Technology Review: A Superlens That Assembles Itself
Rated • 1 review • nanotech • technologyreview.com
'Kim's team make the tiny spherical lenses by evaporating a solution containing cup-shaped organic molecules. First, the molecules, which are based on carbon rings, are dissolved in an organic solvent; then water is added, and the solution is allowed to slowly evaporate. During the evaporation process, the organic molecules form crystalline nanotubes that form the lenses. By changing the temperature and the evaporation rate, Kim says, it is possible to control the lenses' ultimate size. Once the lenses have formed, they're stable. The work is described in a paper published today in the journal Nature.'
