Targeted Delivery of Nanodiamonds into Living Cells
Techniques developed in AMO physics has long served as foundations for various imaging modalities in chemistry and biology. Magnetic resonance imaging (MRI) is one such example: through the mapping of proton nuclear spin resonances under the magnetic field gradient, MRI enables both structural and functional imaging of our bodies in an unprecedented detail. Magnetometry using nitrogen vacancy (NV) centers in diamond,1 which was developed as a part of our previous CUA efforts, has the potential to advance magnetic resonance imaging to new heights in terms of sensitivity and spatial resolution. By coupling nanoscale fluorescence imaging with exquisite sensitivity to the local magnetic environment, this technique may enable imaging of individual biological molecules and the sensing of nanoscale electric and magnetic fields within a single living cell.
