This is Ned Seeman again, and now we're going to go on to the second part of this talk. And here we're going to discuss organizing other materials with DNA, not just DNA by itself. And we're also gonna talk about dynamic aspects of structural DNA nanotechnology, namely machines that change their states, and walkers, and the combination of these things even to make a nanoscale assembly line within the structure.

On the next slide, we're gonna show how we can organize other chemical species.

So the first thing that I'll talk about is organizing 5nm and 100nm gold nanoparticles in two dimensions, work done by Jiwen Zheng and Pam Constantinou from my lab, Christine Micheel and Paul Alivisatos from Berkeley, and Rick Kiehl when he was at Minnesota.

So we can see that we have a tensegrity triangle where, now it's bigger than it was before, each of the edges is the DX molecule, rather than just a single duplex. And these guys are about eight turns long.

And we can make a two-dimensional array just by using two of the sticky ends either with one tile or two tiles, just like we did in three-dimensions.
