They also have molecular snippers - enzyme catalysts - that cut the grass on to which they're clasped. So, while the other legs remain fixed, the newly free one waves around until it finds a new ...

The team first used their STM to locate a methylaminocarbyne (CNHCH 3) molecule that was fixed to a platinum surface. Then they turned up the voltage, increasing the flow of electrons.

Physicists of Ludwig-Maximilians-Universitaet in Munich, Germany, have now developed a model that predicts these patterns and thus allows optimization of the molecular synthesis in the future.

For example, if we can better understand DNA at an atomic and molecular level, that will help us fine-tune and tailor health care according to patients’ needs. The possibilities are endless. A big ...

Using an ultra-thin and sharp needle tipped with a single carbon monoxide molecule frozen to minus 266 degrees centigrade, researchers from the University of Warwick and Cardiff identified and ...
