Chris - the line, "Nanoscale technology does not build complete products, only components" is disingenious, at best, given the history of speculation, conceptualization, etc done elsewhere on this same web page. Perhaps "Current nanoscale technology..." might be a viable option?

Otherwise, a very fair, evenhanded response. Well written.


Chris Phoenix, CRN

Nanoscale technology is inherently limited; it can't build anything with lots of complexity, because it doesn't include a general-purpose manufacturing system. I expect this to remain true for the foreseeable future. So I don't expect nanoscale technology to move beyond the component stage. Even MEMS need to be packaged.


John B

OK, so MEMS need to be packaged. Fine and good - what's wrong with packaging them in diamondoid?

Additionally, were you not talking about building an electric car out of nanoassembled carbon materials on this very site? Using high-pressure water for bulk & kinetic dissipation, but that's added after the fact? What would be the limiting factor in building such a device, as compared to building the parts individually and using human/robot labor to put the parts together? Simply a larger nanofactory 'surface'? A more complex program?

Considering that nanotech *can* self-replicate with 'n' pieces each approximating-but-less-than the complexity of a Pentium (per Toth-Fejel's study), how complex can we expect nanotech to be able to make things? It's repetitive, but so're battery cells, wires, etc.

Or am I utterly missing something here, something I'm apparently good at. *wry grin*


Chris Phoenix, CRN

John, I use the term "nanoscale technology" to mean "the stuff the NNI is working on--using big equipment to build small low-information nanoproducts." So nanoscale technology is a separate category from molecular manufacturing/MNT.


John B

Fair enough.

Suggestion/request - please put together a dictionary of terms you're using somewhere for people to reference. Either here or wisenano, or wherever else. Otherwise it's kind of a dirty trick, switching terms with no clear definition.


Mike Treder, CRN

There is an online glossary at Nanotechnology Now that we assisted in compiling. It doesn't have "nanoscale technology" in it, and some of the definitions keep evolving so it may not always be up to date -- but it's a start.

John B

Thanks, Mike. Any plans to update or suppliment it?


Rocky Rawstern

John: we're always adding new terms, and updating those that need it.

Please let me know if you have any suggestions.

Can anyone please advice on the use of nano technology in disinfectant products? Thank you.
