Abstract
A circuit for detecting antigens on biosample tracks comprising a processor, an electromagnetic write head for magnetizing nanoparticles attached to the antigens via antibodies in response to a write signal from the processor, and a first amplifier for supplying power to the write head. The circuit further comprises a magneto-resistive read sensor for detecting the magnetized nanoparticles upon receiving a read signal from the processor, and a second amplifier for supplying power to the read sensor. The write head and read sensor may be part of a head module in a magnetic tape drive. Nanoparticles of differing magnetic properties may be selectively paired with antibodies associated with different antigens to allow different antigens to be detected upon a single scan by the read-sensor.
