New Scientist: Nanoscale robots have been created from DNA and injected into living cockroaches, according to a recent paper published in Nature Nanotechnology. The nanobots travel around the insects’ bodies and act like tiny computers to diagnose and treat diseases. Made from strands of folded-up DNA, they seek out diseased cells, where they then unfold on contact to dispense a dose of drugs. If the nanobots’ diagnostic power can be scaled up sufficiently and their stability enhanced to survive in humans, they could find wide use in a number of environmental and health applications, such as the treatment of various cancers.
