Nuclear hyperpolarization can be realized with nitrogen-vacancy (NV) color center incorporated with 13C in nanodiamonds, which can be used as labels for magnetic resonance imaging (MRI). In this work, we employed a combined setup consisting of an atomic force microscope (AFM), a confocal fluorescence microscope, a microwave source, and a spectrometer to study 13C incorporated NV centers in nanodiamonds (ND). Enrichment of 13C in ND was analysed with optically detected magnetic resonance (ODMR) of NV centers. Sizes, fluorescence spectra, and fluorescence intensities of NDs can all be acquired. Therefore, we are able to calculate the density of NV centers. With hyperpolarization of 13C and surface functionalization in the future, our study would promote targeted MRI, which owes great significance in medical and biological applications.
