Context #1 | Adjective

scientific term

Colloidal refers to a substance consisting of microscopically dispersed insoluble particles within a liquid or gas. These colloidal particles are often so small that they can remain suspended and do not settle out easily. This property is crucial in various applications like medicine, chemistry, and material science.

Synonyms

dispersed, emulsified, suspended

Examples of usage

  • Colloidal silver is often marketed as a natural antibiotic.
  • In a colloidal solution, particles do not settle down.
  • Colloidal gold can be used in medical treatments.

Etymology

The term colloidal is derived from the word 'colloid', which has its origins in the Greek word 'kolla', meaning 'glue'. The term was first introduced in the late 19th century to describe a mixture where microscopic particles are evenly dispersed in a medium, creating a stable dispersion. The chemistry of colloids became a prominent field of study as scientists began to understand the unique properties and behaviors of these mixtures. Colloidal systems are significant in various scientific applications, including understanding biologically relevant phenomena, formulating paints, plastics, and pharmaceuticals, and in the field of food technology. Colloidal chemistry is an essential branch of physical chemistry that explores the properties and interactions of these tiny particles.
