Nanotechnology is the co ntrolled manipulation of matter on an atomic and molecula r scale to produce quantum mechanical effects that are not present in larger matter. One nanometer (nm) is one billionth, 0. or 10 −9, of a meter.To put that scale in another context, the comparative size of a nanometer to a meter is the same as that of a marble to the size of the earth.

A colloid mill is a type of rotor-stator mixer often used in the manufacturing of emulsions and dispersions. It can also be used to reduce the particle size of solids in suspension. Inside the colloid mill, a high-speed rotor pushes the fluid through small holes in a stationary stator, creating extremely high levels of mechanical shear.
