What's the difference between colloid and particle?

Colloid


Definition:

  • (a.) Resembling glue or jelly; characterized by a jellylike appearance; gelatinous; as, colloid tumors.
  • (n.) A substance (as albumin, gum, gelatin, etc.) which is of a gelatinous rather than a crystalline nature, and which diffuses itself through animal membranes or vegetable parchment more slowly than crystalloids do; -- opposed to crystalloid.
  • (n.) A gelatinous substance found in colloid degeneration and colloid cancer.

Particle


Definition:

  • (n.) A minute part or portion of matter; a morsel; a little bit; an atom; a jot; as, a particle of sand, of wood, of dust.
