Relaxometry with Nitrogen Vacancy (NV) Centers in Diamond

Accounts of Chemical Research (2022) 

Relaxometry, using diamonds with Nitrogen-Vacancy (NV) centers, is a precise method for measuring tiny magnetic changes at the nanoscale. In this process, NV centers in diamonds—defects where nitrogen replaces carbon—are aligned by a laser pulse and emit fluorescent light upon returning to their normal state. This technique, crucial in detecting magnetic fields influenced by their surroundings, is especially valuable in biological research for identifying and analyzing free radicals within cells, offering significant insights into complex biological processes and diseases.
