Quantum sensing has emerged recently as the breakthrough application of spin defects in solids. In this regard, negatively-charged nitrogen vacancy centers (NV) in diamond are presented as ultrasensitive sensors of magnetic field [1], electric field [2], temperature [3], stress and pressure [4,5], and force [6]. Here, ultrasensitive measurement of mass employing NV centers as embedded nanosensors in diamond micromechanical oscillators is discussed. Different techniques such as optical readout of the oscillator position and ODMR-based measurements are analytically discussed and compared. This is followed by a demonstration of the experimental realization of the platform and mass-sensing results.
