The film "The Colloidal State" explores the concept of colloids, which are materials in a dispersion where small particles of one substance are distributed throughout another. It distinguishes ...

Colloidal suspensions—homogeneous suspensions of undissolved particles in a liquid, which are widespread in nature—tend to separate out over time if colloids strongly attract with each other. A major ...

Colloidal suspensions undergo Brownian diffusion that arrests at high density, remobilizing under flow. Slowly sheared non-Brownian particles (dry or in suspension) likewise show chaotic trajectories, ...

Occasionally referred to as ‘colloidal gold,’ gold colloid is a suspension comprising sub-micron gold nanoparticles suspended in a solvent - most commonly water. Gold nanoparticles' distinct ...
