Taking a nanoscale look under the surface

Abstract:
Techniques such as atomic force microscopy provide high-resolution images of a material’s surface, but it's much trickier to look beneath the surface in fine detail. With this in mind, researchers at Northwestern University, US, have come up with scanning near-field ultrasound holography (SNFUH). The method can image buried nanostructures with a spatial resolution of 10–100 nm. The technique suits both hard materials, soft materials, such as polymers and biological structures, and hybrid materials.
