A machine with the size measurable with the scale of 10-9 meters which can be operated as per our instruction is given by the programmed systems. This size can be imagined when we can compare the red blood cell in the human body a size approximately about 5 nanometers it means 5 X 10-9 meters. If this molecule becomes our target and for treatment of red blood sized molecule we use less sized equipment and control it and operate in such a fashion which give our desired product or results than this concept comes under the study of nanotechnology.
Nanobots are such small pieces of machine or robot which can be programmed and monitored so that they stay in the human body and repair the system and make it work more efficiently, for example, to prevent ageing process the nanobots can adjust the fat and muscles under our skin. They work as warriors and kill all the bacteria and virus like even HIV virus to protect use from causing sickness. They take less power to work and obtain it within our body, of course, we are in the preliminary stage but soon this will be our new world of technology where human life will completely change.
Nanobots will be used to make new drug molecules and even function as a small reactor in the human body which can produce insulin, a permanent cure for a diabetes person. To control your body weight they even burn out your fat and make you appear as you like.
Carbon nanotubes are used mainly in designing of all nanomaterials and devices along with other metals of the same size, with the help nanotweezers, all the parts are assembled and shaped as per the required design.
