    Abstract: Described are embodiments of an invention for detecting target antigens in a biological sample using a sample assembly. Detection may be accomplished by performing a method comprising: sweeping a head module over the sample assembly, wherein said head module includes at least one magneto-resistive read sensor configured to detect target antigens via nanoparticles within the sample assembly; and detecting at least one particular antigen among the target antigens. Preferably, detecting the target antigens via the nanoparticles is based at least in part on detecting unique magnetic properties of particular nanoparticles specifically associated with different types of the target antigens. Detection using a magnetic read/write head in the sample assembly facilitates automation of sample detection with high speed and fidelity. Corresponding systems are also disclosed.

    Abstract: A method of forming a sample assembly of a biological sample having target antigens comprises: forming at least one sample trench within an outer layer, the sample trench having a bottom surface; forming a base layer; bonding a first set of antibodies within the sample trench on a first surface of the base layer; exposing the sample trench with the first set of bonded antibodies to the biological sample having target antigens, the target antigens bonding with the first set of antibodies within the sample trench; bonding a second set of antibodies to nanoparticles, the first and second sets of antibodies being biologically identical; and exposing the target antigens within the sample trench to the second set of antibodies bonded to the nanoparticles, the second set of antibodies bonding with the target antigens within the sample trench.
