article_snippet: Professor Connie Chang-Hasnain, a member of the University of California Berkeley team that developed the material made the material by etching features smaller than a wavelength of light onto a silicon film one thousand times thinner than a human hair.
article_snippet: Engineers made the material (illustrated) by etching features smaller than a wavelength of light onto a silicon film one thousand times thinner than a human hair .
article_snippet: To make the material, the Berkeley team etched rows of ridges onto a thin layer of silicon, which was set into a layer of silicone for flexibility.
