Abstract

Abstract : Ultra small Gd 3+ /[Fe(CN)6 ] 3− nanoparticles are investigated in vivo as contrast agents for Magnetic Resonance Imaging. Abstract : Cyano-bridged Gd 3+ /[Fe(CN)6 ] 3− coordination polymer nanoparticles of 3–4 nm stabilized withd -mannitol presenting a high r 1 relaxivity value of 11.4 mM −1 s −1 were investigated in vivo as contrast agents (CA) for Magnetic Resonance Imaging (MRI). They allow an increase of the MR image contrast and can act as an efficient intravascular T 1 CA with a relatively long blood-circulation lifetime (60 min) without specific toxicity.
