Among the possible nanotechnology applications, nanorobotics constitutes without a doubt one of the most fascinating. The idea is to build machines or robots at a nanoscale. Nanorobotics still remains a very experimental science. However, some promising ideas have already come to fruition.
Recently, the Rice University in the United States, presented the first ever nanocar. It measures barely 4 nanometers long and 3 nanometers wide. Itís comprised of a chassis (a large molecule of the alkyl group) and of 4 wheels (4 p-carbonate molecules)Ö.and it runs! The motor derives its energy from photons from the surrounding environment. According to its builders, this car could serve as a nanomaterial transporter, a cargo vehicle.
Nanorobots could have many applications in medicine. By being inseminated in the body, the nanocarriers could permit the identification of cancerous cells, and penetrate them in order to inject medicinal molecules. Other robots could perform microsurgical operations.
Many other options are being explored.

A nanocar is not a nanobot. So what is a nanobot? Any decision making unit would be much larger than a couple of nanometers. And then one would need energy to make it work. All this would take more space. Looks like nanobots are part of the fantasy world.
