Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale structures. However, even the most powerful optical microscopes have been limited by a fundamental physical rule known as the diffraction limit, which prevents them from clearly seeing anything smaller than about 200 nanometers—far too large to capture single atoms. This limitation has …
