摘要： A magnetic biosensor (100) includes a magnetic structure, such as a GMR spin-valve sensor (10,20,30,40), having grooved surface to biologically bond magnetic labels (50) to a biological substance (80) within the grooves. The grooves (90) are positioned within the magnetic structure so that stray magnetic fields (110) from the magnetic structure magnetize magnetic labels (50) within the groove (90). The magnetic labels (50) may be magnetic nanoparticles or magnetic microbeads. The techniques may reduce or eliminate the usage of any external magnetic field generator, e.g., electromagnets or current lines.

摘要： A system includes a first sensor, a field source, and a processor. The first sensor includes a surface and has an electrical resistance determined by a magnetic field at the surface. The field source is configured to provide a biasing magnetic field to the surface. The biasing magnetic field is aligned parallel to the surface and aligned perpendicular relative to the surface. The magnetic field has a frequency. The processor is coupled to the sensor and is configured to determine a parameter based on a measure of a change in the resistance. The change in the resistance corresponds to the resistance at a time before onset of a magnetic field perturbance at the surface and a time after the onset of the magnetic field perturbance at the surface.
