Forcing fullerenes forward! The tip of a scanning tunneling microscope induces the manipulation of a C60 molecule (see image), displacing it across a Si surface. The results imply that the molecule is stabilized at intermediate positions between the expected adsorption sites. This is attributed to the formation of tip–molecule covalent bonds, which, in combination with molecule–substrate interactions, result in quasi-continuous constrained manipulation of the molecule.
