摘要：Highlights • NV in diamond acts as an atomic size optically detectable spin probe. • The probe combines high magnetic field sensitivity and nanometric resolution. • Non-invasive mapping of functional activity in neuronal networks is one application. • Synapse scale resolution ∼10nm but circuit scale FoV>1mm is possible. Abstract This contribution highlights and compares some recent achievements in the use of k-space and real space imaging (scanning probe and wide-filed microscope techniques), when applied to a luminescent color center in diamond, known as nitrogen vacancy (NV) center. These techniques combined with the optically detected magnetic resonance of NV, provide a unique platform to achieve nanometric magnetic resonance imaging (MRI) resolution of nearby nuclear spins (known as nanoMRI), and nanometric NV real space localization. • Atomic size optically detectable spin probe. • High magnetic field sensitivity and nanometric resolution. • Non-invasive mapping of functional activity in neuronal networks.
