Nanoparticle thin films that self-assemble in one minute

A technique whereby self-assembling nanoparticle arrays can form a highly ordered thin film over macroscopic distances in one minute has been designed by scientists. Nanoparticles function as artificial atoms with unique optical, electrical and mechanical properties. If nanoparticles can be induced to self-assemble into complex structures and hierarchical patterns, similar to what nature does with proteins, it would enable mass-production of devices a thousand times smaller those used in today's microtechnology.
