A new form of tunable magnetic resonance imaging agent based on precisely dimensioned cylindrical magnetic nanoshells is introduced. Using top-down prepatterned substrates, the nanoshells are fabricated by exploiting what is usually regarded as a detrimental processing side-effect, namely the redeposition of material back-sputtered during ion-milling. The resulting nanostructures’ well-resolved nuclear magnetic resonance peaks attest to the nanoscale fabrication control and the general feasibility of such sputter redeposition for fabrication of a variety of self-supporting, highly monodisperse nanoscale structures.

In recent years biotechnology and biomedical research have benefitted from the introduction of a variety of specialized nanoparticles whose well-defined, optically distinguishable signatures enable simultaneous tracking of numerous biological indicators. Unfortunately, equivalent multiplexing capabilities are largely absent in the field of magnetic resonance imaging. Corresponding magnetic resonance labels have generally been limited to relatively simple chemically synthesized superparamagnetic microparticles that are substantially indistinguishable from one another. Here we consider instead a top-down microfabrication approach and show how it is possible to effectively encode distinguishable spectral signatures into the geometry of magnetic microstructures. Although based upon different physical principles to those of optically-probed nanoparticles, these geometrically defined magnetic microstructures permit a multiplexing functionality in the magnetic resonance radio-frequency spectrum that is in many ways analogous to that permitted by quantum dots in the optical spectrum. Additionally, in situ modification of particle geometries may facilitate radio-frequency probing of various local physiological variables.
