Most people are aware of c60 fullerene, the miracle material used in contact lenses and other forms of medical equipment. The wonder material was developed by NASA as part of their effort to create a micro-structure for a new generation of lenses. The material had many benefits over other materials that had been previously used.
The material was highly lightweight and it could be manufactured into thin sheets that provided resistance to abrasion and compression. These thin sheets made it easy to coat the inside of the lens with a liquid binder so that the contact lenses would stay together and would not fall out. These properties made c60 one of the best materials available for contact lenses.
When looking at the material, it is easy to see how NASA developed c60. The material is mostly composed of two different compounds called dimethoxy and carboxylic acid. The two covalent compounds react with oxygen to form a compound called dimethoxy oxygen (DMO). This substance has an electrostatic charge that can only happen when the hydrogen atoms are in an excited state.
Once the DMO molecules are in an excited state they form a diamond shape. The shape makes it easier to attach the carbon dioxide atoms to the oxygen gas molecules. The DMO layer also has a negative charge which repels any other metal ions trying to come to the surface. The combination of these two properties makes it very difficult for anything to attach to or steal the electrons that make up the DMO layer. As a result this makes it very difficult for oxygen to escape from the lens.
The main place where c60 fullerene is used in the medical field is in contact lenses because of its unique properties. Since the fullerene molecules are so tiny they don’t allow water to pass through them. Water gets evicted from the lens before it has a chance to get into the cornea of the eye. However, the contact lenses are designed in such a way that the evaporation process allows some water to leak out into the air. Because of this ability of the c60 contact lens to prevent water from leaking out it is often used in surgical operations involving open wounds as well as being a major part of cosmetic dentistry as it can provide a clear and painless smile.
When looking at the applications of c60 fullerene it is important to remember that the material is not as hard as you might think. While it is difficult to break the material it is as hard to keep it from coming apart. One of the biggest problems with this particular type of material is that if a person tries to wear it too tight the oxygen molecules inside the c60 can get squeezed. This causes a chemical reaction that creates a gas that is toxic to the person wearing the contacts.
