The term ‘Nano’ means 1,000 millionth of a unit, so the term ‘Nanometer’ means one thousand millionth of a meter. Carbon Nanotubes were first discovered in the year 1991. These thin, long cylinders of carbon are shaped as hexagons. They are known as the strongest and hardest bonds that have been found in chemistry history, and are even stronger than the bonds that are found in diamonds. What makes Carbon Nanotubes so outstanding is their variety of structural, thermal and electronic properties. Through nanotechnology, carbon nanotubes have been developed more and more which helps construct devices and circuits from a single type of atom and molecule.
Carbon Nanotubes have a long list of extraordinary and useful physical properties, and the applications of carbon nanotubes are endless. The bonds are more than 300 times stronger than steel and at the same time are lighter and more durable. They have the capability of handling what cannot be handled by any other metal found on earth.
Due to discoveries of the many uses and applications of Carbon Nanotubes, it is possible that they will be used as an alternative energy source in the near future.
Uses and Applications of Carbon Nanotubes:
By using DNA strands or protein receptors that can detect traces of chemicals, it is possible to modify carbon nanotubes. It can be used to identify a long list of things. The applications for these carbon nanotubes include searching for bombs, detecting toxins in water or air, and can even be used to test for cancers.
Another application for carbon nanotubes is the use in artificial muscles. They suit this use as they can still keep their shape after being compressed thousands of times.
Amazingly, carbon nanotubes can be modified to become compatible with any part of the human body. Because of this, nanotubes are used restructuring damaged bones in the body.
