摘要：

Nanoparticles of superparamagnetic magnetite have been strongly attached to single-walled carbon nanohorns (SWNHs) by using a simple method, namely the deposition of iron acetate clusters on SWNHs followed by heat treatment. The attached magnetite nanoparticles induce remarkable darkening of the magnetic resonance images, which allowed in vivo visualization (see figure) of the accumulative behavior of SWNHs in the spleen and kidneys.
