Graphene is a single layer of graphite with very strong covalent bonds. It can be used to make different shapes which we call fullerenes. As each atom donates one electron to a pool of delocalised electrons, graphene can also conduct electricity.
Graphene is completely natural but scientists make strong thin sheets of it to form tubes, pentagons and hexagons (which are made into spheres)
Scientists can form the spheres of fullerenes around other molecules such as drugs, so that it acts like a cage and can be used to deliver the drugs to certain areas of the body.
Fullerenes have a large surface area to volume ratio so they can be used to make industrial catalysts.
The tubes known as 'nanotubes' can be used in nanotechnology and electronics because they can conduct electricity.
Fullerenes are also used to strengthen materials as they have a very high length:diameter ratio, which adds a lot of strength without weight.

We call technology that uses these tiny structures nanotechnology which is now used in loads of industries such as medicine, batteries, fashion and even food.
