Nano-robotics is the emerging field of building tiny machines, whose dimensions are measured in nanometers. A nanometer is a billionth of a metre, or to put it another way a millionth of a millimetre. Generally nano machines are still only theoretical. With current technology we cannot as yet make these machines. Even the physics and chemistry of machines of this size is still being studied. Though rapid gains are being made and these may soon prove fruitful. Most proposed applications of nano-robots are medical.
People have suggested that nano robots could enter the body and work from the inside to repair damaged parts such as the heart or deal with disease. Nothing like this has yet been produced, but this still remains one of the most likely products of nanotechnology. With huge amounts of money being spent on research and development, other approaches involve combining nano robots with naturally occurring bacteria. In summary, there is a lot of potential for this technology. How it may change our lives in the next ten, twenty or thirty years will be exciting to watch.
