Tiny nanomachine successfully completes test drive

Researchers build a one-wheeled vehicle out of DNA rings

The two rings are linked like a chain and can well be recognized. At the centre there is the T7 RNA Polymerase.

Scientists have used nanostructures to construct a tiny machine that constitutes a rotatory motor and can move in a specific direction. The researchers used circular structures from DNA.

Together with colleagues from the USA, scientists from the University of Bonn and the research institute Caesar in Bonn have used nanostructures to construct a tiny machine that constitutes a rotatory motor and can move in a specific direction. The researchers used circular structures from DNA. The results will now be presented in the journal Nature Nanotechnology.
