Mitragotri reckons that the particles could provide a way to get drugs into the body at a more constant concentration, or substances such
as iron oxide nanoparticles, which increase contrast in magnetic resonance imaging.

One promising idea, known
as magnetic hyperthermia, involves injecting minuscule «
nanoparticles,» basically microscopic lumps of
iron oxide or other compounds, into tumors to make them magnetic.
As an alternative, contrast agents based on
iron oxide nanoparticles are practically unused because of the difficult readability of the results.
HYEON Taeghwan, director of the Center for
Nanoparticle Research explains: «Let's take the example of a MRI analysis of a brain with Alzheimer's:
iron oxide in the blood vessels would appear
as black and the amyloid plaques
as gray.
The nanoscrolls can be visualized
as traditional «Swiss rolls» where the sponge - cake represents the graphene, and the creamy filling is the
iron oxide nanoparticles.
I've been experimenting with T10 dextran coated
iron oxide nanoparticles, obviously not the same
as fullerenes, but still a very interesting tool, I've been testing if the coating is giving the particle antioxidant abilities because of it's the (basically) indigestable sugar chains (glucose) creating a high surface area which are largely made from hydroxyl groups, I hypothesised this act's
as a «sink» for reactive oxygen species converting them to water.
