Introduction to Nanotechnology

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.

Nanotechnology

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

How small is Nano - small?

Units in nanometers (µm)

Compared to Human Hair

A Human Hair is about 100,000µm wide
