A Hand-Held, Single-Sided NMR Sensor for Full-Thickness Skin Detection
IEEE Sensors Journal, 2023To rapidly assess burn depth, a hand-held, single-sided nuclear magnetic resonance (NMR) sensor was designed for full-thickness skin detection. The sensor is composed of a single-sided magnet, a radio frequency coil, a matching circuit, and an aluminum ...

A Portable Halbach NMR Sensor for Detecting the Moisture Content of Soybeans
IEEE Transactions on Instrumentation and Measurement, 2022We report a low-field (160 mT) and lightweight (2.45 kg) Halbach nuclear magnetic resonance (NMR) sensor for non-destructive measurement of soybean moisture content (MC) on site.

Small NMR biomolecular sensors
Solid-State Electronics, 2013Abstract By combining the physics of nuclear magnetic resonance (NMR) and silicon radio-frequency (RF) integrated circuits, we recently created progressively smaller NMR systems, which we originally reported in Refs. [1] , [2] , [3] , [4] . Our strategy for NMR system miniaturization proved effective, culminating in the smallest prototype [3] ,

Motional relativity and industrial NMR sensors
Journal of Magnetic Resonance, 2006We explore the implications of motional relativity in NMR and show that sample translation can be used to acquire NMR signals without the need for pulsed RF excitation or pulsed magnetic field gradients. Novel single-shot, on-line NMR acquisition protocols for samples being conveyed at high speed are discussed and preliminary results using a low-cost ...

Molecular Sensors for NMR-Based Detection
Chemical Reviews, 2018Reliable and precise methods capable of unambiguously identifying target analytes in real-world samples are indispensable in various fields, ranging from biological studies and diagnosis to quality control. Among various analytic techniques, nuclear magnetic resonance (NMR) is uniquely powerful as it provides multidimensional data useful for structural

Broadband and multi-resonant sensors for NMR
Progress in Nuclear Magnetic Resonance Spectroscopy, 2019It has always been of considerable interest to study the nuclear magnetic resonance response of multiple nuclei simultaneously, whether these signals arise from internuclear couplings within the same molecule, or from uncoupled nuclei within sample mixtures.

A mobile one-sided NMR sensor with a homogeneous magnetic field: the NMR-MOLE.
Journal of Magnetic Resonance, 2006A new portable NMR sensor with a novel one-sided access magnet design, termed NMR-MOLE (MObile Lateral Explorer), has been characterised in terms of sensitivity and depth penetration. The magnet has been designed to be portable and create a volume with a relatively homogeneous magnetic field, 15,000 ppm over a region from 4 to 16 mm away from the probe,

NMR With Superconducting-GMR Mixed Sensors
IEEE Transactions on Applied Superconductivity, 2009We have developed a very sensitive field sensor to detect magnetic signals in the femtotesla range. This mixed sensor is based on the association of a superconducting flux-to-field transformer with a magnetoresistive field sensor. The bandwidth of a GMR being wide and only limited in the GHz regime, where the ferromagnetic resonance of the free layer ...
