Acoustic cavitation leading to the morphosynthesis of mesoporous silica vesicles

A direct and efficient synthesis route to form vesicles of mesoporous silica by a sonochemical method in a very short preparation time is outlined. This approach does not require any specialized structure-directing reagents other than the normally used cetyltrimethylammonium bromide (CTAB) as the surfactant similar to the original work to prepare mesoporous silicates.
