In this paper, we develop a simple and general method for the fabrication of yolk/shell structures through a one-step encapsulation of particles by SiO2 shells in aqueous mixtures of lauryl sulfonate betaine (LSB) and sodium dodecyl benzenesulfonate (SDBS). Various yolk/shell structures with different particle cores, such as SiO2@SiO2, Au@SiO2, and Fe2O3@SiO2, have been successfully prepared.
