Nobel Prize for 3 chemists who made molecules ‘click’

Nobel Prize in Chemistry winner Morten Meldal meets the press in front of the entrance to University of Copenhagen, Denmark, Wednesday Oct. 5, 2022. This year’s Nobel Prize in chemistry has been awarded in equal parts to Carolyn R. Bertozzi and K. Barry Sharpless from the United States, and Danish scientist Morten Meldal for developing a way of “snapping molecules together" that can be used to design better medicines.

Three scientists were jointly awarded this year's Nobel Prize in chemistry on Wednesday, Oct. 5, 2022 for developing a way of “snapping molecules together” that can be used to design better medicines, including ones that target diseases such as cancer more precisely. Americans Sharpless and Carolyn R. Bertozzi and Danish scientist Morten Meldal were cited for their work on click chemistry and bioorthogonal reactions, which are used to make cancer drugs, map DNA and create materials that are tailored to a specific purpose.
