    We investigated the capability of fine dust particles (FDPs) to be used as stabilizers for preparing emulsions. With the aid of cationic surfactants, it was found that the FDPs formed oil in water emulsions that were extremely stable for a long time period. The stabilization mechanism was quantitatively analyzed via zeta-potential measurements of surface modified FDPs and interface adsorption experiments of FDP-coated microbeads by using optical laser tweezers.
