Synthesis and characterization of mesoporous Fe/SiO2 for magnetic drug targeting

Optimization of tetracycline hydrochloride adsorption on amino modified SBA-15 using response surface methodology

“…Higuchi model due to chemical and physical entrapment of the drug [59][60][61][62][63]. Thus, the drug release from mesoporous materials is diffusion control similar to other drug delivery systems such as biopolymers or hydrogels [2].…”

Sorption of Pb(II) and Cu(II) onto multi-amine grafted mesoporous silica embedded with nano-magnetite: Effects of steric factors

“…Impregnation of MNPs into the pore channels of ordered mesoporous silica can introduce a large amount of MNPs in a highly dispersed state, leading to an increase of their separation [20]. Nevertheless, the impregnated MNPs could be attributed to a decrease in surface area and pore volume resulting from blockage and distortion of pore channels [21]. In this study, therefore, we synthesized mesoporous silica loaded with nanoscale magnetite (Fe 3 O 4 ) (hereafter, denoted as MSU-F-S/Fe 3 O 4 ) for the purpose of magnetic separation.…”

Facile synthesis of ordered magnetic mesoporous γ-Fe2O3/SiO2 nanocomposites with diverse mesostructures

“…In catalysis, these nanocomposites provide not only large surface areas for high loading of catalysts but also the ability to be easily separated from reaction mixture by means of the application of an external magnetic field. In the biomedical field, they offer high loading of drug/bioactive agents as well as the ability to selectively target the desired organs or tissues inside the body [19,20]. These nanocomposites, which combined the advantages of OMS and Mag-NCs, open new opportunities to generate multifunctional platforms possibly applied in complicated situation, e.g., site-selective and controlled drug release [11,12,21,22].…”
