Palladium (Pd) nanoparticles were deposited on the surface of halloysite nanotubes (HNTs) modified with γ-aminopropyltriethoxysilane (APTES) to produce Pd/NH2-HNTs nanocomposites. The results indicated that Pd nanoparticles were densely immobilized onto NH2-HNTs with an average diameter of ~ 3 nm. The Pd distribution on the surface of silanized HNTs showed much more uniform, and the Pd nanopart...

We developed a potential immunostimulatory double-stranded DNA (dsDNA) delivery system by the binding of dsDNA to amino-modified mesoporous silica nanoparticles (MSNs) to form MSN-NH2/dsDNA complexes. Serum stability, in vitro cytotoxicity, cell uptake, and type I interferon-α (IFN-α) induction of MSN-NH2/dsDNA complexes were evaluated. The results showed that MSN-NH2 nanoparticles had no cytot...

Palladium nanoparticles have been immobilized into an amino-functionalized metal-organic framework (MOF), MIL-101Cr-NH2, to form Pd@MIL-101Cr-NH2. Four materials with different loadings of palladium have been prepared (denoted as 4-, 8-, 12-, and 16 wt%Pd@MIL-101Cr-NH2). The effects of catalyst loading and the size and distribution of the Pd nanoparticles on the catalytic performance have been ...

In this article, we describe the application of surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) with the use of amine functionalized graphene-coated cobalt nanoparticles (CoC–NH2 nanoparticles) to analyse aromatic hydrophobic compounds that are known environmental contaminants, including polycyclic aromatic hydrocarbons (PAHs) and pentachlorophenol (PCP). Our results d...

In this study, we proposed to modify mesoporous silica nanoparticles (MSNs) with 3-aminopropyltriethoxysilane (NH2-TES), aminoethylaminopropyltriethoxysilane (2NH2-TES) and 3-[2-(2-aminoethylamino)ethylamino] propyl-trimethoxysilane (3NH2-TES) for binding of cytosine-phosphate-guanosine oligodexynucleotides (CpG ODN), and investigated the effect of different amino groups of MSNs on the CpG ODN ...

In the present study, the permeabilities of CO2 and CH4 in terms of ideal and actual CO2/CH4 selectivity were investigated through the synthesized membranes of poly (ether-block-amide) (Pebax 1657) accompanied with poly (ethylene glycol) (PEG 400) and NH2-MIL125 nanoparticles. NH2-MIL125 nanofillers were added to the blend of PEG...

This work reports the solvothermal synthesis of a titanium-based metal organic framework (NH2-MIL-125(Ti)) and further deposition palladium, platinum silver nanoparticles on its framework, with aim to obtain visible light-driven photocatalysts. The structure NH2-MIL-125 was not affected by incorporation nanoparticles, while textural properties changed depending used. All M/NH2-MIL-125 (M = Pd, ...

Fe3O4 nanoparticles were synthesized and functionalized with (3-aminopropyl) trimethoxysilane (APTMS) chitosan, forming Fe3O4-NH2 Fe3O4-NH2-chitosan nanoparticles. The by a co-precipitation method functionalization was performed in further stages. characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), zeta potential, transmission electron microscopy (TEM). result...

A novel amino-functionalized silica-coated nanoscale zerovalent iron (NZVI@SiO2-NH2) was successfully synthesized by using one-step liquid-phase method with the surface functionalization of nanoscale zerovalent iron (NZVI) to enhance degradation of chlorinated organic contaminants from anaerobic microbial system. NZVI@SiO2-NH2 nanoparticles were synthesized under optimal conditions with the uni...
