Herein, through immobilization, the location of two catalytic species is controlled: Faujasite silica is another form of crystalline silica. It is obtained by dealumination of a low-sodium, ultra-stable Y zeolite with a combined acid and thermal treatment. The resulting product contains over 99% silica, and has high crystallinity and surface area (over 800 m2/g). Faujasite-silica has very high thermal and acid stability. 1999-03-01 2010-08-17 2000-01-21 A versatile synthetic protocol is reported that allows high concentrations of functionally active membrane proteins to be incorporated in mesostructured silica materials.

The ability to deliberately place molecules possessing desired activities in specific spatially separated regions of the nanostructure is an important feature of these Mesoporous silica nanoparticles (MSNs) have garnered a great deal of attention as potential carriers for therapeutic payloads. Here, we report a pH-responsive drug-carrier based on chondroitin sulfate functionalized mesostructured silica nanoparticles (NMChS-MSNs) ie, the amidation between NMChS macromer and amino group functionalized MSNs. Mesostructured silica nanotubes with tube diameter less than 100 nm are still desired because the fascinating properties of one-dimensional nanostructure were generally induced by nanosize-effect , , , , .
