Nanorods could lead to 'superlenses'
Abstract:
Physicists in the US have demonstrated negative refraction at optical wavelengths for the first time. Vladimir Shalaev and colleagues at Purdue University obtained the result in a material consisting of an array of pairs of parallel gold nanorods. The team says the structure is relatively easy to fabricate and could lead to optical "superlenses" that reflect no light and operate with sub-wavelength resolution. Such lenses could be used to make better DVD players and improved biomedical sensors.
