Three chemists who pioneered a useful technique called click chemistry to join molecules together efficiently have won this year’s Nobel Prize in Chemistry.
Barry Sharpless at Scripps Research in La Jolla, California, and Morten Meldal at the University of Copenhagen laid the foundation for click chemistry, and both independently discovered a pivotal reaction that could link two molecules — an azide and an alkyne — with relative ease1,2,3. This reaction has been used to develop a host of molecules, including plastics and potential pharmaceuticals.
The third winner, Carolyn Bertozzi at Stanford University in California, used click chemistry to map the complex sugar-based polymers called glycans on the surface of living cells without disturbing cell function4. To do this, she developed processes called bioorthogonal reactions, which are now being used to aid the development of cancer drugs.
It’s CRISPR. Two scientists who pioneered the revolutionary gene-editing technology are the winners of this year’s Nobel Prize in Chemistry.
The Nobel Committee’s selection of Emmanuelle Charpentier, now at the Max Planck Unit for the Science of Pathogens in Berlin, and Jennifer Doudna, at the University of California, Berkeley, puts an end to years of speculation about who would be recognized for their work developing the CRISPR–Cas9 gene-editing tools. The technology allows precise edits to the genome and has swept through laboratories worldwide since its inception in the 2010s. It has countless applications: researchers hope to use it to alter human genes to eliminate diseases; create hardier plants; wipe out pathogens and more.Read More »
