ABSTRACT:
The present invention provides for evaporation induced self-assembly (EISA) within microdroplets produced by a vibrating orifice aerosol generator (VOAG) for the production of monodisperse mesoporous silica particles. The process of the present invention exploits the concentration of evaporating droplets to induce the organization of various amphiphilic molecules, effectively partitioning a silica precursor to the hydrophilic regions of the structure. Promotion of silica condensation, followed by removal of the surfactant, provides ordered spherical mesoporous particles.
