Numerous works have been devoted to the development of efficient probes for nanoscale imaging. I will report the application of optically and magnetically active nanodiamonds to nanoscale mapping using the unique properties of the nitrogen-vacancy (NV) color center. The NV center is hosted in a diamond nanocrystal which is attached to the tip of an atomic force microscope. Combining nanometer scale spatial resolution, high sensitivity and room temperature operation, this NV-based scanning microscope opens up numerous perspectives in nanotechnology.
