This is good teaching information and good use of keywording for sudents for a discission in class. This is not my subject, although as a school teacher week at time look out for intresting useful material forteaching for each other at school.

Thank you for the useful post on Carbon Nanotube Transistors through DNA Origami.

@ John — Yes, the sizes are very different, and this limits the scope of any proper comparison. There is, however, a fundamental similarity (both do nanoscale fabrication) paired with a great contrast in the nature of the equipment. Comparing these illustrates something important.

[...] I noted in a recent post on self-assembled nanoelectronics (“Carbon Nanotube Transistors through DNA Origami”), carbon nanotubes (CNTs) hold promise for self-assembled nanomechanical systems, too: They are [...]

It isn’t fair to compare costs with industrial fabs. That is apples and oranges.

Between the work I am seeing on Graphene, and the work being done on DNA and nanotubes, it’s seeming possible that we’ll see a complete nano electronic circuit produced soon. Scaling seems to be progressing quite well.

It’s possible we’ll see the first nanoscale processors this decade, maybe even sooner.

“…can make the tubes soluble and.” and what??? Don’t leave us hanging! I’m guessing “and able to bind to each other in precisely specified patterns.”

Seeing the result may be hard. But combine this transistor-building technique with IBM’s technique for fastening down DNA macrostructures, oriented, on lithographed spots, and you may be able to simply run JTAG tests. Eventually.
