Molecular machines

This film derives from the Nanosciences and Nanotechnologies DVD.
Jean-Pierre Sauvage of the Laboratoire de chimie organo-minérale (laboratory of inorganic chemistry) presents the philosophy of his work as what he calls a "molecularist". His team seeks to produce molecules with non-trivial topological properties, i.e. with intertwining chains.
If the different parts of these molecules can be set into relative motion, one obtains molecular machines or motors. Such discoveries are often inspired by biology, which shows that such molecules exist and work.
