Microscopy: A terahertz nanoscope

Replacing the 'micro' in microscope with 'nano', and using invisible light instead of visible, won't give scientists an instrument that can image nanostructures — unless they first beat the system's diffraction limit.

It requires a bit of imagination to think about using invisible light to look at an object of nanometre dimensions. Yet this is precisely what Huber and co-workers have done in a study described in Nano Letters1.
