  1. Chapter 13: Medical Applications of Nanoscience

  2. Background • Nanomedicine is the monitoring, repair, construction, and control of human biological systems at the molecular level using engineered nanodevices and nanostructures. • Microscopic machines were first hypothesized by Richard Feynman in 1959. • K. Eric Drexler described many applications of these machines in Engines of Creation. • Currently, several university and industrial research groups are developing medical applications for nanotechnology.

  3. Drug Delivery Drug delivery systems: Lipid-based nanoparticles Polymer-based nanoparticles https://www.youtube.com/watch?v=RBjWwlnq3cA

  4. Radiowave Cancer Treatment? https://www.youtube.com/watch?v=svxBvRSSPbw

  5. Tissue Engineering • Nano/micro particles, including living animal cells, bacteria, and colloidal gold (100 nm), can be optically guided and deposited in arbitrarily defined three-dimensional arrays, a process called “laser-guided direct-writing.” Nanofibers (video):

  6. DNA Chips Yeast cells were grown under various conditions; the amount of red or yellow light represents the level of RNA produced from the DNA in that gene, under those conditions. https://www.youtube.com/watch?v=UgL1Pq2sk3M

  7. Respirocytes: A Mechanical Artifical Red Blood Cell https://www.youtube.com/watch?v=WzGKlVZtQs0 • Bloodborne spherical 1-micron diamondoid 1000-atm pressure vessel • Active pumping powered by endogenous serum glucose • Able to deliver 236 times more oxygen to the tissues per unit volume than natural red cells and to manage carbonic acidity http://www.foresight.org/Nanomedicine/Respirocytes.html

  8. Future Posiblities: Oxygen Selective Pump

  9. Fixing Damaged Biosystems https://www.youtube.com/watch?v=Q8tAj8A4pc0
