Clearly the most attractive super hero power for nanotechnology at the moment is invisibility. Last month we had a nano-enabled coating that managed to make aircraft invisible to radar. Now we have a metamaterial consisting of fishnet-like film containing holes about 100 nanometers in diameter that could serve as an invisibility cloak.
While I personally might be persuaded to choose Spider-like climbing abilities for my nano-enabled super hero power, invisibility does pose an attractive option.
However, invisibility is far from the point of this research conducted at the Birck Nanotechnology Center, Purdue University and appears in the August 5th edition of the journal Nature.
