Limitations of traditional nuclear magnetic resonance (NMR) can be overcome by using Nitrogen vacancy (NV) centers in diamond as local NMR probes which rely on statistical rather than thermal polarisation.
Proof-of-concept NMR measurements with NV centers have successfully been demonstrated in the past but revealed new challenges. One of them being the fast diffusion of molecules in liquids out of the detection volume, prohibiting NMR sensing by the NV centers. This can be solved by confining liquids in close proximity to the NV sensor. We realized this by structuring the diamond surface with nanowells, which function as traps for zeptoliter scale samples. In addition we demonstrated the controlled creation of NV centers underneath these nanostructures. We present NMR data measured with NV centers in such devices.
The promising technique of nanoscale NMR using NV centers is not restricted to liquids though but can be applied to a wide variety of materials. We will discuss a selection of potential applications.
