Tuning and controlling the shape of mesoporous silica particles with CTAB/sodium deoxycholate catanionic mixtures
Controlling the shape and size of mesoporous silica particles (MSPs) requires a deep understanding of the different parameters that play a major role during the synthesis of the materials. One of the key factors that can determine the morphology and porosity of the systems is the surfactant, used as a templating agent. We have very recently proven that binary mixtures of hexadecyltrimethylammonium bromide (CTAB) and bile salts are templating systems effective in controlling the morphology of MSPs in a facile and non-costly way.
