Abstract

In this paper, we demonstrate a novel type of contrast agent with multiplexing capability for use in magnetic resonance imaging (MRI) applications. Keeping biocompatibility in mind, iron and several iron oxide thin films with varying magnetic properties were prepared and characterized using a superconducting quantum interference device (SQUID). Double-disk shaped particles constructed with iron and iron oxide disks separated by polyimide posts were fabricated and validated using an MRI scanner. Spectral tunability was achieved by varying both the geometry and the magnetic properties of the particles.
