Coelho JV(1), Guedes MS, Barrera D, Sapag K, Pereira MC, de Oliveira LC. Author information: (1)Departamento de Química, ICEx, Universidade Federal de Minas Gerais, 31270-901 Belo Horizonte, Minas Gerais, Brazil. Mesoporous silica nanoparticles are promising materials for drug delivery and other biomedical applications because they are nontoxic and can be taken up by living cells. Through appropriate design and synthesis, multifunctional mesoporous silica nanoparticles for sophisticated bio‐applications are created. Silica, mesostructured (MCM-41) is a part of low-density organized mesoporous silicate system which has a 2D hexagonal phase, prepared in the presence of quaternary ammonium halide surfactant. It has ordered and large pores with diameter in the range 1.5-10 nm and specific surface area of 1500 m 2 /g.

The performance of the MSN(AP) was tested by the adsorption of MB in a batch system under varying pH (2-11), adsorbent dosage (0.1-0.5 g L(-1)), and initial MB concentration (5-60 mg L(-1)). 2017-07-01 · Core-shell hierarchical mesostructured silica nanoparticles for gene and chemodrug co-delivery in sequence: We have successfully developed a “chemical homology” strategy for the fabrication of core-shell hierarchical mesostructured MSNs (H-MSNs) with different-sized mesopores and composition-varied frameworks separately in the core and shell. 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. 2014-04-05 · Nickel promoted mesostructured silica nanoparticles (Ni/MSN) were highly active for CO 2 methanation due to the presence of intra and interparticle pores which led to increase the number of oxygen vacancy in the catalyst. While, Ni has a role in the dissociation the molecular hydrogen to form atomic hydrogen.

In this study, colloidal 30 nm HSNs were prepared by adding organically bridged alkoxysilane to an aqueous dispersion of mesostructured silica-surfactant composite nanoparticles, and the temporal changes of the morphology and chemical state of the nanoparticles were monitored to elucidate the formation mechanism.

RESULTS AND DISCUSSION Synthesis of Large Pore Mesoporous Silica Nanoparticles (LP-MSNs). Abstract This study reports an efficient method for the preparation of well-dispersed ruthenium nanoparticles of controlled size loaded into micelle-templated silica (MTS). This method is based on an organometallic approach consisting in mild decomposition of Ru(COD)(COT) (COD = η 4 -cycloocta-1,5-diene; COT = η 6 -cycloocta-1,3,5-triene) embedded inside mesostructured porous silica.
