Among the mesoporous silica micellar templated structures (MTSs), MSU‐X silica, obtained through an N 0 I 0 assembly between non‐ionic polyethyleneoxide‐based surfactants (N 0 ) and silica neutral inorganic precursors (I 0 ), exhibits a regular ordered structure with a 3D wormhole porous framework and an easily controlled pore size. These materials have been tested for applications requiring both a narrow mesopore size distribution and isotropic properties. A specific double‐step synthesis that we developed recently for MSU‐X materials has allowed us to prepare mesoporous silica particles with the required shape, size, and properties. Both the particles’ synthesis and comparative HPLC separation tests with a commercial ungrafted silica HPLC powder of identical shape and size are reported.
