 Pickering emulsions, a type of emulsion stabilized by solid particles at the oil-water interface, have been discovered and studied extensively for their stability against coalescence in useful properties. They can be applied in various fields such as biomedicine, food, fine chemical synthesis, cosmetics, etc., by tuning the types and properties of solid emulsifiers.
