Abstract
Optical tweezers have been celebrated in 2018 with the Nobel Prize in Physics awarded to Arthur Ashkin. We trace here the history of this technique, which has proven essential for the discovery of several mechanisms of Life. The technique relies on optical forces and results from the momentum transfer between light and objects, usually of micrometer size. Particularly suitable for the study of molecular machines, optical tweezers also shed light on the mechanics of cells in vitro or in living organisms. [ABSTRACT FROM AUTHOR]
