Nuclear magnetic resonance spectroscopy (NMR) and imaging (MRI) are important non-destructive investigative techniques for soft matter research. Continuous advancements have not only lead to more sensitive detection, and new applications, but have also enabled the shrinking of the detectable volume of sample, and a reduction in time needed to acquire a spectrum or image. At the same time, advances in microstructuring and on-chip laboratories have also continued unabated. In recent years these two broad areas have been productively joined into what we term micro nuclear magnetic resonance (mMR), an exciting development that includes miniaturized detectors and hyphenation with other laboratory techniques, for it opens up a range of new possibilities for the soft matter scientist. In this paper we review the available miniaturization technologies for NMR and MRI detection, and also suggest a way to compare the performance of the detectors. The paper also takes a close look at chiplaboratory augmented mMR, and applications within the broad soft matter area. The review aims to contribute to a better understanding of both the scientific potential and the actual limits of mMR tools in the various interdisciplinary soft matter research fields.

“…The choice and construction of coils depend on sample size and the frequency used [30]. Other parameters must also be taken into account [35][36][37], such as the SNR, B 1 homogeneity, electric field (risk of overheating) and B 0 field used for the MR experiments.…”

“…At higher frequencies, however, tuning long solenoid coils with large number of turns to the desired frequency appears very difficult. Often only coils with fewer than five turns can be used . Consequently, the standard solenoidal coils in high‐field MRI scanners turn out to produce a very limited region of homogenous magnetic field along the length of the coil, so that more sophisticated coil designs are required …”

Full‐wave electromagnetic simulations have been employed to analyze the design approaches that allow for solving the problems preventing inductive performance of micro‐solenoidal RF probes and formation of strong and homogeneous magnetic fields inside probes at the studies of millimeter‐range sized objects in 14 T MRI scanners. In particular, the effects of non‐uniform coil wrapping on field homogeneity inside extended coils and of partitioning the coils by dielectric separators on coil self‐resonances have been investigated. The possibility to utilize tunable C‐C matching circuits with the coils and to mitigate the effects of sample insertion on the probe resonance frequency has been demonstrated. Challenges of coil fabrication have been also addressed.
