An Introduction to Nanotechnology




One nanometer = one billionth of a meter (1 nm = 10-9 m)

The width of DNA is about 2nm

Powers of Ten


Sort-of nano-products:

Inside the iPod Nano are memory chips from Samsung and Toshiba. Samsung, the biggest producer of NAND and DRAM flash memory chips in the world, uses semiconductor manufacturing methods with precision below 100 nanometers. This precision, in part, is what enables the iPod Nano's 4 GB NAND flash memory.

Totally bogus, just using "nano" to get attention:
