Study Notes
Fullerenes
- A crystalline allotrope of carbon
- A hollow ball of carbon atoms
- Most stable fullerene form is C60
- Consists of 20 hexagonal phases and 12 pentagonal phases with 60 vertices
- Each carbon atom linked to 3 other carbon atoms
- Average carbon-carbon bond length is 1.44 angstroms
- Potential uses include:
- Conductors
- Synthesis of nanotubes and nanowires
- Adsorbent for gases
- Lubricants
- Antioxidants in cosmetics
- Catalysts
Buckyballs in Medicine
- Potential applications in medical imaging
- Metal atoms can be trapped inside buckyballs
- Buckyballs containing gadolinium can be used for medical imaging and flushed out after use
- Can be used to deliver drugs directly to infected regions of the body
- Buckyballs can be modified to release drugs only in areas with specific pH levels
- Small size of buckyballs allows them to move easily within the body
Applications of Buckyballs
- Stronger polymers are being developed using buckyballs by DuPont and Exxon
- Antioxidant type drugs under development or testing:
- Anti-aging or anti-wrinkle creams by Mitsubishi
- Buckyball-based drug to fight arteriosclerosis by Taiwan University
- Burn creams and an HIV drug by C Sixty
