The chemical and physical properties of fullerenes have been a hot topic in the field of research and development, and are likely to continue to be for a long time. One possible use of fullerenes is in armor design. Fullerenes would be ideal for this, as they are as hard or harder than diamond. Fullerenes were under study for potential medicinal use: binding specific antibiotics to the structure to target resistant bacteria and even target certain cancer cells such as melanoma. In the field of nanotechnology, heat resistance and superconductivity are some of the more heavily studied properties.
