This man (and his group) developed a rotaxane structure that could act as a molecular shuttle
What is Sir James Fraser Stoddart
300
These type of molecules have a ring and an axle, but without stoppers.
What is
pseudorotaxane?
300
The two types of conversions that allow the wheels of the nanocar to rotate and create movement.
