RF design constraints are simpler to manage at smaller size scale.  This is obvious from the complexity that has been achieved in modern desktop computers, where miniaturization and integration have provided functionality that far surpasses that of large, mainframe computers of decades prior, at a fraction of the cost.  The electrical properties of microcoils make them amenable to novel forms of RF isolation that is not feasible at larger size scales, making it possible to include multiple nuclear frequencies on the microcoil.  This is contrary to conventional heteronuclear probes, where “inner” and “outer” coils are employed, and where sacrifices in sensitivity are made to “outer” coil nuclei and to minimize the number of nuclei present on the “inner” detection coil.  With microcoils, all nuclei are channeled to the primary coil, and reception can be accomplished with negligible penalty in 1H sensitivity, while supporting alternative nuclei (e.g.. 13C) on the same coil.  One high quality coil for all nuclei, used for both transmission and reception – this is CapNMR sensitivity, simplicity, and economy working together.
