Patent ID: 11389785

Abstract:
It is provided a method for obtaining mesoporous silica particles with surface functionalisation comprising the steps of a) providing solutions of at least three precursors; wherein the pH of the mixture is adjusted to a range between 2 and 8 in a buffered system; b) Mixing the precursor solutions thereby allowing a reaction to take place at a temperature between 20 and 60° C., whereby surface functionalized mesoporous silica particles as solid reaction product are formed; c) Separating the surface functionalized mesoporous silica particles from the reaction mixture by centrifugation or filtration; d) Removing any pore structure directing agent present in the pores of the formed surface functionalized mesoporous silica particles by ultrasonication; e) followed by separation by centrifugation or filtration, washing and drying of the surface functionalized mesoporous silica particles.
