Detector can count atom by atom

More than 80 years have passed since Louis de Broglie discovered that matter can act like a wave as well as a particle. With advances in technology, scientists have recently begun exploiting this strange property of everyday matter for applications such as atom lasers and nanofabrication. To further their understanding of these applications with matter waves, however, scientists need a way to detect and count the exact number of atoms used.
