DNA Assembled Nano-Transistors

Posted by CowboyNeal on Friday November 21, 2003 @12:54AM from the self-building-parts dept.

Bob Vila's Hammer writes "In an article at New Scientist, researchers at the Technion-Israel Institute of Technology have harnessed DNA to mold a nano-transister constructed of graphite nanotubes coated in silver and gold. The carbon nanotube assembly when completed is a fully working transistor when voltage is applied. The process is ingenious, using proteins from E. Coli bacterium to bind carbon nanotubes to certain sites on strands of DNA. Then graphite nanotubes coated with antibodies connect to the proteins. Finally, silver ions are added to the solution which chemically bond with the DNA site where the protein is attached. Further refinement of the technique is required before full scale production would be efficient, but this could allow the creation of elaborate self-assembling DNA sculptures and circuitry."

I, for one, welcome our new nano-sized overlords.

since i didnt get first post ::shakes fist::, i have decided to comment. So, where do these "scientists" get this "dna" stuff they speak of?

Great reading. Now, fiction becomes reality.

We're all going to die.
