An Angstrom is 1/10 of a nanometer. A silicon crystal has a nucleus to nucleus spacing of 5 Angstroms. Or 0.5nm.

So an "atomic layer" is about 0.5nm.
40 atomic layers ~ 20nm.

Thanks Spuck. Walks away, head spinning, at the amazing depth of knowledge on this board.

Maybe... the writers of all these links don't sound like the scientists/technicians that are actually doing this amazing shit, and the differences are in the virus' eyelash range.
The idea of making anything, any size, and knowing exactly how many atoms it contains... paging Gene Roddenberry.
