They have been honoured "for the development of click chemistry and bioorthogonal chemistry."
With this innovation, scientists can create new types of biomolecules and other materials to deliver drugs precisely to the specific point in the body that is ailing.

What is 'click chemistry': A process to click or join complicated molecules in an easy and fast way without creating unwanted byproducts. Barry Sharpless together with Morten Meldal has worked to develop this phenomenon. Whereas Bertozzi took the 'Click Chemistry' to another level by developing "Bioorthogonal" reactions that operate safely inside living organisms without disturbing their bodily processes and biochemistry.
Click Chemistry and "Bioorthogonal" Reactions both have applications in the field of medical science and pharmacy. With their help, we can specifically target ailing cells and tissues to cure many diseases such as cancer. It also helps in investigating cells and tracking biological processes that can help in further research and innovations.
This is the second chemistry Nobel for Barry Sharpless who had gotten it even in 2001 for his work on "chirally catalysed oxidation reactions". Four other scientists have won two Nobels: John Bardeen, Marie Curie, Linus Pauling and Fred Sanger.
Bertozzi is only the eighth woman to win the chemistry prize in Nobel history.
