Innerspace photographers come to the aid of surgeons and this is not science fiction anymore. The new photographer is a tiny robot in your blood stream relaying images to the surgeon. Scientists at the Monash University of Australia have come up with a motorised robot small enough to be injected into the human bloodstream.
Soon, the remote controlled bot could carry sensor equipment for observation work, relaying images back to the surgeon. or, it could become a tiny surgeon, cutting away blood clots, reaming out clogged arteries or repairing damaged tissue. The microbot measures just a quarter of a millimetre, or “two or three human hairs wide,” says lead scientist James Friend from the Nanophysics laboratory at Monash University, Australia.
