Solid materials can be dispersed in the colloidal suspension if their sizes are very small, in the order of ten nanometers.

|
Surfactants are dispersion agents for objects in liquid that work by adhering to objects and creating a new repulsion between them, raising the energy required for objects to aggregate, and stabilizing the colloid.

|
Nanometer materials can be synthesized in solution, starting with their atomic ion forms, by controlled oxidation and reduction reactions.

Physics: Magnetic materials are sources of magnetic fields and are subject to forces arising from the magnetic fields of other sources
|

|
|
Physics: Magnetic fields contain energy and act as vector force fields
