Acoustic nuclear magnetic resonance

As indicated above, for solids it is possible to transfer energy between nuclear spins and the lattice via phonons generated within the sample. Kastler [4] and Altershulter [5-7] proposed that it should also be possible to utilize this path in reverse, with applied phonons (ultrasound) causing a nuclear spin system to experience a net absorption of energy, and result in detectable acoustic nuclear magnetic resonance (ANMR) spectra.

However, the determination of affinity does not necessarily have to rely on labeled ligands. It is also possible with native ligands when using suitable detection methods, as for example nuclear magnetic resonance (NMR), surface plasmon resonance (SPR), acoustic biosensors or calorimetry [48, 49]. A particularly versatile and sensitive detection principle for the investigation of interactions between targets and native ligands is mass spectrometry [50].

Density measurements are closely akin to liquid level measurements because both are often required simultaneously to establish the mass contents of a tank, and the same physical principle may often be used for either measurement. Thus, the methods of density determination include the techniques of direct weighing, buoyancy, differential pressure, capacitance, optical, acoustic, ultrasonic, momentum, rotating paddle, transverse momentum, nuclear radiation attenuation, and nuclear magnetic resonance. Each of the principles involved will be discussed along with its relative merits and shortcomings.
