Nanotechnology is the study and use of materials with 1 dimension less than 100 nanometers (nm) “If I were asked for an area of science and engineering that will most likely produce the breakthroughs of tomorrow, I would point to nanoscale science and engineering. ” - Neal Lane, Former NSF Director and Assistant Clinton for Science and Technology Bacteria 1 Sugar Molecule 1 mm 10 -3 m 1 micron 10 -6 m 1 nanometer 10 -9 m to President Global Nano-enabled products: 2006: $60 billion 2014: $2. 6 trillion or ~ 15% of total global manufactured goods www. nanoproject. org

HOW SMALL IS NANO? In the time it takes to read this sentence, your fingernails will have grown 1 nm. http: //www. mrsec. wisc. edu/Edetc/curriculum/index. html

HOW SMALL IS NANO? Coverage with normal use: 250 -400 sq. ft How big an area could you paint if you could make it only 1 nm thick? About 1. 5 square miles! The average thickness of wall paint is about 100, 000 times thicker than a nm

Nanotechnology • The art and science of building stuff that does stuff at the nanometer scale • The ultimate nanotechnology builds at the ultimate level of finesse one atom at a time, and does it with molecular perfection • It holds the answer, to the extent there answers, to most of our most pressing material needs --- Richard E. Smalley 1996 Nobel Laureate in Chemistry University Professor, Rice University From MIT Forum Jan 22, 2003

Nanotechnology Includes • Development of completely new material or technique – Single Walled Carbon Nanotubes – Bottom-up Assembly • New processing of an existing material – Zinc Oxide For Sunscreen – Old Way: Big white stripe on your nose – Nano Way: Clear sunscreen • New Way of Looking at Established Fields Like Colloids – Mixtures of two or more substances in which one phase is suspended as a large number of very small particles in a second phase. – Size scale: 10 -9 to 10 -6 m – Examples: aerosols, smoke, milk, mayonnaise, paint.
