Six of one and half a dozen of the other: A cyclic hexamer of six gold nanoparticles was sequentially and selectively self-assembled by labeling each particle (red sphere) with a DNA-containing molecule (colored block), which serves to dictate its ultimate location within the final construct. This method may be used to construct any discrete well-defined pattern of nanoparticles.
