Carbon-nitrogen bonds are the stuff pharmaceuticals are made of. And according to Cornell University, they’re so essential that over 85 percent of the top selling pharmaceuticals have at least one carbon-nitrogen bond. That is to say, advances in carbon-nitrogen bond technology would mean great advances to the drug industry.

Song Lin, a Cornell University researcher in the chemistry and chemical biology field and ECS member of the organic and biologic division, is working on doing just that. He says that with electrochemistry, a process that directly uses electricity to drive chemical reactions, it would be possible to create carbon-nitrogen bonds in a sustainable manner. The only problem is that electrochemical reactions often do not offer the chemical selectivity and efficiency needed to accomplish a particular transformation – a problem Lin and his team are working to solve.

Until now, the idea of controlling reactions with the light from lasers was only theoretical. However, new research shows that a laser pulse has the ability to control the formation of a molecular bond between two atoms.

Due to this new development, researchers can now control the path of the chemical process with extreme precision.

This from APS Physics:

For the first time, researchers demonstrate the coherent control of the reaction by which two atoms form a molecule. The achievement—coupled with other photocatalyst tools—could potentially lead to a chemical assembly line, in which lasers slice and weld molecular pieces into a desired end product.
