Nanotech Milling Machines
- Here is an article that discusses using AFMs as nanotech milling
machines. I wonder what other group members thought about this idea?
- It sounds very easy but actually it's not. This article talks about
building more stable and repeatable AFM heads. I don't think you're
going to use the AFM like an actual milling machine, i.e. scraping off
bits of material to make a part. The article talks about dip-pen
nanolithography but then if you imagine building up 3D or large 2D
structures you have to explain how the dip pens are kept properly
'inked'; I don't think you get exact molecular order this way and I
think it would be very hard to make the jump using this technique.
However, it is a useful technique in the lab and it can certainly
be further developed and improved.

- I originally read the subject as "Nanotech Killing
Machines", and became a little confused when I read
Anyway, this sounds like a good technique for certain
applications. One of the benefits (and challenges) of
nanotechnology is that the physical properties of
substances change on the nanoscale, and researchers
are trying to build precise nanostructures to take
advantage of this. As has been pointed out, I think,
that doesn't seem possible with this technique.
However it does seem to be useful for creating
extremely small structures where precise atomic
alignment is not necessary.
