In this work, mesostructured silica nanoparticles (MSN(AP)) with high adsorptivity were prepared by a modification with 3-aminopropyl triethoxysilane (APTES) as a pore expander. 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 A catalyst containing small (ca. 2.5 nm) and crystalline Pt nanoparticles embedded into the walls of a mesostructured silica framework was found to be highly active in alkene hydrosilylation reaching TONs of ca. 105.

Abstract. Large pore mesoporous silica nanoparticles (LP-MSNs) functionalized with poly-l-lysine (PLL) were designed as a new carrier material for gene delivery applications. The synthesized LP-MSNs are 100–200 nm in diameter and are composed of cage-like pores organized in a cubic mesostructure. 2015-01-15 · Mesostructured silica nanoparticles (MSN) represent a potential support, which has a high surface area and contains acidic/basic features , , , .

Here, we developed perfluorocarbon-loaded ultraporous mesostructured silica nanoparticles (PERFUMNs) as 19 F MRI detectable oxygen-sensing probes. Ultraporous mesostructured silica nanoparticles (UMNs) have large internal cavities (average = 1.8 cm 3 g -1 ), facilitating an average 17% loading efficiency of PFCs, meeting the threshold fluorine concentrations needed for imaging studies. 2.5.2.2 Mesostructured Silica Nanoparticles (MSN) 35 2.5.3 Generation of Defect Structure by Alkaline Treatment 35 2.5.4 Modification with Other Semiconductors 37 2.6 Techniques of Catalyst Characterization 39 2.6.1 Determination of Structural Properties 39 Ordered mesoporous materials are unique materials that are defined by an ordered and repetitive mesostructure of pores and disordered arrangement at the In this article, we describe a novel concept for PAH removal from aqueous solutions using cyclodextrin-functionalized mesostructured silica nanoparticles ( 23 Mei 2017 Poly-L-lysine Functionalized Large Pore Cubic Mesostructured Silica Nanoparticles as Biocompatible Carriers for Gene Delivery.

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. 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. Biocompatible mesoporous silica nanoparticles (MSNs) has been being extensively explored for intracellular drug delivery for reversing the MDR of cancer cells, such as intranuclear drug delivery,,,, P-gp siRNA transfection,, and Bcl-2-targeted siRNA delivery. 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.

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.
