Surface Properties of Synthesized Nanoporous Carbon and

The physicochemical properties of catalysts were investigated by several techniques, including N2 physisorption measurements, powder X-ray diffraction, N2 Herein, we took advantage of a BF 4 − anion hydrogen bonding strategy to anchor a chiral cationic rhodium/diamine complex within base‐functionalized mesostructured silica nanoparticles conveniently to construct a bifunctional heterogeneous catalyst. The surface of α-Fe2O3 nanoparticles was successfully coated with mesostructured silica templated by surfactant assemblies using cetyltrimethylammonium ions. By repeating the coating operation, it was possible to control the thickness of the mesostructured silica phase. Abstract: 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 and unfunctionalized silica nanoparticles.

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. 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.

3 The CTAB surfactant was removed by calcination at 550 °C for 5 h. Attachment of the ICPES linker was accomplished by suspending 100 mg of the calcined particles in 10 mL of a 10 mM solution of ICPES in dry PhMe and refluxing for 12 h under N 2 . 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. 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.

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. 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.

More importantly, no Pt leaching was detected. This result is remarkable because Pt leaching Pure mesoporous silica nanoparticles were prepared according to published literature procedure. 3 The CTAB surfactant was removed by calcination at 550 °C for 5 h.
