The ring of Gyges on the cheap?

Postby Timothy Chase » Fri Mar 09, 2007 9:25 pm

Gold nanorods suggest cheap manufacture of metamaterials...

The author wrote:Rice University chemists have discovered that tiny building blocks known as gold nanorods spontaneously assemble themselves into ring-like superstructures.

This finding, which will be published as the inside cover article of the March 19 international edition of the chemistry journal Angewandte Chemie, could potentially lead to the development of novel nanodevices like highly sensitive optical sensors, superlenses, and even invisible objects for use in the military.

For those who are interested, a couple of earlier technical articles in the field of metamaterials...

PS

"Metamaterials" is a topic that came up among a few of us a few months ago, and given this, I thought it might be nice to share more recent news - even though it presumably has nothing to do with evolution. However, looking at some of the more recent articles on the assembly methods used by these investigators, it might actually have some relevance - at least in conversation - as the methods they are using were inspired by biology - specifically, self-assembly. Thus invisibility might actually shed some light on self-organisation for some, highlight it even.
