This year’s Nobel Prize in chemistry has been awarded in equal parts to Carolyn R. Bertozzi, Morten Meldal and K. Barry Sharpless for developing way of “snapping molecules together” that can be used to design medicines.
Their work, known as click chemistry and bioorthogonal reactions, is used to make cancer drugs, map DNA and create materials that are tailored to a specific purpose.
Hans Ellegren, secretary general of the Royal Swedish Academy of Sciences, announced the winners Wednesday at the Karolinska Institute in Stockholm, Sweden.
Bertozzi is based at Stanford University in California, Meldal is at the University of Copenhagen, Denmark, and Sharpless is affiliated with Scripps Research, California.
Sharpless previously won a Nobel Prize in 2001. He is the fifth person to receive the award twice.
Last year the prize was awarded to scientists Benjamin List and David W.C. MacMillan for finding an ingenious and environmentally cleaner way to build molecules that the Nobel panel said is “already benefiting humankind greatly.”
They continue with literature on Thursday and the 2022 Nobel Peace Prize to be announced on Friday, with the economics award on Oct. 10.
