Nanosecrets of Everyday Things
prostoalex writes "A recent issue of Berkeley Lab Research Review discusses the nanosecrets of everyday things. The article talks about common everyday applications of nanotechnology advances, as well as takes a look at tools used to manipulate itty-bitty widgets."
You are confusing nanotechnology with positional assembly
Assembling things one atom at a time is one way to accomplish nanotechnology, but it would be incorrect to assume it is the only way.
If you're feeling a little too paranoid, check out this link, where the threat of gray (or black) goo is analyzed a bit. It's not as bad as you think; blue goo should be able to protect us ;)
(Quick reference:
gray goo = accidentally released nanobots that eat everything
black goo = deliberately released nanobots that eat everything
blue goo = counter-nanobots that prevent gray/black goo from eating everything)
