Scanning electron micrograph of diamond nanostructures used for the development of a high-sensitivity magnetic field sensor in commercially available AFM systems.

Sensors for magnetometry, possessing a resolution precise to nanometers and a sensitivity in the range of nT*H-1/2, are of great importance for fundamental physics, as well as for life sciences. Among other things, they serve as an important tool for the measurement of magnetic fields of neurons, as a result of which important information for further Alzheimer and pharmacology research can be generated.
