Mesoporous silica nanoparticles (MSN) was synthesized and modified with 3-aminopropyltriethoxysilane (APTES) using co-condensation (MSNco) and post-grafting (MSNpost) methods. X-ray diffraction (XRD) and transmission electron microscopy (TEM) data confirmed the formation of ordered mesostructured silica nanoparticles. The performance of MSNs was then tested on an ibuprofen immobilization and release. The results revealed that unmodified MSN demonstrated the best immobilization rate and capacity of ibuprofen (98%), MSNpost exhibited higher ibuprofen adsorption (78%) as compared to MSNco (71%), suggesting the modification method is not the dominant factor for the adsorption studied. In fact, according to the FT-IR results, the silanol groups density was found to be the contributing factor that affected the adsorption. The in vitro drug release was also investigated with simulated biological fluids. In 20 h, MSN co showed the fastest release of ibuprofen (100%), followed by MSN (50%) and MSNpost (38%). Both pore size and amine groups influenced the rate of the release process. From the results, MSN and MSNpost is suggested to have suitable features for slow drug release which provides constant release over a defined period to avoid repeated administration. While MSNco could be best employed as a fast release system that provides initial burst of drug release to achieve rapid and maximum relief. © 2013 Elsevier Inc.
