Colloidal particle is a small amount of matter having size typical for colloids and with a clear phase boundary (phase colloids). A group of such particles (aggregate, agglomerate) or being a macromolecule (e.g. solution of polymer molecules is a molecular colloid) or a molecular aggregate (e.g. micelle).
A colloidal sized particle is defined in diameter from 1-1000 nanometers. Soluble particles smaller than this will form a solution as opposed to a colloid.
Famous quotes containing the word particle:
“Love is life. All, everything that I understand, I understand only because I love. Everything is, everything exists, only because I love. Everything is united by it alone. Love is God, and to die means that I, a particle of love, shall return to the general and eternal source.”
—Leo Tolstoy (1828–1910)
