In the 1966 sci-fi movie Fantastic Voyage, a submarine and its crew are shrunk to the size of a microbe so they can be injected into the bloodstream of an injured scientist to repair a deadly blood clot in his brain.
For decades, real-life scientists have been fascinated by the technology depicted in the film. “Fantastic Voyage describes the future of nanorobots,” said Gao Wei, 34, a California Institute of Technology professor who co-developed a microrobotic system that can be guided towards specific parts of the digestive tract to treat tumours.
