  "term": "Protected lyophobic colloid",
  "field": "Chemistry",
  "definition": "A lyophobic colloid that has been stabilized against coagulation by the adsorption of a protective layer of a lyophilic substance. This adsorbed layer creates a steric or electrostatic barrier, preventing the colloidal particles from aggregating. Gelatin or gum arabic are common protective agents for gold sols.",
