Syntheses and Characterization of Bulky Mesoporous Silica MCM-41 by Hydrothermal Hot-Pressing Method
This research provided a novel enzyme-responsive antimicrobial carrier aiming at overcoming the volatile loss of active antibacterial components, by employing mesoporous silica nanoparticles (MCM-41) as matrix encapsulation and Zein molecular gate. Since could be consumed bacteria, Zein-functionalized MCM-41 acted an gate improved controlled-release capacity. The results showed that amount caps...
The goal of the present study was to compare the drug release properties and stability of the nanoporous silica with different pore architectures as a matrix for improved delivery of poorly soluble drugs. For this purpose, three dimensional ordered macroporous (3DOM) silica with 3D continuous and interconnected macropores of different sizes (200 nm and 500 nm) and classic mesoporous silica (ie,...
Large-pore three-dimensional (3D) mesoporous silicas are among the most interesting mesoporous materials discovered in recent years, and they have attracted much attention for potential applications requiring easily accessible, uniform, large pores. Examples of these are SBA-15 (p6mm) and SBA16 (Im3̄m), which have cylindricaland cage-type structures, respectively. It has been reported that hexag...
