Magnetic Computer Sensors May Help Study Biomolecules (image) National Institute of Standards and Technology (NIST) Share Print E-Mail Caption This still from a video micrograph shows a strand of magnetic particles trapped by a "spin valve" -- which is highlighted in white -- and rotated by the application of an external rotating magnetic field. NIST is studying the possible use of spin valves arrays for parallel processing of biological molecules.
