The goal of this book is to provide an introduction to the practical use of mobile NMR at a level as basic as the operation of a smart phone. Each description follows the same didactic pattern: introduction, basic theory, pulse sequences and parameters, beginners-level measurements, advanced-level measurements, and data processing. Nuclear Magnetic Resonance (NMR) spectroscopy is the most popular method for chemists to analyze molecular structures while Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic tool for medical doctors that provides high-contrast images of biological tissue depicting the brain function and the beating heart. In both applications large super-conducting magnets are employed which magnetize atomic nuclei of an object positioned inside the magnet. Their circulating motion is interrogated by radio-frequency waves. Depending on the operating mode, the frequency spectrum provides the chemist with molecular information, the medical doctor with anatomic images, while the materials scientist is interested in NMR relaxation parameters, which scale with material properties and determine the contrast in magnetic resonance images. Recent advances in magnet technology led to a variety of small permanent magnets, by which NMR spectra, images, and relaxation parameters can be measured with mobile and low-cost instruments.

Essential NMR gives scientists and engineers an easy and quick refresher on their NMR knowledge and skills. At the same time, this primer and review affords lecturers material to provide a deliver a framework of basic know-how covering all fields of NMR, i.e. NMR methodology and hardware, chemical analysis, 2D-spectroscopy, NMR imaging, flow NMR, and quality-control NMR. Concise explanatory text, with the key information, is enhanced a color illustration that graphically reinforces understanding. Rigorous derivations are avoided in favor of intuitive arguments. No other teaching-and-learning text addresses all the different aspects of NMR in such a comprehensive and concise fashion.

A Compact Orthogonal Field Sensor for emitting two orthogonal electro-magnetic fields in a common space. More particularly, a replacement inductor for existing NMR (Nuclear Magnetic Resonance) sensors to allow for NMR imaging. The Compact Orthogonal Field Sensor has a conductive coil and a central conductor electrically connected in series. The central conductor is at least partially surrounded by the coil. The coil and central conductor are electrically or electro-magnetically connected to a device having a means for producing or inducing a current through the coil and central conductor. The Compact Orthogonal Field Sensor can be used in NMR imaging applications to determine the position and the associated NMR spectrum of a sample within the electro-magnetic field of the central conductor.

Metabolic syndrome (MetS) is a cluster of metabolic abnormalities. The designation of MetS requires three or more of five clinical criteria: central obesity, high triglycerides, low HDL cholesterol, elevated blood pressure and high blood glucose. The main purpose of the MetS diagnosis is to prevent diabetes. However, the clinical criteria of MetS are poorly calibrated and fail to detect early metabolic abnormalities essential for diabetes prevention. Additionally, the MetS definition lacks a measure of chronic inflammation, an important driver of metabolic dysregulation. Our lab has shown that plasma and serum water T2, measured using benchtop nuclear magnetic resonance (NMR) relaxometry, are better metabolic health indicators and inclusive of inflammation. In Chapter 2 of this dissertation, we describe a broad-based, unbiased proteomic search for new biomarkers that predict plasma and serum water T2. Using a multistep statistical approach, we identified five circulatory proteins that are strongly implicated in metabolic health. In Chapter 3, we investigated whether whole blood T2 can provide similar metabolic information. Mixed blood yielded a single T2, whereas settled blood gave rise to two distinct T2 values for the cell pellet (T2P) and plasma supernatant (T2S). Supernatant T2S showed strong correlations with red blood cell count and hematocrit, and this association was due to paramagnetic relaxation enhancement. In contrast, the pellet T2P exhibited strong correlations with metabolic biomarkers. Hemoglobin glycation (HbA1C, a marker of metabolic health) is responsible for this association, as it provides water binding sites that lead to faster T2 relaxation because of increased binding and chemical exchange. The T2 value for mixed blood revealed strong associations with red blood cell count and hemoglobin. In Chapter 4, we investigated the feasibility of acquiring T2 data non-invasively from living human tissue using a custom-build NMR relaxometry device equipped with a magnet configuration to accommodate the human fingertip. Using healthy volunteers, we showed that three T2 components, corresponding primarily to different mobility domains of adipose tissue, can be measured reproducibly, with significant subject-to-subject biological variation. We propose that the source of variation is adipose tissue fluidity, which varies with lipid composition and the state of connective tissue matrix.
