New quantum dot technique combines best of optical and electron microscopy

It's not reruns of "The Jetsons", but researchers working at the National Institute of Standards and Technology have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture—cathodoluminescence—to image nanoscale features. Combining the best features of optical and scanning electron microscopy, the fast, versatile, and high-resolution technique allows scientists to view surface and subsurface features potentially as small as 10 nanometers in size.
