In this paper, we provide a review of the recent advances in miniaturizing nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) spectrometers for portable magnetic resonance (MR) applications. We focus the discussion on the application of integrated circuit technology for the miniaturization of the NMR and EPR spectrometer hardware and/or the detector and we will briefly touch on magnet technology. Finally, we will summarize current challenges of chip-integrated spectrometers and give an outlook on future applications of mobile MR spectrometers.
