3. Introduction to Nanotechnology By Randy Applegate At the RET sponsored by UVA and the Center for Diversity In Engineering

4. What is Nanotechnology the study of the controlling of matter on an atomic and molecular scale. Generally nanotechnology deals with structures sized between 1 to 100 nanometer in at least one dimension, and involves developing or modifying materials or devices within that size. atomicmolecularnanometer atomicmolecularnanometer

5. Nanotechnology is already making today’s products: Lighter Lighter Stronger Stronger Faster Faster Smaller Smaller More Durable More Durable

6. How small is Nano - small? Units in nanometers (µm)
