Abstract

The mesoporous silica vesicles and spheres with high surface area, large pore size and pore volume have been conveniently synthesized by using cationic-anionic binary surfactant system as template. The size of the mesoporous silica vesicles and sphere is uniform and ranged from 50-200 nm. In addition, these mesoporous silica nanoparticles possess the autofluoresce. The morphology and mesostructure are dependent on the pH value of the reaction solution.
