ABSTRACT:
The preferred embodiments of the present invention use MRAM technology to detect a shift in the magnetic switching field of a sensor. The shift in the magnetic switching field is caused by the presence of magnetic tagged beads. By measuring the magnitude of the shift in the magnetic field and correlating the magnitude of the shift to the presence of the target molecules, accurate measurements regarding the presence of the target molecules can be made.
