Steps toward a new imaging method in biological systems — •Gerhard Wolff, Simon Schmitt, Christian Osterkamp, Liam McGuinness, Boris Naydenov, and Fedor Jelezko — Institute for Quantum Optics, University Ulm, Germany

In the last century NMR established itself as key technology for non-destructive investigation of molecules and chemical reactions. As traditional NMR is reaching its limits in sensitivity and in spatial resolution new ways a new approach is needed ti reach behind these limitations.

In the last decades quantum sensors have attracted more and more attention. One such quantum sensor is the nitrogen Vacancy (NV) center in diamond for which research groups recently showed nanoscale NMR spectroscopy using single molecule confocal microscopes.

Widefield microscopy has the advantage over single NV experiments that it allows one to increase the signal and reduce measurement time, thus increasing frequency sensitivity. The reduced spatial resolution is still sufficient for imaging of single cells.

However several challenges still remain, such as homogeneous magnetic fields over several hundred micrometers while still being adjustable in arbitrary directions as well as the generation of homogeneous microwave fields for coherent control of the NV ensemble.

This work seeks to develop recent groundbreaking experiments and establish a new imaging method for biological systems.
