Planar scanning probe microscopy - a technique invented by our group - has achieved another milestone. It can now acquire magnetic field maps, using NV centers in diamond as a scanning magnetic field sensor. In contrast to existing schemes, we can employ several NV centers as independent sensors in the same sensor. In a new publication, we demonstrate that this ability can be used to record maps of the three-dimensional vector magnetic field.

We have developed an interferometric microscopy scheme which can detect action potentials in paralyzed cardiomyocyte cells without using  fluorescent voltage or calcium indicators. You can read more about this scheme in our publication

Congratulations to our PhD student Mohammad Amawi, who just won the prize for the best poster on the conference  "International AGYA Winter School: Quantum Materials for Energy and Environmental Applications" of the German-Arab Young Academy AGYA, hosted at the University of Sharjah (UAE)!

Our latest result just appeared in npj Quantum Information!

We have taken a three-dimensional image of single NV centers spins in a diamond by magnetic resonance tomography. We reach a resolution in the single-nanometer range, which can likely be pushed to the atomic scale in a future improved version of our nanoscale magnetic resonance scanner.
