Nanobots are robots that are microscopic in nature, measured largely on the scale of nanometers. They are currently in the research and development phase, but on realization they are expected to do specific tasks at the atomic, molecular and cellular level and help in bringing about many breakthroughs, especially in medical science.
Nanobots are also known as nanomachines, nanorobots, nanomites, nanites or nanoids.
Nanobots can be considered to be machine version of a bacteria or virus. They can be biological or synthetic, but are adapted to perform preprogrammed tasks at the atomic level. They are expected to be autonomous in nature and powered by a small cell or battery, or even solar cells. The whole idea behind nanobots is in having a device which can interact at the nano scale and help in understanding or manipulating structures at the nanoscale level. In the development of nanobots, nanoassembly and nanomanipulation have important roles.
Considering their potential, nanobots find their first and most prominent applications in medical science. Applications such as closing open wounds, rebuilding ruptured arteries and veins and traversing through the body for diagnoses are some important realizations. They are expected to aid in research related to cancer, AIDS and other major diseases as well as in helping brain, heart and diabetes research. Other applications where nanobots can potentially be of use are in aerospace, security, defense, electronics and environmental protection.
