Biocompatible technique for nanoscale magnetic field sensing with Nitrogen-Vacancy centers
The possibility of using Nitrogen-vacancy centers in diamonds to measure
nanoscale magnetic fields with unprecedented sensitivity is one of the most
significant achievements of quantum sensing. Here we present an innovative
experimental set-up, showing an achieved sensitivity comparable to the state of
the art ODMR protocols if the sensing volume is taken into account. The
apparatus allows magnetic sensing in biological samples such as individual
cells, as it is characterized by a small sensing volume and full
bio-compatibility. The sensitivity at different optical powers is studied to
extend this technique to the intercellular scale.Comment: 6 pages, 5 figure
