A map of the Americas measuring just a few hundred nanometres across has been created out of meticulously folded strands of DNA, using a new technique for manipulating molecules dubbed "DNA origami." The nanoscale map, which sketches out both North and South America at a staggering 200-trillionths of their actual size, aims to demonstrate the precision and complexity with which DNA can be manipulated using the approach.
According to the map's creator, Paul Rothemund at Caltech in Pasadena, US, DNA origami could prove hugely important for building future nano-devices including molecular machines and quantum computer components.
