Core/shell silica-based in-situ microencapsulation: A self-templating method

Core/shell SiO2 and (RSiO1.5)(1-x)-(SiO2)(x) (R = alkyl) microcapsules were synthesized via a single-step O/W emulsion system using a self-templating method; the facile synthetic process provides an in-situ encapsulation route for a wide range of lipophilic functional compounds.
