The 2022 Nobel Prize in Chemistry was awarded on Wednesday 5 October to the Americans Carolyn Bertozzi and Barry Sharpless and to the Danish Morten Meldal for their work on “click” and “bio-orthogonal” chemistry.announced the Nobel Committee of Stockholm (Sweden).

Barry Sharpless, 81, is only the fifth person to win a Nobel Prize twice. He had already won the chemistry prize in 2001 for his discoveries on the asymmetric catalysis technique.

The California-based American researcher and 58-year-old Dane Morten Meldal of the University of Copenhagen are crowned for their pioneering work in “click chemistry,” a new form of combining molecules. This is used in particular to develop pharmaceutical treatments, map DNA or create new materials.

55-year-old American Carolyn Bertozzi is sacred for the invention of bio-orthogonal chemistry, a chemical reaction described as being able to trigger in a living organism, but without disturbing or modifying its chemical nature.

Germany’s Benjamin List and Britain’s David Macmillan were honored in 2021 for inventing a new type of catalyst to produce new molecules, at a lower cost and in a cleaner way. In 2020 the French Emmanuelle Charpentier and the American Jennifer Doudna were awarded for “molecular scissors”.
