Physicist Michel Orrit new member KNAW

The Royal Netherlands Academy of Arts and Sciences (KNAW) selects prominent researchers as members based on their scientific achievements. On September 17th, the KNAW will install 21 new members, including Leiden physicist Michel Orrit.

Michel Orrit has laid the foundation for single-molecule optics. He developed a sensitive technique that uses laser light at specific wavelengths to illuminate individual molecules. At first, this applied only to fluorescent molecules, but later Orrit broadened the technique so that it also worked on 'dark' molecules. One of his most recent achievements is scanning the conditions in a cell using gold nanoparticles. Orrit's methods enable scientists to unravel many kinds of physical and chemical processes in living matter. In 2017 he was awarded the NWO Spinoza Prize—the highest Dutch scientific award.
