Abstract

A new form of tunable magnetic resonance imaging agent based on precisely dimensioned hollow cylindrical magnetic nanoshells is introduced. Using top-down prepatterned substrates, the requisite 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 level of fabrication control and the feasibility of such sputter redeposition for parallel fabrication of various other self-supporting monodisperse nanostructures.
