A New Nanolens Broke the Record in Nano-Viewing [report]

Wired has reported about the new lens which broke Resolution Record, by giving the view of visual light images of structures smaller than 100 nanometers (four one-millionths of inch). And this isn't just a normal(perfect) Lens, it uses the new technology which uses a porous surface that actually scatters the light. By measuring how it is scattered and setting up lasers to compensate, they're able to 'steer' the light back to the right spot.

According to Physical Review Letters:

The smallest structures that conventional lenses are able to optically resolve are of the order of 200 nm. We introduce a new type of lens that exploits multiple scattering of light to generate a scanning nanosized optical focus. With an experimental realization of this lens in gallium phosphide we imaged gold nanoparticles at 97 nm optical resolution. Our work is the first lens that provides a resolution better than 100 nm at visible wavelengths.

The smallest object on which physicists have managed to focus a single conventional lens is 200 nanometers across, just larger than the smallest known bacteria (although more complicated microscopy systems have reached down to 50 nanometers). But a lot of structures that physicists and chemists are interested in, like subcellular structures, nanoelectric circuits and photonic structures, are less than half that size.
