Nanobotics

Nanobotics (or Nanorobotics) is a field of emerging technology that deals with the creation of robots whose components are typically the size of a molecule or nanometer (10^-9 meters). More specifically, nanorobotics refers to nanotechnology, an engineering discipline that designs and builds nanorobots that have movement, processing and transmission characteristics, program execution, etc. Nanomachines are largely in the research and development phase, although some primitive and nanomotor molecular machines have already been tested. One example is a sensor with a switch of about 1.5 nanometers, capable of counting specific molecules in a chemical sample. The first useful applications of nanomachines could take place in the field of medical technology, where they could be used to identify and kill cancer cells. Another potential application is the detection of toxic chemicals as well as the measurement of their concentrations in the environment. Rice University has demonstrated a nano auto (nano car) developed through a chemical process, including Buckminsterfullerene for wheels. It is driven by controlling the temperature of the environment and by positioning a tunnel-effect microscope. Another definition describes nanobot as a machine capable of accurately interacting with nanoscale objects, or the ability to manipulate objects at this obvious scale. The vast majority of nanorobots are able to create copies/duplicates, that is to reproduce, these being called replicators.
