Many laymen will not be aware that science has never been able to X-ray a single atom.
The best that current state-of-the-art synchrotron scanners can manage is to X-ray an attogram—about 10,000 atoms—but the signal produced by a single atom is so weak that conventional detectors cannot be used. Until now.
This landmark feat was achieved thanks to a purpose-built synchrotron instrument at Argonne National Laboratory in Illinois using a technique known as SX-STM (synchrotron X-ray scanning tunneling microscopy).
