Scientists use X-ray to identify single atom for first time

Scientists have successfully detected the first X-ray signal from a single atom, a breakthrough that could have profound implications for quantum information, nanotechnology, and scientific research. The study, led by Argonne National Laboratory scientist Saw Wai Hla, utilized a purpose-built synchrotron X-ray instrument to identify the type and chemical state of individual atoms. This achievement, published in the journal Nature, opens up new possibilities for atom-level analysis and understanding.
