The drive to improve the sensitivity of nuclear magnetic resonance (NMR) to smaller and smaller sample volumes has led to the development of a variety of techniques distinct from conventional inductive detection. In this chapter, we focus on the technique of force-detected NMR as one of the most successful in yielding sensitivity improvements. We review the rationale for the technique, its basi...

Techniques for studying molecular structure, such as x-ray diffraction and nuclear magnetic resonance (NMR), often require the use of single crystals' or oriented samples. ' NMR, for example, is sensitive to interatomic distances and angles through spectral splittings caused by internucl. ear dipol. e-dipole couplings in high magnetic field. Where only polycrystalline powders or amorphous mater...

THEORY: The physics behind NMR/MRI signal production lies in the physics of spin. This section will cover enough aspects of spin to understand the generation of NMR signals. Although this initial spin discussion is inherently quantum mechanical in nature, we will later need to employ some simple principles from thermodynamics and classical dynamics to further describe the art of NMR. These topi...

The monitoring of physiological biomarkers is fundamental to the diagnosis and treatment of disease. We describe here the development of molecular sensors which can be read by magnetic resonance (MR) relaxometry. MR is an advantageous bio-sensor readout because it can be determined from opaque samples and through intervening layers of matter. Wash steps can therefore be avoided in in vitro MR a...

The application of nuclear magnetic resonance (NMR) imaging to a stereotactic method is described. The physical properties of NMR offer some important advantages such as good contrast between grey and white matter and the possibility to scan the brain in three planes and at any desired angle. Stereotactic localisation by NMR gives very satisfactory and precise visualisation of the target struct...

SCOPE This review focuses on developments and applications in the field of nuclear magnetic resonance of solids appearing in the literature between October 1999 and October 2001. The review emphasizes uses of solid-state NMR spectroscopy to answer questions about problems in certain areas of chemistry and materials science. As time passes, the use of solid-state techniques to address problems i...

Nuclear magnetic resonance or NMR is one of the most widely used discoveries of Modern Physics. NMR is based on the bulk magnetic properties of materials made up of certain isotopes, most notably, protons (1H), but encompassing a wide variety of species including C, F, and Si. NMR is used to measure magnetic fields with exquisite precision. NMR is used in chemical analysis, oil exploration, and...

Nuclear Magnetic Resonance (NMR) is arguably both the best and the worst technology we have for the implementation of small quantum computers. Its strengths lie in the ease with which arbitrary unitary transformations can be implemented, and the great experimental simplicity arising from the low energy scale and long time scale of radio frequency transitions; its weaknesses lie in the difficult...

Nuclear Magnetic Resonance spectroscopy and imaging can be classified as inductive techniques working in the near- to far-field regimes. We investigate an alternative capacitive detection with the use of micrometer sized probes positioned at sub wavelength distances of the sample in order to characterize and model evanescent electromagnetic fields originating from NMR phenomenon. We report that...
