Nanotechnology is the study and use of materials with 1 dimension less than 100 nanometers (nm) 1 mm m 1 micron m Bacteria “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 to President Clinton for Science and Technology Global Nano-enabled products: 2006: $60 billion 2014: $2.6 trillion or ~ 15% of total global manufactured goods 1 nanometer m 1 Sugar Molecule

In the time it takes to read this sentence, your fingernails will have grown 1 nm. HOW SMALL IS NANO?

How big an area could you paint if you could make it only 1 nm thick? Coverage with normal use: sq. ft 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 are 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: to m –Examples: aerosols, smoke, milk, mayonnaise, paint.
