Nobel Prize in Chemistry 2016 - Molecular Machines


Prof. Andrej Vilfan

Faculty of Mathematics and Physics, University of Ljubljana & J. Stefan Institute, Ljubljana


The Nobel Prize in Chemistry 2016 was awarded to Jean-Pierre Sauvage, J. Fraser Stoddard and Ben L. Feringa for the design of synthetic molecular machines. Their central innovation was to use "mechanical bonds" such as topologically entangled rings that can be moved or rotated without significant energy barriers, to create artificial molecular motors. These can be set in motion by light or by changes in the chemical environment.  In the talk I will discuss the general principles underlying molecular motors and compare them with naturally occurring motor proteins and some more recent ideas for artificial biomolecular motors.
