Abstract Mesoporous silica nanoparticles (MSNs) is an attractive candidate as a drug delivery carrier due to their large surface area, high pore volume and t intrinsic biocompatibility. Here, MSNs were synthesized by the hydrolysis and condensation of tetraethyl orthosilicate (TEOS) with cetyltrimethylammonium bromide (CTAB) acting as structural directing agent. A large mesopore with diameter of 3.8 to 5.5 nm of MCM-41style can be obtained via the addition of 1,3,5-trimethylbenzene. Metoprolol tartrate as a selective beta 1 receptor blocker was embedded on MSNs by the incipient wetness impregnation. The delivery profiles were collected in vitro in SBF at pH 7.4. A close correlation can be observed between the drug release kinetic and the mesopore size and specific surface area of MSNs.
