Colloquium "Prix Nobel de Physique 2018"
Colloque
Amphithéâtre "PIERRE GLORIEUX" CERLA
MARDI 26 MARS 2019, 10h45
Professor Felix Ritort, Small Biosystems Laboratory, University of Barcelona (Spain) Title: Optical tweezers and their applications to biophysics Abstract: “Take a single DNA molecule and pull from its extremities while recording the force-extension curve until it gets fully straightened”. This thought experiment, which was just a dream a few decades ago, has now become standard in many research institutes worldwide. Optical tweezers are a fabulous tool for manipulating and monitoring the direct action of biological molecules at the individual level, as well as measuring forces in the piconewton range and energies of one kilocalorie per mole. The Nobel Prize in Physics 2018 has been awarded to inventions in the field of laser physics: one half of the award to the American Arthur Ashkin for the invention of the optical tweezers, the other half to the Frenchman Gerard Mourou and the Canadian Donna Strickland for the generation of pulses of light from intense and ultra-fast beams. In this talk I will present a brief overview of how the invention of optical tweezers has revolutionized research in physics, chemistry and biology.
