In a new double-step synthesis of MSU-X type silicas, which was reported previously, a first step allows the preparation of a colorless stable and homogeneous aqueous solution where both nonionic surfactants and silica oligomers are mixed. Dynamic light scattering (DLS), small angle X-ray scattering (SAXS) and Si NMR analyzes revealed that this first step allows the assembly of surfactants and silica oligomers in specific micellar hybrid objects that are described.
