(Popular Mechanics) – For decades, scientists have been dreaming of one day creating tiny nanobots that can work at the microscopic scale, building things one molecule at a time or purifying our bloodstreams. While we might actually enjoy the work of those nanobots someday, for now they’re still in the realm of science fiction. But a group of Caltech researchers are working to change that, by building a prototype nanobot made of DNA.
