Abstract
A method for self-assembling a mesoporous silica nanoparticle. The method comprises the step of condensing a silica precursor, a surfactant and a condensation agent in a solvent. Then, the addition of an organotriethoxysilane is performed. Finally, there is the step of removing the surfactant. The method is remarkable in that the portion of the organotriethoxysilane to the silica precursor is comprised between 5% and 15%. Additionally, a self-assembled mesoporous silica nanoparticle comprising at least one silica precursor and an organotriethoxysilane.
