Nanotechnology will be everywhere this holiday season, and to help people understand the implications of micro-scale engineering, the Project on Emerging Nanotechnology updated its online catalog of nanotech prducts.

The catalog details products from Apple's i Pod Nano, which like many modern electronic devices with flash memory relies on semiconductor manufacturing techniques that require precision below 100 nanometers, to Zellens Fullerene C60 night cream, which uniquely contain Fullerene C60, an extremely powerful anti-oxidant.

Nanotechnology involves the manipulation and manufacture of materials ranging from 1 to 100 nanometers. A nanometer measures one-billionth of a meter.
