More Information
Summary: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.
