Construction of the robot: Nanorobots are made out of parts from 1 to 100 nanometers, mainly composed of carbon in the diamond/fullerene nanocomposites forms because of the strength and chemical inertness of these forms. The best coating to avoid the immune system attacking them is a passive diamond coating.

History: No artificial non-biological nanobots have been made, so they are still hypothetical. However, they were envisioned as early as the 1860’s. James Clerk Maxwell proposed a thought experiment in which a tiny entity dubbed “Maxwell’s Demon” would be able to handle individual molecules. Richard Adolf Zsigmondy published a book in 1914 about using an ultramicroscope and the dark field method to see particles like gold sols with size 10nm an less.

Who is using it? Anybody that does work that requires precision interactions with nanoscale objects. Doctors may be able to use it to help treat patients more efficiently, and there are other professionals that might be able to use it. Nanorobots involve a multidisciplinary approach between cell biology, biochemistry, and biomaterials engineering, and the potential applications of nanobots are almost unending.
What are they using it for? The main purpose will be maintaining and protecting the human body against pathogens. They can cure skin diseases; be used in mouthwash to identify and destroy pathogenic bacteria as well as lifting particles of food, plaque, or tartar off of teeth to wash them away; augment the immune system to find and disable unwanted bacteria and viruses; and also getting rid of arteriosclerotic deposits in the bloodstream to widen the affected blood vessels.

“Lab-on-a-chip (LOC) devices have become familiar in recent years to the general public. Nanotechnology is enabling new generations of LOCs to become highly specific for the detection of viruses, bacteria and a wide range of metabolic functions using tiny quantities of analyte and returning a wide range of results extremely rapidly. New generations of biosensors, likewise, have been developed that are able to detect minute changes in physiological state or the presence of pathological agents down to single molecules or viral/bacterial entities. The combination of both will facilitate the development of new generations of medical devices including very fast and accurate in vitro diagnostics and implantable in vivo diagnostic devices that can operate in real time, perhaps transmitting signals back to other devices like implantable cardiac devices or insulin pumps.”—Institute of Nanotechnology (08 December 2009), NANO magazine (Issue 5)

How does it work?
What does the future look like? The future is everything for nanotechnology. Since nothing has been built, there are many opportunities for the scientists working with them to develop nanobots with a variety of different uses. They have potential usage in medicine, chemistry, energy, information and communication, heavy industry, and even consumer goods.
