[extropy-chat] DNA Makes Nanotube Transistors

[Jeff Davis]

Extropes,

A long --in a pre-singularity pre-frenzy sort of way--
time coming, but no surprise.  Re all the glam talk of
DNA, carbon nanotubes, and "self-assembly", the Geek
chorus (us) is at risk of becoming all jaded and
ennui-ed out.  So buck up, and have a Merry Christmas.
 It ain't no Santa Claus machine,... but it's a step,
a real step. Not just vaporware.

Tis the season.  Remember the people you care about,
and those who care about you.

Best, Jeff Davis

The researchers attached DNA strands to carbon
nanotubes and complementary strands to gold electrodes
that were anchored to a silicon surface. The
electrodes were prepared using standard chip-making
techniques. They mixed a liquid containing the
DNA-coated nanotubes with the silicon, and the
complementary DNA strands combined, placing the
nanotubes across pairs of electrodes.
