Abstract

Nanodiamonds containing the Nitrogen-vacancy (NV) centre are emerging as a unique platform for nanoscale sensing in biological systems. There is particular interest in the capability of sensing subcellular changes of magnetic and electrical fields, temperature, and pressure. However, the sensitivity of such nanodiamond particles with NV centre as a probe is highly dependent on the relative location and polarisation of the NV centre to the bulk of the particle. Here we show the optical scattering from an NV centre in a nanodiamond as a function of position and orientation within the nanodiamond. The scattering fields are obtained by using the recently developed robust non-singular surface integral equation method.^{1, 2} Our results highlight a new pathway to nanodiamond characterisation which may be useful in teasing out the various effects of surface morphology, surface termination, and formation details, which ultimately may benefit the optimisation of diamond production for nanoscale biosensing applications.
