Organic modified mesoporous MCM-41 through solvothermal process as drug delivery system

Abstract MCM-41 materials modified by organic aminopropyl groups have been successfully prepared through solvothermal process and have been used as drug-controlled delivery system of aspirin. The results show that the releasing properties of this delivery system are affected by the amount of aminopropyl groups on the pore wall and the ordered structure of mesoporous materials. These materials were characterized by XRD, TG, FT-IR, TEM, UV and N 2 adsorption.
