Abstract:
1. A magnetic nanoparticle presence detecting sensor, comprising: a support; a sensor body arranged on the support and including a planar ferromagnetic nanostructure having a detection area shaped as a strip bent to form a corner, the sensor body being structured to apply a magnetic field to cause the detection area to selectively assume, in response to the applied magnetic field: a plurality of non-magnetic contacts arranged on the support and electrically conductively connected to the sensor body; and a measuring device which measures a magnetoresistance, the device arranged on the sensor and connected to the plurality of non-magnetic contacts, the measuring device being structured to provide a measure of the transition threshold by way of measures of the magneto-resistance of the detection area in the first spin configuration and the second spin configuration assumed upon application of the magnetic field.
