Synthesis and magnetism of ε-Fe3N submicrorods for magnetic resonance imaging

Abstract

Fe₃N submicrorods with desirable magnetic properties were prepared from a designed metal–organic framework precursor via a modified ethanediamine nitridation route. Magnetic resonance imaging using the Fe₃N submicrorods was investigated carefully, confirming the Fe₃N submicrorod could be acceptable as a significant contrast agent for its outstanding concentration dependent signal and high r₂ relaxivity. Besides, the excellent saturation magnetization and homogeneous dispersity also developed the Fe₃N application range.
