From The Lab: Nanotechnology
Abstract:
To build useful small devices, engineers must be able to see what they are doing, so they use atomic force microscopes to take pictures with nanometer resolution. To create images, the microscopes move a sharp tip across the surfaces of such tiny objects as silicon transistors or DNA molecules. The tip, just a few atoms across, moves slowly: at best, commercial atomic force microscopes can take only about one image every ten seconds. So they’re not much use in studying fast processes. Now, researchers at MIT have found a way to capture nanoscale images a million times faster.
