Monodisperse nanoparticles and colloids provide this potential. Counterions are the mobile ions in ion exchange polymers and colloids. Radionuclides and heavy metals easily sorb onto colloids suspended in water. Common hydrophilic molecules include colloids, cotton, and cellulose (which cotton consists of). Emulsions are part of a more general class of two-phase systems of matter called colloids. Globular proteins are somewhat water-soluble (forming colloids in water), unlike the fibrous or membrane proteins. He called the diffusible solutes crystalloids and those that would not pass the membrane colloids. For initial fluid replacement colloids or albumin is preferred in people with cirrhosis. Debye length is an important parameter in plasma physics, electrolytes, and colloids (DLVO theory). The compound forms colloids when dissolved in water. This is done by spraying colloids on average containing only one particle per droplet. It is the surface chemistry of mineral and organic colloids that determines soil's chemical properties. It also has countless applications in technology of colloids, e.g., flotation of minerals. Depletion forces are used extensively as a method of destabilizing colloids. The additive that prevents the colloids from forming flocs is called a deflocculant.
