STOCKHOLM: A trio of chemists from the United States and Denmark who laid the foundation for a more functional form of chemistry where molecules are snapped together on Wednesday won the Nobel Chemistry Prize.
Americans Carolyn Bertozzi and Barry Sharpless, together with Denmark's Morten Meldal, were honoured "for the development of click chemistry and bioorthogonal chemistry", the jury said.
Bertozzi is the only woman among the seven Nobel laureates honoured so far this year, with women vastly under-represented in the history of the prizes, especially in the science disciplines. The award marks the second Nobel for 81-year-old Sharpless, who won the chemistry Nobel in 2001.
Only four other individuals have achieved the feat of winning two Nobel Prizes, including Polish-born Frenchwoman Marie Curie, who won the chemistry prize in 1911 after first winning the physics prize in 1903.
She was followed by American Linus Pauling who won for chemistry in 1954 and peace in 1962. American John Bardeen won the physics prize in 1956 and 1972, and Britain's Frederick Sanger won the chemistry prize in 1958 and 1980.
Click chemistry "is an elegant and efficient chemical reaction that is now in widespread use," the jury said in a statement.
"Among many other uses, it is utilised in the development of pharmaceuticals, for mapping DNA and creating materials that are more fit for purpose," it added.
Sharpless, a professor at Scripps Research in California, "started the ball rolling" and "coined the concept of click chemistry" around 2000, the jury said.
Afterwards, Sharpless and Meldal, a professor of chemistry at the University of Copenhagen, "independently of each other, presented what is now the crown jewel of click chemistry: the copper catalysed azide-alkyne cycloaddition". -- AFP
