Formation of Yolk/SiO(2) shell structures using surfactant mixtures as template.
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 SiO(2) shells in aqueous mixtures of lauryl sulfonate betaine (LSB) and sodium dodecyl benzenesulfonate (SDBS). Various yolk/shell structures with different particle cores, such as SiO(2)@SiO(2), Au@SiO(2), and Fe(2)O(3)@SiO(2), have been successfully prepared.
