Patent number: 10914800Abstract: Technologies relating to a magnetic resonance spectrometer are disclosed. The magnetic resonance spectrometer may include a doped nanostructured crystal. By nanostructuring the surface of the crystal, the sensor-sample contact area of the crystal can be increased. As a result of the increased sensor-sample contact area, the output fluorescence signal emitted from the crystal is also increased, with corresponding reductions in measurement acquisition time and requisite sample volumes.Type: GrantFiled: July 11, 2016Date of Patent: February 9, 2021Assignee: STC.UNMInventors: Victor Acosta, Andrejs Jarmola, Lykourgos Bougas, Dmitry Budker

Patent number: 8587304Abstract: An optical atomic magnetometers is provided operating on the principles of nonlinear magneto-optical rotation.

Patent number: 8570035Abstract: A novel approach to magnetic resonance imaging is disclosed. Blood flowing through a living system is prepolarized, and then encoded. The polarization can be achieved using permanent or superconducting magnets. The polarization may be carried out upstream of the region to be encoded or at the place of encoding. In the case of an MRI of a brain, polarization of flowing blood can be effected by placing a magnet over a section of the body such as the heart upstream of the head. Alternatively, polarization and encoding can be effected at the same location. Detection occurs at a remote location, using a separate detection device such as an optical atomic magnetometer, or an inductive Faraday coil. The detector may be placed on the surface of the skin next to a blood vessel such as a jugular vein carrying blood away from the encoded region.Type: GrantFiled: December 12, 2008Date of Patent: October 29, 2013Assignee: The Regents of the University of CaliforniaInventors: David Wemmer, Alexander Pines, Louis Bouchard, Shoujun Xu, Elad Harel, Dmitry Budker, Thomas Lowery, Micah Ledbetter

Patent number: 8547095Abstract: A method and apparatus are described wherein a micro sample of a fluidic material may be assayed without sample contamination using NMR techniques, in combination with magnetoresistive sensors. The fluidic material to be assayed is first subject to pre-polarization, in one embodiment, by passage through a magnetic field. The magnetization of the fluidic material is then subject to an encoding process, in one embodiment an rf-induced inversion by passage through an adiabatic fast-passage module. Thereafter, the changes in magnetization are detected by a pair of solid-state magnetoresistive sensors arranged in gradiometer mode. Miniaturization is afforded by the close spacing of the various modules.Type: GrantFiled: April 2, 2010Date of Patent: October 1, 2013Assignee: The Regents of the University of CaliforniaInventors: Dmitry Budker, Alexander Pines, Shoujun Xu, Christian Hilty, Micah P.

Publication number: 20120112749Abstract: An atomic vapor cell apparatus and method for obtaining spin polarized vapor of alkali atoms with relaxation times in excess of one minute is provided. The interior wall of the vapor cell is coated with an alkene-based material. The preferred coatings are alkenes ranging from C18 to C30 and C20-C24 are particularly preferred. These alkene coating materials, can support approximately 1,000,000 alkali-wall collisions before depolarizing an alkali atom, an improvement by roughly a factor of 100 over traditional alkane-based coatings. Further, the method involves a combination of one or more of the following: the use of a locking device to isolate the atoms in the volume of the vapor cell from the sidearm used as a reservoir for the alkali metal vapor source, careful management of magnetic-field gradients, and the use of the spin-exchange-relaxation-free (SERF) technique for suppressing spin-exchange relaxation.Type: ApplicationFiled: November 1, 2011Publication date: May 10, 2012Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Dmitry Budker, Micah Ledbetter, Todor Karaulanov, Mikhail V.

Patent number: 7994783Abstract: An integral microfluidic device includes an alkali vapor cell and microfluidic channel, which can be used to detect magnetism for nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). Small magnetic fields in the vicinity of the vapor cell can be measured by optically polarizing and probing the spin precession in the small magnetic field. This can then be used to detect the magnetic field of in encoded analyte in the adjacent microfluidic channel. The magnetism in the microfluidic channel can be modulated by applying an appropriate series of radio or audio frequency pulses upstream from the microfluidic chip (the remote detection modality) to yield a sensitive means of detecting NMR and MRI.Type: GrantFiled: February 6, 2009Date of Patent: August 9, 2011Assignee: The Regents of the Univerisity of CaliforniaInventors: Micah P.

Patent number: 7573264Abstract: A laser-based atomic magnetometer (LBAM) apparatus measures magnetic fields, comprising: a plurality of polarization detector cells to detect magnetic fields; a laser source optically coupled to the polarization detector cells; and a signal detector that measures the laser source after being coupled to the polarization detector cells, which may be alkali cells.

There is no need of a magnetic field or cryogenics in the detection step, as it is detected through the LBAM.Type: GrantFiled: November 27, 2006Date of Patent: August 11, 2009Assignee: The Regents of the University of CaliforniaInventors: Shoujun Xu, Thomas L.
