Buckminsterfullerenes or buckyballs are typically spherical and they are composed of 60 carbon atoms with a cage-like structure. C60 is made of 12 pentagonal and 20 hexagonal rings. As you already know, you can buy carbon 60 with excellent quality in our company. The spherical shape of fullerene C60 could bring you to mind the shape of a soccer ball. By the way, did you know that fullerene is the most symmetrical structure in the world? We can find three kinds of rotation axes.
C60 fullerene is a perfect candidate for biomedical engineering due to its desirable properties. As you can see above, fullerenes have really interesting solubility in different solutions, the most compounds are aromatic. The most developing area in biomedical engineering using C60 is undoubtedly cancer research which is undeniable so much important in present-day medicine. And what makes C60 fullerene so promising in this kind of research? Fullerene C60 could be occluded by cancer cells by using various functional groups. After the absorption fullerene could turn oxygen inside of a cancer cell (in presence of the light radiation) to reactive oxygen radicals which evoke apoptosis (the cell will literally commit suicide because reactive oxygen will be devastating all the important biomolecules in the cell and the cell simply cannot survive this demolition). This process is called photochemotherapy and it can be a good alternative to radiation therapy. The other biochemical applications include the design of various agents used for example in MRI (Magnetic Resonance Imaging), X-Ray imaging, drug and gene delivery (mainly hydrophobic drugs) and so on. As you can see, fullerenes are showing really good biocompatibility.
Fullerenes C60 could also be used as electrocatalysts for example in fuel cells when fuel is oxidized at an anode and oxygen is reduced at a cathode. With a high level of pollution from fossil fuels in our world is generally a great effort to find an alternative to fossil fuels. Fuel cells could be that alternative because they convert chemical energy to electrical energy. They could directly use alcohol such as methanol and ethanol.
Fullerenes can be used for gas storage due to their unique structure. Other carbon structures are hydrogenated and dehydrogenated irreversibly. But fullerenes overcome this barrier. When C60 fullerene is hydrogenated it changes the color according to the sum of added hydrogen.
Another application of fullerenes can be found in a composite coatings area of research. If we want to enhance the properties of a common used coating agent, the best way to do it is by adding nanofillers.
Fullerenes are also known as excellent antioxidants. They can react at a high rate with many radicals and behave as some kind of shield in front of dangerous radicals. They even earned the nickname " the free radical sponge". They are able to neutralize around 30 radicals per one fullerene molecule. That is so amazing!
It can be a huge surprise but fullerenes can be also used in cosmetology. There are creams containing several fullerene derivatives. For example, polyethylene glycol-modified fullerene C60 is commonly used. Because of fullerenes antioxidant capabilities, fullerene can be also used as a derivative of vitamin C (ascorbic acid) or vitamin E (tocopherol) to prevent lipid peroxidation due to the effect of radicals.
We all know that diamonds are made from carbon so it should not be a big surprise if we could use fullerenes as precursors to create diamond.
Last but not least, fullerenes can be used for the strengthening of metals. Fullerenes can use the advantage of small size and excellent reactivity to interact with a number of metals and create a stronger and hardener material than the metal itself. This has a huge application in aerospace technologies.
