Nanorobots

Nanorobots (nanobots, nanoids, nanites or nanomites)

They are ranging in size from 0.1-10 micrometers. Nanorobots are theoretical microscopic devices measured on the scale of nanometers (1nm equals one millionth of 1 millimeter). Macroscale robots or microrobots are considered as nanorobots.

Nanomachines are used in Medical technology to identify cancer cells and destroy them. Another potential application is the detection of toxic chemicals and the measurement of their concentrations, in the environment. The traditional treatment of radiation kills cancer cells and healthy human cells. They cause hair loss, fatigue, nausea and depression.

Nanomedicine's nanorobots are so tiny that they can easily traverse the human. A network of special stationary nanorobots positioned throughout the body. A doctor monitor a patient's progress and change the instructions of the nanorobots in vivo to progress to another stage of healing. When the task is completed, the nanorobots would be flushed from the body.
Nanorobots will possess two-way communication and respond to acoustic signals. They will be able to receive power or even re-programming instructions from an external source via sound waves.
