Bottom up pulls ahead

It looks like the top-down crowd is falling behind in the race for molecular precision. In the linked article, entitled "Chiral KagomeĢ Lattice from Simple Ditopic Molecular Bricks" we see another example of fine atomic precision engineering which mirrors many of the control elements provided in DNA architectures.

The next closest top-down approach which is currently shining involves a UV laser building molecularly precise shapes in type III and V elements. However, that is far less developed than the bottom up approaches.
