Abstract: An apparatus, method and computer-readable medium configured to transport a constituent of fluid sample that binds to a functionalized magnetic particle. The apparatus includes a substrate connected to an input port, a magnetic nanowire, and either a temporally changing magnetic field generator or a spin-polarized current source. The magnetic nanowire is disposed in a surface of the substrate. The width and thickness of the magnetic nanowire are configured so that a domain wall propagating along the nanowire in response to the temporally changing magnetic field continuously couples to a superparamagnetic particle introduced into the input port.

Abstract: A thin-film device for detecting the variation of intensity of physical quantities, in particular a magnetic field, in a continuous way, comprises an electrical circuit including one or more sensitive elements, which are designed to vary their own electrical resistance as a function of the intensity of a physical quantity to be detected. One or more of the sensitive elements comprise at least one nanoconstriction, and the nanoconstriction comprises at least two pads made of magnetic material, associated to which are respective magnetizations oriented in directions substantially opposite to one another and connected through a nanochannel. The nanochannel is able to set up a domain wall that determines the electrical resistance of the nanoconstriction as a function of the position, with respect to the nanochannel, of the domain wall formed in the sensor device. At least one cross section of the nanochannel is configured so as to present a variable extension along one or more axes as a function of different values of the physical quantity to be detected.

Abstract: An apparatus is provided for quantitatively measuring combinations of magnetic particles combined with analytes whose amount or other characteristic quality is to be determined. The magnetic particles are complexed with the analytes to be determined and are excited in a magnetic field. The magnetizations of the magnetic particles are thereby caused to oscillate at the excitation frequency in the manner of a dipole to create their own fields. These fields are inductively coupled to at least one sensor such as sensing coils fabricated in a gradiometer configuration. The output signals from the sensing coils are appropriately amplified and processed to provide useful output indications.

Abstract: Quantum computing systems and methods that use opposite magnetic moment states read the state of a qubit by applying current through the qubit and measuring a Hall effect voltage across the width of the current. For reading, the qubit is grounded to freeze the magnetic moment state, and the applied current is limited to pulses incapable of flipping the magnetic moment. Measurement of the Hall effect voltage can be achieved with an electrode system that is capacitively coupled to the qubit. An insulator or tunnel barrier isolates the electrode system from the qubit during quantum computing. The electrode system can include a pair of electrodes for each qubit. A readout control system uses a voltmeter or other measurement device that connects to the electrode system, a current source, and grounding circuits. For a multi-qubit system, selection logic can select which qubit or qubits are read.

Abstract: Assay methods utilizing the response of a magnetically responsive reagent to the influence of a magnetic field to qualitatively or quantitatively measure binding between specific binding pair members. According to the invention, the presence of an analyte mediates whether or not the magnetically responsive reagent binds to a mobile solid phase reagent. The extent of binding will modulate the response of the magnetically responsive reagent or that of the mobile solid phase reagent, or both, to the influence of a magnetic field. Hence, by measuring the response to the magnetic field of the magnetically responsive reagent, or that of the mobile solid phase reagent, the presence or amount of analyte contained in a test sample can accurately be determined. The invention utilizes various devices to carry out the assay methods described.

Abstract: Magnetite particles suitable for injection into the blood stream of patients having enhanced resistance against agglomeration and uptake by the RES of the liver and spleen. The particles essentially consist of an iron oxide core and a phosphoric acid mono alkyl or alkenyl ester or glycerophospholipid/surfactant three dimensional shell surrounding the core. The core and the monoester or a micellar glycerophospholipid form an urchin-like structure which is further interlaced or intertwined with a non-ionic surfactant to produce a protective three dimensional shell which renders particles almost undetectable by the macrophages. Particles prepared according to the invention are kept in the blood circulation for long periods and represent excellent long lasting blood pool agents. Key components in the shell are (a) a polybasic mineral-organic species such as glycero phosphatidic acid in micellar form and (b) a block copolymer having successive hydrophilic and hydrophobic segments.

Abstract: The invention provides porous particles that produce a predetermined optical response and that may be manipulated magnetically. A preferred particle of the invention has a porous structure that produces a predetermined optical response and magnetic material adhered to the particle. Another preferred particle is amphiphilic. The optical response provided by a particle of the invention enables particles of the invention to be used in sensing, labeling, signaling, display and many other applications. The magnetic nature of the present magnetic particles permits the particles themselves to be manipulated, e.g., vibrated, moved and re-oriented. The porous particles can also be used to control, move, and/or deliver small volumes of liquids and solids associated with the particles.

Abstract: The present invention provides methods for isolating a defined quantity of DNA target material from other substances in a medium. The method may be carried out using a known quantity of a silica-containing solid support, such as silica magnetic particles, having a definable capacity for reversibly binding DNA target material, and DNA target material in excess of the binding capacity of the particles. The methods of the present invention involve forming a complex of the silica magnetic particles and the DNA target material in a mixture of the medium and particles, and separating the complex from the mixture using external magnetic force. The DNA target material may then be eluted from the complex. The quantity of DNA target material eluted may be determined based on a calibration model. The methods of the present invention permit isolation of DNA target material which is within a known quantity range. The methods of the invention eliminate the step of quantitating purified biological samples prior to further processing, such as amplification, Short Tandem Repeat (STR) analysis, and DNA sequencing. Samples of the DNA target materials may be obtained from liquid or solid media, such as liquid blood or paper.
