Advance on Nanotech Dip Pen - The Nano Plotter
techtrend writes "In an
article on Eurekalert,
Northwestern chemists report making
the world's smallest plotter, a device capable of drawing multiple lines of molecules -- each line only 15 nanometers or 30 molecules wide -- with such precision that only five nanometers.
They lay down a grid of lines made
of 16-mercaptohexadecanoic acid (MHA). Then
dots of octadecanethiol (ODT) are placed at pre-calculated
positions using the grid for precision positioning.
They plan to use this process to make ultrahigh density arrays
of different organic and biological material and nanostructures.

An excellent area for contribution is design software. Currently there are a number of excellent free molecular modeling packages: MMTK, NAMD, Moldy, NWchem. There are also several excellent display programs: RasMol, VMD, Midas, and my own feeble effort, xyz2rgb. What is still lacking is:
- Software to generate structures painlessly. Two efforts in this area are CavityStuffer by Markus Krummenacker, DiamondCAD by Chris Phoenix and John Michelsen, and some tinkering of mine.
- Some kind of wrapper that makes all this stuff easy to use. There is a commercial package called HyperChem, and the DiamondCAD folks are working on an open-source version called OpenChem.
And if you really want to go wild with this stuff, get a job at Zyvex.WWJD for a Klondike Bar?
