WHAT IS NANOTECHNOLOGY?AND
WHY IS IT SUCH A BIG IDEA?
Nanotechnology: Small, Different, New
• The nanometer is extremely small.
• At the nanometer scale, materials may behave differently.
• We can harness this new behavior to make new technologies.
Nanometer:Part of The Metric System
kilometer km 1,000 1X103
meter m 1 1X100
millimeter mm 1/1,000 1X10-3
micrometer m 1/1,000,000 1X10-6
nanometer nm 1/1,000,000,000 1X10-9
picometer pm 1/1,000,000,000,000 1X10-12

A Nanometer is Extremely Small.
In the time it takes to read this sentence, your fingernails will have grown approximately one nanometer (1 nm) in length.
