Cephalosporin release from functionalized MCM-41 supports interpreted by various models

Loading and release of 5-fluorouracil from HY zeolites with varying SiO2/Al2O3 ratios

“…The amount of the drug released from HY-5 is almost negligible ($5%) over the period of 300 min. Release profiles for drug molecules adsorbed in porous media can be analyzed using empirical [38] or mechanistic models [39][40][41][42]. In this work, the release profiles were fitted to the first order kinetic model for drug release from a porous matrix [38,43].…”

Catalytic behavior of surfactant-containing-MCM-41 mesoporous materials for cycloaddition of 4-nitrophenyl azide

“…The lack of hydrothermal stability of the mesoporous materials has been overcome by the incorporation of heteroatoms such as Al, Ga, Ti, Fe, V, W and Cr [4][5][6][7]. These properties allow these mesoporous materials to be used in a wide range of applications such as catalysis [4][5][6][7], adsorption [8,10], extraction [11], energy [12], drug delivery systems [13], and for their luminescent character [14].…”

Double barrier as an effective method for slower delivery rate of ibuprofen

“…Drug delivery rate could be controlled by different factors, including organic modification of the mesoporous material surface. The materials could be functionalized with various silylating agents like aminosilanes (Munoz et al, 2003;Zhu et al, 2005;Song et al, 2005), vinylsilane (Maria et al, 2012) or alkoxysilanes (Doadrio et al, 2006).…”
