    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
