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

The electric field generated in the sedimentation or centrifugation of charged colloidal particles could be exploited to determine the charge and the mass of macromolecules in a single experiment. In ...

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 ...
