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.
