Scientist Designs Nanoparticle Optics That Self-Assemble
Posted by Kit Eaton at 12:10 AM on November 6, 2008
Nanoparticles that self-assemble into complex optical structures sounds like an early ingredient in a future Robot Uprising recipe, but the science team at University of California, Berkeley thinks they'll be useful for nicely tame things. The self-assembly of the nanoparticle silver crystals can be controlled to produce different nano "devices" and it's a a neat way of putting together nanotech that is more typically produced top-down by lithography. The devices can be as diverse as colour-changing paint, optical computer elements, and ultrasensitive chemical sensors.
Most interesting, perhaps, is the possibility of using the nanoparticles to construct metamaterials. In this guise they may find use as "invisibility cloaks"... which are currently nearly impossible to manufacture, and that's where the self-assembly part comes in.
The octahedral silver nanoparticles are produced in solution, and are relatively large scale, which lends them potentially better optical properties than competing nanoparticle inventions. [TechnologyReview]

@lifetraveler: I'm pretty sure the properties of mimetic poly alloys is beyond our capacity at the moment. Whew!

Can I tell it to turn into a Nikon D-90?

The first thing this should be applied to is 'self-repairing while in use' condoms cuz ya know, accidents happen....

Or theoretically perfect lenses for cameras?

I vote that the Goo is here as well. Just wait until it self-assembles into an oxygen-eating ultra catalyzer that turns sunlight into CO.

@1roll20s:
just as long as they remain theoretically perfect and not actually perfect.

@blackmage439: I thought the same thing, although they're just particles and not intelligent in any way. Besides, if they were replicators, they wouldn't destroy their creators anyway, they just wouldn't protect us from alien invasion.

So since these are nanoparticle optics that can morphe, and self assemble with ai, can they display actual images of the environment surrounding the nanotechnology materials, like a Predator in Predator vs. Alien 2 etc...? Hmmm, sounds spooky, lol.

But can these optics display and bend UV rays with out glowing on a nanoparticle shape memory quantum display on a redeveloped nano-polymer that can rebuild itself and have other measures with ai?
