colloid

 [kol´oid]
1. gluelike.
2. the translucent, yellowish, gelatinous substance resulting from colloid degeneration.
3. a chemical system composed of a continuous medium (the continuous phase) throughout which are distributed small particles, 1 to 1000 nm in size (the disperse phase), which do not settle out under the influence of gravity. Colloidal particles are not capable of passing through a semipermeable membrane, as in dialysis. Solutes that can pass through a semipermeable membrane are sometimes called crystalloids. adj., adj colloid´al.
dispersion colloid colloid (def. 3), particularly an unstable colloid system.
emulsion colloid lyophilic colloid
rarely, emulsion.
lyophilic colloid a stable colloid system in which the disperse phase is relatively liquid, usually comprising highly complex organic substances, such as glue or starch, which readily absorb solvent, swell, and distribute uniformly through the continuous phase.
lyophobic colloid an unstable colloid system in which the disperse phase particles tend to repel liquids, are easily precipitated, and cannot be redispersed with additional solvent.
stannous sulfur colloid a sulfur colloid containing stannous ions; complexed with technetium 99m it is used as a diagnostic aid (bone, liver, and spleen imaging).
suspension colloid lyophobic colloid.

sus·pen·soid

(sŭs-pen'soyd),
A colloidal solution in which the dispersed particles are solid and lyophobic or hydrophobic and are therefore sharply demarcated from the fluid in which they are suspended.
[suspension + G. eidos, resemblance]

sus·pen·soid

(sŭs-pen'soyd)
A colloidal solution in which the dispersed particles are solid and lyophobe or hydrophobe, and are therefore sharply demarcated from the fluid in which they are suspended.
