 (dī-ăl′ĭ-sĭs)
n. pl. di·al·y·ses (-sēz′)
1. The separation of smaller molecules from larger molecules or of dissolved substances from colloidal particles in a solution by selective diffusion through a semipermeable membrane.
2. Medicine Any of several techniques, especially hemodialysis and peritoneal dialysis, in which filtration through a semipermeable membrane is used to remove metabolic wastes and excess fluid from the blood of people with kidney failure.

[Greek dialusis, separating, dissolution, from dialūein, to break up, dissolve : dia-, apart; see dia- + lūein, to loosen; see leu- in Indo-European roots.]
