Controlling single-outcome single-molecule reactions is ... using the atomic resolution of a scanning tunneling microscope (STM). Conventional microscopes use light and lenses to magnify specimens ...

The tip of the STM (yellow) assumes the role of a hard drive's reading and writing head for the molecule attached to the copper nitride surface (black).

In this method, known as the STM breakjunction technique ... which allowed them to be sure they have trapped just a single molecule. They also measured the length of the molecular junctions ...

Depending on the position of these two atoms, the lowest unoccupied molecular orbital of the molecule can have one of two orientations. Using a low-temperature scanning tunnelling microscope (STM ...

"Stretching DNA refers to the process of stretching a single DNA molecule, which is originally coiled in a random coil, into a straight line," Azuma said. "The length and structure of a single DNA ...

What is the size of a single molecule of oil? What may initially seem like a trick question – answerable only through the use of complicated, high-tech scientific equipment – is actually as ...
