Mobile Composite Material (MCM-41) was modified by the addition of various functional groups, which increase the materials’ efficiency for an assortment of applications. Mesoporous materials have demonstrated to be capable of adsorbing and releasing of model drug molecules, rhodamine 6G and ibuprofen. Mesoporous silica materials functionalized with mercaptopropyltrimethoxysilane (MPTS), vinyltrimethoxysilane (VTS), aminopropyltrimethoxysilane (APTS), and N-(2-animoethyl)-3-aminopropyltriethoxysilane (AAPTS) were used to test the adsorption and release of rhodamine 6G (R6G) and ibuprofen. The vinyl and mercaptopropyl groups adsorbed and released more rhodamine 6G than the primary and secondary amine groups. The adsorption and release of ibuprofen was the opposite of the R6G experiment with the primary and secondary amine groups, which were found to be the only samples to adsorb and therefore release ibuprofen.
