    摘要： Embodiments of the invention relate to device, method, and system for separation and/or detection of biological cells and biomolecules using micro-channels, magnetic interactions, and magnetic tunnel junctions. The micro-channels can be integrated into a microfluidic device that may be part of an integrated circuit. Magnetic interactions used for the separation are created, in part, by magnetic stripes associated with the micro-channels. Detection of biological cells and biomolecules is effectuated by a magnetic tunnel junction sensor that comprises two ferromagnetic layers separated by a thin insulating layer. The magnetic tunnel junction sensor can be integrated into a silicon based device, such a microfluidic device, an integrated circuit, or a microarray to achieve rapid and specific separation and/or detection of biomolecules and cells.

    摘要： An embodiment of the invention relates to a portable or handheld device for performing NMR analysis. The device comprises a console and a strip which can be placed into the console through a slot or other means. The strip comprises a sample holding place and a microcoil for generating an excitation magnetic field across a sample in the sample holding space. A permanent magnet is provided either by the console or the strip and generates a static magnetic field which, together with the excitation magnetic field, creates NMR within the sample. Other embodiments of the invention also encompass method of performing NMR analysis using the portable device and method of making such devices.
