A human fetus begins life as a single cell, and then divides to become two cells, then four, then eight and so on. Nanotechnology aims to build in a similar way, constructing objects out of their most basic components. A nanometer is a thousandth of a millionth of a meter. This is about as far down in size as it is feasible to go, because a nanometer is equivalent in size to about three to five atoms. For us, and the things around us in ordinary life, atoms are the ultimate building blocks. If we could get down to that nanometer level, and craft the object with atomic precision, the power of our ability to control the behavior of this object would become immense. The ultimate goal of nanotechnology is to build robots smaller than living cells with the ability to arrange individual atoms into any physically possible pattern with what might be called as nanoscopic precision, the way the nature does. Nanorobots are theoretical nanodevices that will be used for the purpose of maintaining and protecting human body against pathogens. The nano-robots, being smaller than living cells, are equipped with arms able to grasp and manipulate individual atoms, would resemble extremely small unmanned submarines. Nanorobots can theoretically destroy all common diseases of the 2lst century thereby ending much of the pain and suffering. It can also have (alternative, practical uses such as improved mouthwash and cosmetic creams that can expand the commercial market in biomedical engineering. People can envision a future where people can self-diagnose their ?own ailments with the help of nanorobot monitors in their bloodstream.

[...] The cream could be a smart material with smooth-on, peel-off convenience Medical nanodevices could augment the immune system by finding and disabling unwanted bacteria and viruses. When an invader is identified, it can be punctured, letting its contents spill out and ending its effectiveness. If the contents were known to be hazardous by themselves, then the immune machine could hold on to it long enough to dismantle it more completely Devices working in the bloodstream could nibble away at arteriosclerotic deposits, widening the affected blood vessels. [...]


[...] The nano-robot will remain outside the cell while the nano- manipulators will penetrate into targeted or damaged cell thus avoiding any possibility of causing damage to the intracellular skeleton. Figure 4 gives a wonderful simulation of how this process takes place. Figure3. Nanorobot at work Figure 4. Cell surgery Thus these nano-robots when enter into human bloodstream provide cell surgery and extreme life prolongation. A navigational network may be installed in the body to keep track of the whereabouts of the nano-robots, with station keeping navigational elements providing high positional accuracy to all passing nano-robots that interrogate them, wanting to know their location.

Simple everyday illnesses can be cured without ever visiting the physician. Invasive surgery will be replaced by an operation carried out by nano-surgical robots. [...]
