Designing the surfactant appropriately can result in the mesoporous silica having an interior surface that is uniquely modified. In the example shown in Fig. 4.21, a surfactant with an aUcoxysilane head is covalently connected to the inner surface of a mesporous sihca through a sol-gel reaction. Selective removal of the alkyl tail by acid hydrolysis leaves open pores densely populated with functional groups. Since the surfactant bites the sihca wall and removes its tail, this method is called lizard templating .
