Abstract
A method is disclosed for the detection of magnetic particles, so-called beads, immobilized on an essentially flat-planar holding area of a substrate. In at least one embodiment, a sensor array, which is arranged in the holding area and is composed of XMR sensors, is subjected to an external magnetic field and the change in the resistance of an XMR sensor caused by a stray field of a bead is measured to detect the bead, with the external field being produced by passing a direct current through a conductor track which is arranged on the holding area.
