| The present invention relates to a zinc-containing magnetic nanoparticle-based magnetic separation system or magnetic sensor comprising a zinc-containing magnetic nanoparticle (preferably, a zinc-containing magnetic nanoparticle of which a binding agent having a binding affinity to a target material or analyte is bound on the surface) or a cluster thereof. Since the zinc-containing magnetic nanoparticles used in this invention have very high saturation magnetism, the present magnetic separation system using the same has much more improved separation efficiencies. Due to higher saturation magnetism of the zinc-containing magnetic nanoparticle used in this invention, the present magnetic sensor using the same may also detect analytes in a much more sensitive manner. The nanoparticles having improved sensitivity (e.g., sensitivity in fM level) prepared by the present invention may permit to detect a trace amount of analytes such as anti-cancer marker proteins or nucleic acid molecules, and prion proteins in blood. | ||||||

| Inductive sensors measure the near surface properties of conducting and magnetic material. A sensor may have primary windings with parallel extended winding segments to impose a spatially periodic magnetic field in a test material. Those extended portions may be formed by adjacent portions of individual drive coils. Sensing elements provided every other half wavelength may be connected together in series while the sensing elements in adjacent half wavelengths are spatially offset. Certain sensors include circular segments which create a circularly symmetric magnetic field that is periodic in the radial direction. Such sensors are particularly adapted to surround fasteners to detect cracks and can be mounted beneath a fastener head. In another sensor, sensing windings are offset along the length of parallel winding segments to provide material measurements over different locations when the circuit is scanned over the test material. The distance from the sensing elements to the ends of the primary winding may be kept constant as the offset space in between sensing elements is varied. An image of the material properties can be provided as the sensor is scanned across the material. | ||||||

| In general, the present disclosure is directed toward a novel hybrid spintronic device for converting chemical absorption into a change in magnetoresistance. This device uses a novel magnetic material which depends on the attachment of an organic structure to a metallic film for its magnetism. Changes in the chemical environment lead to absorption on the surface of this organometallic bilayer and thus modify its magnetic properties. The change in magnetic properties, in turn, leads to a change in the resistance of a magnetoresistive structure or a spin transistor structure, allowing a standard electrical detection of the chemical change in the sensor surface. | ||||||
| 137 | METHOD AND APPARATUS FOR MEASURING MATERIAL PROPERTIES AND LIFT-OFF COMPONENTS OF AN OBJECT USING A MAGNETIC PROBE | PCT/GB0204531 | 2002-10-07 | WO03034054A3 | 2003-09-12 | BUTTLE DAVID JOHN |
| Method and apparatus for measuring material properties such as stress in a ferromagnetic material using an electromagnetic probe. While generating an alternating magnetic field in the object, and sensing the resulting magnetic field with a sensor, the signals from the magnetic sensor may be resolved into in-phase and guadrature components. The signals are affected by both geomaterical parameters such as lift-off any by material properties, but these influences may be separated by mapping the in-phase and quadrature components directly into material property and lift-off components, and hence a material property and/or the lift-off may be determined. The mapping may be represented in the impedance plane as two sets of contours representing signal variation with lift-off (A) (for different values of stress) and signal variation with stress (B) (for different values of lift-off), the contours of both sets (A, B) being curved. The stress contours (B) at a constant angle. Hence calibration measurements taken along a few contours of each set enable the positions of the other contours of each set to be determined. | ||||||
