  1. carbon nanotubes catch cancer By: John Rawls

  2. Facts About Cancer • There are over 100 types of Cancer • Over 7 million deaths a year (2004) • Makes up over 13% of the world’s deaths each year • The disease can affect all parts of the body

  3. Common Types • The top five in Men: • Lung • Stomach • Liver • Colorectal • Oesophagus • The top five in Women: • Breast • Lung • Stomach • Colorectal • Cervical

  4. How do you know? • Tests are called screenings • Different types: • Physical Exam • Laboratory Tests • Imagining Procedures • Genetic Tests • Finding Cancer early can save lives

  5. Laboratory Tests • Circulating tumor cells • About 90% of cancer related deaths are not due to the original site of the cancer • Important to find these traveling cancerous cells • Usually only several cells per 1-milliliter sample of blood, which can contain tens of billions of normal blood cells

  6. Previous Method • Blood is taken from the patient • Passed over thousands of silicon “posts” • Antibodies coat the outside of silicon • Not too efficient given the amount of cells • Scientists look for more efficient strategy

  7. Nanotubes • http://www.youtube.com/watch?v=zQAK4xxPGfM • Understanding of Carbon Nanotubes

  8. Carbon Nanotubes • About 8 times more efficient • 10 billion to 100 billion carbon nanotubes per square centimeter • Less than 1% carbon and 99% air • Easy to flow through

  9. Pictures

  10. The Future • Can change the Geometry • Tumor cells, about a micron in diameter, down to viruses, which are only 40 nm • Possibly able to test for HIV • Leads are forming for handheld devices • Lead to more availability • Better diagnostics • Location?
