Techniques: NMR on a chip
Robert Tycko1
Abstract
If a nanoscale gallium arsenide structure is excited with an oscillating magnetic field, superpositions of nuclear spin states can be created and detected electrically. Quantum computing could be the beneficiary.
Nuclear magnetic resonance (NMR) spectroscopy is a near-ubiquitous technique in the physical and biological sciences. Applications include the verification of molecular structures in synthetic chemistry, investigation of superconductivity in solid-state physics, the determination of protein conformations in structural biology, and diagnostic imaging in medicine.
