“Contains only pure water and pure gold nanometer sized particles.” “Smallest gold nanoparticles whose diameter typically measure 3.2 nm” “Colloidal gold is nanoparticles of pure gold suspended in pure water. The gold nanoparticles in Mesogold are a few nanometers in diameter (a nanometer is a billionth of meter). These particles are so small they can only be seen by the most powerful electron microscopes available today. An atom of gold is about 0.288 nanometers in diameter, so the gold nanoparticles in Mesogold are only about eleven times the diameter of a single gold atom.”
