Superlens could image nanoscale with light

Abstract:
Physicists in the US have made an optical superlens from a thin layer of silver. The lens has a negative refractive index and can be used to image structures with a resolution that is about one sixth the wavelength of light - thus overcoming the so-called diffraction limit. Xiang Zhang and colleagues at the University of California at Berkeley say that the lens could have many applications, such as imaging nano-scale objects with light.
