Under the direction of Professor Saw Wai Hla, a group of researchers from Ohio University, Argonne National Laboratory, the University of Illinois at Chicago, and other institutions have made a significant advancement in the first-ever detection of the X-ray signature of a single atom. They identified and examined individual atoms using synchrotron X-ray scanning tunneling microscopy (SX-STM), a cutting-edge method. This accomplishment, funded by the Office of Basic Energy Sciences at the U.S. Department of Energy, has the power to completely alter the fields of environmental, medical, and quantum research.

Since their invention in 1895, X-rays have been used extensively, from security checks to medical examinations to even the analysis of materials on Mars. Understanding the material composition of a sample is a crucial application of X-rays in science. The quantity of samples needed for X-ray detection has decreased over time significantly as a result of improvements in synchrotron X-ray sources and equipment. Due to the incredibly weak signal that a single atom produces, it has been difficult to detect an individual atom using X-rays. Such weak signals cannot be detected by conventional X-ray detectors due to their lack of sensitivity.

Professor Hla claims that it has long been a goal of science to be able to X-ray a single atom, and his research team has now achieved this goal. They were able to record the X-ray signature of a single atom using synchrotron X-ray scanning tunneling microscopy, which is a significant advancement in the field of X-ray detection. This discovery expands research opportunities and may have broad ramifications across a number of industries.
