Claim 0:
1. A system comprising:
an apparatus comprising:
at least one permanent magnet; and
at least one magnetic field sensor at a pole of the at least one permanent magnet and configured to be positioned relative to a surface of a membrane containing immobilized magnetic particles selectively bound to an analyte such that the magnetic particles are magnetized by the at least one permanent magnet;

a stage mechanically coupled to at least one of the apparatus and the membrane, the stage configured to move at least one of the apparatus and the membrane relative to one another with an oscillatory movement along a first direction parallel to the surface of the membrane;
at least one controller configured to control the oscillatory movement of the stage and to generate first synchronization trigger signals indicative of the oscillatory movement; and
a data acquisition unit configured to receive sensor signals from the at least one magnetic field sensor and the first synchronization trigger signals from the at least one controller.
