“…into micrometer sized porous materials. [6][7][8] After distributing and binding to the huge surface of micrometric porous materials, the agglomeration of drug nanoparticles is forbidden because they are limited in the internal or external surfaces of the porous materials. The drugs will thus have nanometric size and large surface area after composition with porous particles.…”

Mesoporous silica SBA-15 (SC) and template occluded SBA-15 (SP) were used to increase the bioavailability of silybin, an extremely poorly water soluble drug. Silybin was introduced into SC and SP by assembling or self-assembling methods. The results of X-ray powder diffraction, differential scanning calorimetry (DSC) and N2 adsorption-desorption experiment indicated that amorphous silybin was successfully introduced into the mesopores in both SC and SP samples. The transmission electron micrograph (TEM) images revealed that the structure of the mesoporous materials was not destroyed after the drug loading. Results of dissolution rate tests and animal experiments showed that both SC and SP can significantly improve the bioavailability of silybin, SP was thus preferred because the template needs not to be removed by calcination or extraction.

Mesoporous silica with worm-like pore channels was synthesized using mixed P123 (polyethyleneoxide-polypropylene oxide-polyethylene oxide triblock copolymer EO 20 PO 70 EO 20 ) and ionic cosurfactant {CTAB, SDS or N-myristoyl-D-alanine (C 14 -D-A)} as a structure-directing agent, and the pore-expanding effect of different amount of PEG-400 on the worm-like pore channels was studied. The synthesized products were characterized using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and nitrogen sorption analysis. Moreover, the worm-like pore-expanded mesoporous silica was extracted with solvent, and the obtained quaternary ammonium functionalized mesoporous silica with different pore size was applied to immobilize laccase respectively. The stability of immobilized laccase, the optimum pH value acquired and reusability for the degradation of 2,4-DCP were also studied. Through comparative studies, it is found that, matching of sizes between the enzyme molecule and the pore diameter of the mesoporous silica, is essential for specific activity of immobilized laccase and degradation efficiency of 2,4-DCP by immobilized laccase.
