Colloid is a term that has come to encompass solid particles suspended in a liquid (a colloidal dispersion), microscopic droplets in a liquid (an emulsion), or either solid or liquid phases suspended in a gas (an aerosol).
Describe the composition and properties of colloidal dispersions. List and explain several technological applications of colloids. As a child, you may have made suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water, known as tempera paint.
We investigate the structure and dynamics of biphasic colloidal mixtures composed of coexisting attractive and repulsive microspheres by confocal microscopy.
11 Σεπ 2022 · A colloid can be classified as a sol, a dispersion of solid particles in a liquid or solid; a gel, a semisolid sol in which all of the liquid phase has been absorbed by the solid particles; an aerosol, a dispersion of solid or liquid particles in a gas; or an emulsion, a dispersion of one liquid phase in another.

Examples. Continuous phase is often water. Wide range of sizes: bovine serum albumin: 3 nm. cells: tens of microns. Classify colloids as hydrophobic (e.g., carbon black) or hydrophilic (e.g., red blood cell). Stability of colloid: essential part of its function. whether or not it will coagulate.
30 Ιαν 2023 · A colloid is one of the three primary types of mixtures, with the other two being a solution and suspension. A colloid is a mixture that has particles ranging between 1 and 1000 nanometers in diameter, yet are still able to remain evenly distributed throughout the solution.
