In the field of modern materials science, Pickering emulsion has become a research hotspot because of its unique stability and controllability.

Pickering emulsion is an emulsion system consisting of solid particle stabilizers dispersed in the oil-water phase, where solid particles or nanoparticles located at the liquid interface are used as stabilizers rather than surfactants, thereby increasing the life of the droplets. In addition, it is more stable and less toxic than emulsions stabilized by surfactants, and is therefore favored in applications in different fields such as drug delivery (as a carrier, improving drug stability and bioavailability), antimicrobial activity, protein recognition, catalysis, photocatalysis, and water purification. In addition, the morphology of nanoparticles has a great influence on the stability and potential utilization of Pickering emulsions.
