LONDON, England (CNN) -- 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. (Full story)

In what areas of science and technology do you think nanotechnology will provide the greatest advances?

Nanotechnology has the potential to provide advances in both medical and environmental sciences with their ability to search the body for different diseases, tumors and organ disorders in a natural state. One of the best uses could perhaps be for nanobots to seek out breaks or holes in components. They could then heat themselves up from the inside out, melting without damaging anything in their immediate area. The melted liquid would in turn fix the damage.
