The Evolution of Nanomachinery

csy writes: "Harvard's George Whitesides has a wonderful article on Nanomachinery in this month's issue of Scientific American. He casts doubts on the Drexlerian vision of mechanical assemblers, and argues that biology and chemistry, rather than mechanical engineering point to the answers in the quest for nanomachines."

Memo to nano-bots for my body

[BrentRJones]

I'm so concerned whether they are made of organics or metal (I used to teach chemistry and physics), but I have some work for them to do right away.

Memo to future small robot type guys:

1) Clear out any hardening of the arteries that I have already developed (I'm 50 years old)

2) I hate flossing--could you do that stuff by launching from my mouthwash?

3) About that pain in my lower back? Could you head down there an do a diagnosis? I would hate to let a bone cancer get a headstart. Oh, if there is a tumor or something bad, please take care of that while you're there.

4) Say, Viagra work but it is very expensive. Could a bunch of you tools help my tool--every once and a while? But please give me warning!

5) Hey, I know that this is not so important, but the Q-Tip package says don't use them in the ear canal. Like many others I have been feeling guilty about this for years. Could you guys...you know...that waxy stuff?

6) OK up here in the macro world we have these utilities called McAffee and Norton that look for problems and then if I give the OK, they fix what they can. Well, can we work out something like this, only on your level.

7) Gee. I almost forgot being a diabetic. You guys need to fix that first.

8) And taking that anti-depression medicine Zoloft..could you do something in my brain. BUT PLEASE BE CAREFUL THERE GUYS!

Thanks,
Brent,
Your Commander-in-Chief
