1. A detection device, comprising:
one or more pole pieces;
at least one magnetic component configured to generate a magnetic field through the one or more pole pieces;
a plurality of sensors, each of the plurality of sensors coupled to at least one of the one or more pole pieces; and
detection circuitry coupled to the plurality of sensors, wherein the detection circuitry is configured to detect a characteristic of each of the plurality of sensors, the characteristic indicating presence or absence of one or more magnetic nanoparticles (MNPs) coupled to at least one of a plurality of molecules to be detected;
and wherein:
at least one of the one or more pole pieces is operable to draw the one or more MNPs toward at least one of the plurality of sensors;
a first subset of the plurality of sensors is arranged in a first row;
a second subset of the plurality of sensors is arranged in a second row, the second row being substantially parallel to the first row; and
at least one reagent area is disposed between the first and second rows.
