2-Chlorobenzoylthiourea-modified MCM-41 for Drug Delivery

Mesoporous 2-Chlorobenzoylthiourea-modified MCM-41 was prepared and loaded with ibuprofen in a supercritical carbon dioxide (sC-CO2) environment. 2-chloro-benzoythiourea modified MCM-41 was prepared and also characterized via XRD, FT-IR, SEM and BET techniques. The (100) and (110) reflections observed at low angle XRD show the mesoporous SiO2 structure. The paticule size of non-uniform spheres were observed at a range of 250-305 nm. BET surface areas were calculated as 1506 m2 / g for MCM-41 and 306 m2/g 2-chloro-benzoythiourea modified MCM-4, respectively. The absorption and releasing studies of ibuprofen were caried out in simulated body fluid. The result revealed that high adsorption capacity for drug with 2-chloro-benzoythiourea modified MCM-41 and slower drug release rate was achieved.
