In January 1999, Professor Seeman’s lab announced the development of a machine constructed from DNA molecules, which had two rigid arms that could be rotated from fixed positions by adding a chemical to the solution. However, the chemical affected all molecules within a structure uniformly.

A team of New York University researchers has taken a major step in building a more robust, controllable machine from DNA, the genetic material of all living organisms. Constructed from synthetic DNA molecules, the device improves upon previously developed nano-scale DNA devices because it allows for better-controlled movement within larger DNA constructs. The researchers say that the new device may help build the foundation for the development of sophisticated machines at a molecular scale, ultimately evolving to the development of nano-robots that might some day build new molecules, computer circuits or fight infectious diseases.

The research team was led by NYU chemistry professor Nadrian C. Seeman. Their findings are reported in the January 3, 2002 issue of Nature. Professor Seeman said, "DNA devices can provide models for the development of nanorobotic applications -- provided the individual devices can be manipulated separately. Our findings have taken the first definitive step in localizing movement within molecular scale DNA machines, introducing independence of movement within a wider structure."
