Abstract
A biomolecular sensor system includes an array of magnetoresistive nanosensors designed for sensing biomolecule-conjugated superparamagnetic nanoparticles. Materials and geometry of each sensor element are designed for optimized sensitivity. The system includes magnetic field generators to apply forces to superparamagnetic nanoparticles for 1) nanoparticle manipulation, 2) sensor magnetic biasing, 3) magnetic pull-off measurement for differentiation against non-specific association, and 4) removal of all particles from the sensor array surface.
