A sound way to see nanostructures
Abstract:
Ultrasound can be used to image nanostructures, a team of US scientists has shown. The spatial resolution of acoustic imaging, in which sound waves are scattered from the sample under study, is normally around 1–10 µm. But Brian Daly, of the University of Michigan in Ann Arbor, and co-workers have found a way to increase the resolution to around 700 nm.
