Abstract: The invention relates to a device for contactless control of magnetic beads on a microfluidic card by means of external magnetic fields, without having to use complicated mechanics or hydraulics. Based on a modulation of the gradient of a magnetic field, magnetic beads are lifted in a first step in a contactless way out of different reaction chambers of the microfluidic card. By means of a translation movement or a variation or modulation of the gradient of a magnetic field, horizontal transport of the magnetic beads over a mechanical barrier of the microfluidic card is facilitated in a second step. It is possible in a third step to use a further modulation of the gradient of the magnetic field to lower the magnetic beads into a desired further fluid zone.

Abstract: The invention relates to a method for the thermal control of at least one temperature-dependent enzymatic reaction in the presence of magnetic particles, particularly nanoparticles, or magnetic beads in vitro by means of the heating of the magnetic beads or magnetic particles to at least one certain target temperature by means of alternating magnetic fields. The enzymatic reaction which can be controlled with the method according to the invention is preferably a PCR reaction or another reaction for the elongation or amplification of nucleic acids, including DNA, RNA or hybrids or derivatives thereof, which takes place directly on the functionalized magnetic beads. Further aspects of the invention relate to a reactor for carrying out the method and the use of the method or the reactor in analytics and diagnostics.
