The synthetic motor molecule, rotaxane, linearly shuttles its positively charged ring element through a redox reaction of the neutral, though electron rich, TTF unit. 
By using an Atomic Force Microscope (AFM), we can probe the repulsive force provided by the TTF2+-ring interaction and thereby determine the switching force of an individual rotaxane motor molecule.
