Programmable disorder - Stochastic algorithms at the molecular scale

In contrast to biology, engineering seldom takes advantage of the power of randomness for fabricating complex structures. Now, a group scientists has demonstrated that randomness in molecular self-assembly can be combined with deterministic rules to produce complex nanostructures out of DNA.

Hybrid approach predicts and confirms structure of complex metal nanoparticles

A combined theoretical and experimental approach has allowed researchers to predict and verify the full structure of a monolayer-coated molecular metal nanoparticle. The methodology was tested on silver-thiolate nanoparticles, expanding on earlier knowledge about gold nanoparticles, and is expected to be applicable to a broad range of sizes of nanoparticles made of different elements.
