Scientists Capture the X-ray Fingerprint of a Single Atom for the First Time And This Could Change Everything [Video]

In a quiet lab at Argonne National Laboratory, Saw-Wai Hla and his team were huddled around their instruments late one night when they detected the spectral signature they had been searching for. The excitement in the room was electric. After more than a decade of research, they had done it. They had captured the X-ray fingerprint of a single atom.

For Hla, a professor at Ohio University and physicist at Argonne, the discovery was a career-defining moment. “I could not sleep for probably two, three days,” Hla recalls. “It was one of the best moments of my life.”

When Wilhelm Roentgen first discovered X-rays in 1895, he couldn’t have imagined how far this technology would advance. From revolutionizing medicine to exploring the surface of Mars, X-rays have become indispensable across various fields. Yet, despite these leaps, one goal remained elusive for over a century: detecting the X-ray signature of a …
