Nanobots get to the heart of the matter
A new breed of nanobots is being designed to assist doctors by going where no surgeon or technology has gone before.
Working at the scale of molecules, these micro-machines are taking their cues from bacteria and the way in which they find their way around the human body. If they are successful, they could bring about a new type of molecular surgery and a different perspective to our own inner space.
The engineers and scientist working on the development of these nanobots -- the size of only a few molecules -- believe they could reach liquid parts of the body difficult or impossible to get to using today's medical practices, precisely delivering drugs to areas such as the eyeball cavity or arteries in the heart.
