Single silicon atoms were pulled out from a silicon crystal by purely mechanical force. Christan Shafmeister designed something like a protein, except it doesn’t have to fold up to gain its structure. It’s rigid as it’s built. Paul Rothemund invented a way of building shapes out of DNA that is extremely simple, flexible and extensible. Several people, including Merkle, have continued to study mechanically guided chemistry. Nadrian Seeman created, designed and built a machine that’s built of DNA, programmed by DNA, and builds DNA. It cannot build itself, but it can build one of four strands, depending on how it’s programmed. [...] [...] I want to mention just a couple of things that have happened in the last few years.
