Evaporation‐driven surface templating by means of a vibrating orifice aerosol generator (VOAG), a device that produces microdroplets, has been used for the synthesis of non‐hollow monodisperse mesoporous silica particles (see Figure for a TEM image). Particle and pore size as well as mesoscopic order are controllable by varying the experimental conditions, precursor chemistry, and VOAG parameters.
