This FAQ suffers a compression fallacy between chemistry (the products you’ve named that actually exist) and nanoscopic robots (which don’t, and we have little to no idea how to get there from here, and the named products of chemistry don’t actually help). Crediting the first as examples of the second is the sort of thing that gets chemists I know punching walls. I suggest taking care not to conflate chemistry with nanoscopic robotics.
