摘要： A biosensor includes a magnetic structure having grooved surface to biologically bond magnetic labels to a biological substance within the grooves. The grooves are positioned within the magnetic structure so that stray magnetic fields from the magnetic structure magnetize magnetic labels within the groove. The magnetic labels 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.
