstract: A hypodermic needle, particularly for injecting a pharmaceutical substance into a human or animal body is disclosed. The needle provides a simple way of improving long-term use in a human or animal body. The hypodermic needle includes a tubular hollow body having a needle tip for introducing the hypodermic needle into the human or animal body, wherein the hollow body has a rigidity which is reducible by the influence of heat and/or moisture.

  • Publication number: 20110226624
    Abstract: A microfluidic dielectrophoresis system, at least including one supply device for a liquid medium having particles contained therein, N?2 microfluidic, dielectrophoretically active channels, which are equipped with electrodes, lines for the fluidic connection of the supply device to the channels, for the connection of the channels to one another, and for the drainage of the medium and/or the particles from the channels, and valves for setting the flow direction of the medium in the lines, the dielectrophoretically active channels being situated and being connected by lines in such a way that they may be operated connected in parallel and in series by switching the valves in relation to the flow direction of the medium and the electrodes of the various channels are activatable independently of one another. In addition, the present invention relates to the use of a microfluidic dielectrophoresis system according to the present invention and a method for performing a dielectrophoresis.

  • Publication number: 20110139621
    Abstract: A microfluidic cell for the dielectrophoretic separation, accumulation, and/or lysis of polarizable bioparticles, including an interdigital electrode system composed of two electrode groups having interdigitated electrodes, a flat electrode in which the interdigital electrode system and the flat electrode are situated on opposite sides of the cell in order to improve the separation, accumulation and/or lysis characteristics. Moreover, a microfluidic system which includes such a microfluidic cell, and use thereof, and a method for separating, accumulating, and/or lysing polarizable bioparticles is also described.

  • Publication number: 20110139620
    Abstract: A microfluidic cell for the dielectrophoretic separation, accumulation, and/or lysis of polarizable bioparticles, including an interdigital electrode system composed of two electrode groups having interdigitated electrodes, and a micromixer having microchannels and microelevations. The interdigital electrode system and the micromixer are situated on the same side of the cell to improve the separation, accumulation, and/or lysis characteristics. Moreover, also described is a microfluidic system which includes such a microfluidic cell, and use thereof, and a method for separating, accumulating, and/or lysing polarizable bioparticles.
