The view that nanotechnology will lead to tiny robotic submarines navigating our bloodstream is ubiquitous but there is an almost surreal gap between what the technology is believed to promise and what it actually delivers. Vehicular utopias, such as Jules Verne’s voyage under the sea, and dream machines, such as nanorobots, have tended to fill this surreal gap and have had an immediate and long lasting hold on public imagination. They continuously serve to sciencefictionalise science fact and blur the boundaries between cultural visions and scientific reality.
