Filling Fullerenes (IMAGE) Virginia Tech Caption Lead rods, which are infused with the material to be encapsulated in hollow carbon molecules known as fullerenes, are blasted with a plasma arc. The resulting soot contains the filled carbon molecules. The remote-control process was invented to insert radio-labeled materials into fullerenes for use in diagnosing and treating tumors. Brain tumors are the target of the NIH-funded research being carried out by a Virginia Tech-Virginia Commonwealth University team.
