The detection of extracellular vesicles, or exosomes are important mediators in intercellular communication and often play a role cancer progression. CD63 is key exosomal protein due to its distinctive cellular functions association with many cancers. This describes label-free electrochemiluminescence (ECL) nanoimmunosensor for the over mesoporous carbon screen-printed electrode (MC-SPE) modifi...

An ultrasensitive and selective electrochemical immunosensor was developed for the detection of hepatitis C virus (HCV) core antigen. The immunosensor consists of graphitized mesoporous carbon-methylene blue (GMCs-MB) nanocomposite as an electrode modified material and a horseradish peroxidase-DNA-coated carboxyl multi-wall carbon nanotubes (CMWNTs) as a secondary antibody layer. After modifica...

in this study, removal of acid blue 62 from aqueous solution by mesoporous silicate mcm-41 modified by aminopropyltriethoxysilane (aptes) composite was studied. properties of synthesized composite were analyzed and confirmed by sem, edx and ftir. results show that langmuir adsorption isotherm has the best compatibility with the results of experiments. kinetic analysis using pseudo-first-order m...

agal2o3 nanocomposite were synthesized by solution combustion technique using ammonium carbonate as a new fuel under simultaneous combustion of alumina and silver particles condition. samples prepared with different amount of silver, were characterized by xrd, bet, sem and optical absorption measurements. xrd analysis was used to determine the change in phase and size of the synthesized nanopar...

Inorganic–organic hybrid structures have become innovative alternatives for next-generation dye-sensitized solar cells, because they combine the advantages of both systems. Here, we introduce a layered sandwich-type architecture, the core of which comprises a bicontinuous three-dimensional nanocomposite of mesoporous (mp)-TiO2, with CH3NH3PbI3 perovskite as light harvester, as well as a polymer...

Abstract Nanocomposite of magnetic Fe 3 O 4 nanoparticles and polypyrrole was prepared under sonication by a new chemical polymerization method during which acted both as pyrrole oxidant component in the composite material. Synthesis this nanocomposite carried out aqueous solution acidified to pH 2, prerequisite for formation these types material facilitate oxidation nanoparticles. In way, two ...

Changes in the inherent solid phase and aqueous interfacial properties of magnetite nanoparticles in a Massart type magnetic fluid were investigated. Magnetite nanoparticles were synthesized, purified, dialyzed against 0.001 mol dm–3 HCl and then stored at 4 °C for 6 years. The solid phase transformation of magnetite to maghemite and formation of akageneite shell on the magnetic core, as well a...

Hierarchical organization of gold nanorods was previously obtained on a substrate, allowing precise control over the morphology of the assemblies and macroscale spatial arrangement. Herein, a thorough description of these gold nanorod assemblies and their orientation within supercrystals is presented together with a sol-gel technique to protect the supercrystals with mesoporous silica films. Th...

Mesoporous and conventional Fe-containing ZSM-5 catalysts (0.5–8 wt% Fe) were prepared using a simple impregnation method and tested in NO selective catalytic reduction (SCR) with NH3. It was found that mesoporous Fe-ZSM-5 catalysts exhibit higher SCR activities than comparable conventional catalysts. Furthermore, conventional Fe-ZSM-5 catalysts have maximum activity at ~ 2.5 wt% Fe while for t...

To avoid the side effects caused by nonspecific targeting, premature release, weak selectivity, and poor therapeutic efficacy of current nanoparticle-based systems used for drug delivery, we fabricated natural material-decorated nanoparticles as a multifunctional, membrane-controlled targeted drug delivery system. The nanocomposite material coated with a membrane was biocompatible and integrate...
