1. colloidnoun

   A stable system of two phases, one of which is dispersed in the other in the form of very small droplets or particles.

2. colloidnoun

   An intimate mixture of two substances one of which, called the dispersed phase (or colloid), is uniformly distributed in a finely divided state throughout the second substance, called the dispersion medium (or dispersing medium). The dispersion medium may be a gas, a liquid, or a solid, and the dispersed phase may also be any of these, with the exception that one does not speak of a colloidal system of one gas in another. A system of liquid or solid particles colloidally dispersed in a gas is called an aerosol. A system of solid substances or water-insoluble liquids colloidally dispersed in liquid water is called a hydrosol.

3. colloidnoun

   A particle less than 1 micron in diameter, following the Wentworth scale

4. colloidadjective

   Glue-like.

5. Etymology: From ‘glue’ + -oid.

1. Colloid

   A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance. Some definitions specify that the particles must be dispersed in a liquid, while others extend the definition to include substances like aerosols and gels. The term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word suspension is distinguished from colloids by larger particle size). A colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension). The dispersed phase particles have a diameter of approximately 1 nanometre to 1 micrometre.Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid. Other colloids may be opaque or have a slight color. Colloidal suspensions are the subject of interface and colloid science. This field of study was introduced in 1845 by Italian chemist Francesco Selmi and further investigated since 1861 by Scottish scientist Thomas Graham.

1. colloid

   A colloid is a type of mixture wherein small particles of one substance are dispersed uniformly within another substance. These particles are larger than molecules but smaller than what can be seen with the naked eye, thus the mixture appears to be homogeneous, even though it's not on the molecular level. Examples include milk, fog, and gelatin.

1. Colloidadjective

   resembling glue or jelly; characterized by a jellylike appearance; gelatinous; as, colloid tumors

2. Colloidnoun

   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

3. Colloidnoun

   a gelatinous substance found in colloid degeneration and colloid cancer

4. Etymology: [Gr. ko`lla glue + -oid. Cf. Collodion.]

1. Colloid

   A colloid is a substance microscopically dispersed throughout another substance. The dispersed-phase particles have a diameter of between approximately 1 and 1000 nanometers. Such particles are normally invisible in an optical microscope, though their presence can be confirmed with the use of an ultramicroscope or an electron microscope. Homogeneous mixtures with a dispersed phase in this size range may be called colloidal aerosols, colloidal emulsions, colloidal foams, colloidal dispersions, or hydrosols. The dispersed-phase particles or droplets are affected largely by the surface chemistry present in the colloid. Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid. Other colloids may be opaque or have a slight color. Colloidal solutions are the subject of interface and colloid science. This field of study was introduced in 1861 by Scottish scientist Thomas Graham.

1. Colloid

   kol′oid, n. a name given by Graham, in contradistinction to crystalloids, to any soluble substance, which, when exposed to dialysis, does not pass through the porous membrane.—adj. Colloid′al. [Gr. kolla, glue, and eidos, form.]
