A posting from October mentions Christian Schafmeister’s Feynman prize-winning work on something much like what you’re proposing. He’s come up with a set of 14 amino acid-based building blocks, each of which can form rigid bonds with its neighbors and form predictable and controllable structures. Each building block is about half a nanometer across (for comparison, the diameter of a hydrogen atom is about one tenth of a nanometer, or one angstrom, across, and the largest atoms have a diameter of about three times that). His lab has been able to build various shapes such as rods and crescents out of these monomers.

I would think power systems are a must to scale any manufacturing technology. Quantum dots and fuel cell membranes need parts design accuracies of a few nanometers if not smaller.

Robert Virkus, you are on track. What Dr Drexler and others seem to be saying is that atoms and molecules are not LITERALLY exactly like Lego blocks. Rather, they have complex electrical properties and such. However, it is also true that “Molecular Lego like kits” could be made.

But I have always thought that there must a scale,
somewhat larger than a few tens of nanometers, where prefabricated molecular building blocks could snap together like Legos. What is the simplest system of blocks that could be useful?

It would be really nice if transcripts or recordings of the presentations could be made available…
