3. colloids
   Two-phase systems in which one is uniformly dispersed in another as particles small enough so they cannot be filtered or will not settle out. The dispersing or continuous phase or medium envelops the particles of the discontinuous phase. All three states of matter can form colloids among each other. ... (12 Dec 1998) ...

4. colloids
   colloids Very small, finely divided solids (particles that do not dissolve) that remain dispersed in a liquid for a long time due to their small size (usually less than 1 mm) and electrical charge. These particles have negligible settling velocity because their small mass have a low gravitational force compared to surface frictional forces.

5. Colloids
   In chemistry, colloids are particles which are intermediate in size between crystalloids that form true solutions and suspensions that eventually settle.
