Made a clear picture of individual parts of molecules

As a result of the collaboration of Chinese and Finnish scientists, it was possible to obtain an image of the structure of high detail nanoparticles, up to the determination of individual parts of molecules.

The group investigated silver nanoparticles (374 atoms), coated with thyola t-butylbenzene molecules having three different carbon groups at the ends. During scanning with tunnel microscopy (STM) at a low temperature, sequential transparent modulations are distinguishable (image on the left). Simulation showed that each carbon coating group is capable of passing a different maximum current (image on the right) and distances between highs corresponding to the results of the STM measurement.

This confirmed that the measurement was successful at the submolecular level. Modeling also predicted that the exact measurement will not be successful at normal temperature, since the thermal movement of molecules is so large that the maxima of individual carbon groups are mixed with the background. According to scientists, this is the first case when with the help of STM visualization of surface structures of nanoparticles managed to distinguish between individual elements of molecules.
