Nanotechnology is technology that has parts operating in the range of between 1 nm and 100 nm, so actually this technology is nanotechnology—as is much of the rest of biotechnology.
You’re right that the usefulness of non-biotech based nanotechnology (what people typically think of as nanotechnology) hasn’t been used much—that’s largely due to it being a nascent area. I expect that to change over the coming decades as the technology improves. It might not, though, as biotech based nanotechnology might stay in the lead.
