The present chapter describes the synthesis, characterizations, and application of MCM-48 functionalized by an inorganic moiety, as a carrier. MCM-48 functionalized by 12-tungstophophoric acid (TPA) (TPA-MCM-48) and L-arginine was loaded into pure as well as functionalized MCM-48. Both the materials were characterized by various physicochemical techniques and evaluated for in vitro release of L-arginine at body temperature under different conditions. A study on release kinetics was carried out using first-order release kinetic model, while the mechanism were by Higuchi model. Further, to see the influence of TPA on release rate, release profile obtained from pure and functionalized MCM-48 was compared.
