Using a state-of-the-art atomic force microscope, the scientists have taken the first atom-by-atom pictures, including images of
the chemical bonds between atoms, clearly depicting how a molecule’s structure changed during a reaction. Until now, scientists
have only been able to infer this type of information from spectroscopic analysis.

“Even though I use these molecules on a day to day basis, actually being able to see these pictures blew me away. Wow!”
said lead researcher Felix Fischer, UC Berkeley assistant professor of chemistry. “This was what my teachers used to say
that you would never be able to actually see, and now we have it here.”

The ability to image molecular reactions in this way will help not only chemistry students as they study chemical structures and reactions,
but will also show chemists for the first time the products of their reactions and help them fine-tune the reactions to
get the products they want. Fischer, along with collaborator Michael Crommie, a UC Berkeley professor of physics, captured these images
with the goal of building new graphene nanostructures, a hot area of research today for materials scientists because
of their potential application in next-generation computers.

“However, the implications go far beyond just graphene,” Fischer said. “This technique will find application in the study of
heterogeneous catalysis, for example,” which is used widely in the oil and chemical industries. Heterogeneous catalysis involves
the use of metal catalysts like platinum to speed reactions, as in the catalytic converter of a car.
