Superparamagnetic gadonanotubes are high-performance MRI contrast agents

Chem Commun (Camb). 2005 Aug 21:(31):3915-7. doi: 10.1039/b504435a. Epub 2005 Jul 8.


We report the nanoscale loading and confinement of aquated Gd3+n-ion clusters within ultra-short single-walled carbon nanotubes (US-tubes); these Gd3+n@US-tube species are linear superparamagnetic molecular magnets with Magnetic Resonance Imaging (MRI) efficacies 40 to 90 times larger than any Gd3+-based contrast agent (CA) in current clinical use.
