the Dna nanotechnology can be used as a kind of mask from which molecules of various kinds can be deposited in desired positions; or, you can bind the rotaxane solid state on a part of a dna strand and self assemble it in various ways. That’s dna nanotechnology.

Honestly, I really havn’t concluded anything( i just say the foresight blog entry yesterday!); but, here’s a similar concern or idea from some dna-nanotechnology I’ve had. The problem with dna-nanotechnology is it’s in solution and well, you have a lot of atoms and moleculars bumping around whether you want them or not. Solution? Well, after getting the right molecular structure(like a robotic arm), how to control it without the dna-nanotech machine being in solution? Well, have the dna-nano structure on the outside of a bag where the solution of dna messengers and water are kept. So, there’s a bag of some sufficiency where all the dna-nanotechnology goes on, and there’s an outside nanostructure that is being controlled. Well, one can find problems and solutions to those problems from there.

Obviously, the Feynman/Drexler nanotechnology people are excited about this because they can avoid the solution phase chemistry problems. But, they still need to isolate it in a vacuum. That’s why I brought up my idea of isolating a dna-nanomachine on the outside where the solution phase chemistry is isolated. I’m really writing while I’m thinking! Like I said at the start, I just read this yesterday; and, I’m not in a position to try anything(i quit school for rather interesting reasons; i’ve tested things by hanging out on camposs to see how people are; i always end up with cops protecting me at the library; they’re always kicking it with the librarians, can’t believing they have to hang out in the library! I guess I could say discretely, that I have gangster problems! That’s as far as I should really describe it!)

The fact that you’d like to preciselly place a chunk of solid state rotaxane gears/motors suggests stm usage.
One could use these UWDM-1 to fold up graphene(which as I already stated graphene can now be shaped two dimensionally to atomic specification) in desired shapes.
One could attach or use the UWDM-1 as a cam to a protein that can do some certain chemistry function.

Bottom line, one can see the light at the end of the tunnel with UWDM-1!

There’s also been great work in using stm’s to make arbitrary and precise graphene shapes. One way or another, this is exciting for those who would like to see nanomanufacturing happen.
