New technique tracks individual protein movement on live cells
(PHYSorg.com Chemistry)

The piece of gold that Richard Taylor was thrilled to track down weighed less than a single bacterium. Taylor, a postdoctoral fellow at the Max Planck Institute, was working to follow individual nanogold-labeled molecules that move just nanometers, billionths of a meter. The resulting microscopy technique, developed under Professor Vahid Sandoghdar and colleagues, can follow proteins at microsecond speeds for long periods and will be presented today at the 64th Annual Meeting at the Biophysical Society in San Diego, California.
