Leaf-spring nano-engine as simulated in oxDNA model. [Image: The researchers] An international team of scientists has recently developed a novel type of nano-engine made of DNA. It is driven by a clever mechanism that can perform pulsing movements. The researchers are now planning to fit it with a coupling and install it as a drive in complex nanomachines. Their results were published today in the journal Nature Nanotechnology.
Yeah and if you do it enough times, the usb drives might assemble into grey goo.
Here’s the summary for the wikipedia article you mentioned in your comment:
Gray goo (also spelled as grey goo) is a hypothetical global catastrophic scenario involving molecular nanotechnology in which out-of-control self-replicating machines consume all biomass (and perhaps also everything else) on Earth while building many more of themselves, a scenario that has been called ecophagy (the literal consumption of the ecosystem). The original idea assumed machines were designed to have this capability, while popularizations have assumed that machines might somehow gain this capability by accident. Self-replicating machines of the macroscopic variety were originally described by mathematician John von Neumann, and are sometimes referred to as von Neumann machines or clanking replicators. The term gray goo was coined by nanotechnology pioneer K. Eric Drexler in his 1986 book Engines of Creation.
