Namomachines are very small machines and is also called as nanite.
The dimensions of a nanomachine are measured in nanometers.
In simple words, a nanomachine refers to a system that is made up of tiny component or nanoscale components.
Nanotechnology seeks to develop nanomachines in such a way that they can handle complex tasks independently.
Currently, the development of Nanomachines is in the initial state.
Some nanomachine devices have been tested however, further improvements have to be done.
Mostly, nanomachines are likely t be deployed in the field of medical technology for the purpose of identifying body pathogens and toxins.
They are also used for the purpose of detecting toxic chemicals and the concentration levels of such toxins in the surrounding environment.
The best example of nanomachine is the human body.
Much of the mass of the human body is filled with nanomachines.
If you look at the most basic aspect of the human body, which is the body cell, it in itself is a nanomachine as it is made up of nanoscale components.
If we take Bacteria and Virus as example, there are also versions of nanomachines.
The key feature of nanomachines is that they can be programmed to replicate themselves and they can be brought to work together so that they are always in synch with each other while carrying out their individual functionality.
In the advanced level, a nanomachines can be designed in the form of nanorobos, which can be used to diagnose and detect diseases.
They can be programmed to understand various diseases, how they are caused and also techniques on how they can be eliminated.
If the development of nanomachines reaches a stage wherein they can build themselves up into huge quantities using the process if self assembly and they can be programmed into creating objects, they can be developed into a custom manufacturing system.
